Seemingly blissful summer evenings happen. Sitting outside, without a care. No mosquito spray, citronella candles, long sleeves or pants — big oops! So what do you do the next day (or even day after) when the welt(s) from the unintended mosquito fest seem out of control?
Family nurse practitioner Allison Folger, CNP, says mosquito bites are simply a nuisance for many but explains they can get infected if you don’t leave them be.
“Scratching the bite to the point of bleeding can open the door for a bacterial skin infection to develop,” Folger explains. “This commonly occurs in children whose nails are understandably dirty from playing outside, though it also happens in adults. ”
The infection’s not the mosquito’s fault!
The infection, called cellulitis, is from bacteria that enters the punctured skin from your hands. Warning signs include:
- Swelling of the lymph nodes.
- A wide-spreading redness around the mosquito bite.
- Red streaking that extends beyond the initial bite.
- Pus or drainage.
- Area feels warm to the touch.
- Fever (above 100 F).
“If you or a child has these signs of infection, it is important to see your doctor,” Folger says. One easy way to tell if the bite is spreading? Take a pen and draw an outline around the mosquito bite. That’s a fool-proof, objective way to keep an eye on it.
If your doctor confirms it’s cellulitis, you’ll need a round of antibiotics to kill the bacteria (typically strep (streptococcus) or staph (staphylococcus).
How to treat it in the meantime?
If you’ve got a mandarin orange-sized welt that you’re worried about, here’s the best way to treat it: Folger recommends cleaning the bite with soap and water, and then applying an over-the-counter hydrocortisone cream. This will help reduce the swelling and itching.
If desired, this can be followed with calamine lotion, which contains a mild topical anesthetic that may ease the discomfort.
“Use ice packs on the area to help bring the inflammation down, and reapply the topical medication every four hours,” she recommends.
Your healthcare provider may also recommend using an oral antihistamine (such as Benadryl®), as they’re more effective at providing relief than topical creams.
Infected or just a itchy aggravation? You’ll probably be fine soon with proper care either way, Folger says. And getting bitten so badly may just remind you to take an ounce of prevention next time.
Insect Allergies | AAFA.org
Many people think of warm weather when they think of insect allergies. Warm weather does signal the arrival of some unwanted visitors like stinging and biting insects. However, you can find two very common “bugs” all year long in homes and buildings. Neither one needs to bite or sting you to cause an allergic reaction, but both trigger allergy and asthma in many people.
What Kinds of Insects Cause Allergic Reactions?
There are many different kinds of insects or “insect-like bugs” that can cause an allergic reaction:
Bees, wasps, hornets, yellow-jackets and fire ants are the most common stinging insects that cause an allergic reaction. When these insects sting you, they inject a toxic substance called venom. Most people stung by these insects recover within hours or days. In others, this venom can trigger a life-threatening allergic reaction.
Mosquitoes, kissing bugs, bedbugs, fleas and certain flies are the most common biting insects known to cause an allergic reaction. Most people bitten by insects suffer pain, redness, itching, stinging and minor swelling in the area around the bite. Rarely, insect bites may trigger a life-threatening allergic reaction.
A bite from a Lone Star tick can cause people to develop an allergy to meat. These ticks carry alpha-gal (a sugar). When a tick bites a person, it transfers alpha-gal into the bloodstream. The person’s immune system then reacts to it. Alpha-gal is also found in mammal meat (beef, lamb, pork). If you have allergy symptoms after eating meat, see an allergist.
Non-stinging and non-biting insects can also cause allergic reactions, particularly cockroaches and insect-like dust mites. These two insects may be the most common cause of year-round allergy and asthma. Unlike a cockroach, a dust mite is too small to see with the naked eye. The cockroach and dust mite’s waste and body cause allergic reactions. They also can trigger asthma symptoms and asthma attacks.
What Are the Signs of an Allergic Reaction to Insects?
Most people stung or bitten by insects suffer pain, redness, itching and minor swelling in the area around the bite or sting. This is a normal reaction. Most people get better within hours or days.
An allergic reaction to insects that don’t sting or bite, like cockroaches or dust mites, is different. You may sneeze, cough, have a runny or stuffy nose, or itchy eyes, nose, mouth or throat. These symptoms can be confused with the common cold, but last for weeks or months at a time. If you have asthma, an allergic reaction could trigger asthma symptoms or an asthma attack.
People can have a serious allergic reaction to stinging or biting insects. A life-threatening allergic reaction (anaphylaxis) produces signs and symptoms that require immediate medical attention. Without immediate treatment, anaphylaxis may cause death. Symptoms usually involve more than one organ system (part of the body), such as the skin or mouth, the lungs, the heart, and the gut. Some symptoms include:
- Skin rashes, itching or hives
- Swelling of the lips, tongue or throat
- Shortness of breath, trouble breathing or wheezing (whistling sound during breathing)
- Dizziness and/or fainting
- Stomach pain, vomiting, bloating or diarrhea
- Feeling like something awful is about to happen
Other serious but non-allergic reactions include:
- A toxic reaction that happens when the body reacts to insect venom like it is a poison. A toxic reaction can cause symptoms similar to those of an allergic reaction. Other symptoms include nausea, fever, fainting, seizures, shock and even death.
- Serum sickness which is an unusual reaction to a foreign substance in the body. It can cause symptoms hours or days after the sting or bite. Symptoms include fever, joint pain, other flu-like symptoms and sometimes hives.

Insect Bite–like Reaction in Patients With Hematologic Malignant Neoplasms | Allergy and Clinical Immunology | JAMA Dermatology
Exaggerated reaction to insect bites, mainly to mosquitoes, is infrequently described in patients with chronic lymphocytic leukemia. Skin lesions usually appear months to years after the diagnosis of leukemia and are unrelated to laboratory findings, disease course, or therapy.
We describe 8 patients with various hematologic disorders (chronic lymphocytic leukemia, acute lymphoblastic leukemia, acute monocytic leukemia, mantle-cell lymphoma, large-cell lymphoma, and myelofibrosis) who developed insect bite–like reaction. Although the clinical picture and the histological characteristics of the lesions were typical for insect bites, none of the patients actually had a history, course, or response to treatment suggestive of arthropod assaults. In 2 patients, the eruption preceded the diagnosis of the malignant neoplasm. The rash persisted for months to years and was resistant to therapies other than systemic corticosteroids. The 3 patients with chronic lymphocytic leukemia seemed to have a worse prognosis than expected for their disease. In 1, the polymerase chain reaction detected leukemic cells in the infiltrate.
Insect bite–like reaction is an infrequent, disturbing, and difficult-to-treat nonspecific phenomenon in patients with hematologic malignant neoplasms. Since it may precede the hematologic disorder, oriented evaluation is warranted. We speculate that immunodeficiency plays a role in its pathogenesis; however, the exact pathogenesis and its prognostic implications await further studies.
SKIN ERUPTIONS are common in patients with hematologic malignant neoplasms. These can be due to either cutaneous involvement by malignant cells (specific lesion) or a nonmetastatic (paraneoplastic or nonspecific) phenomenon.1,2 Among lesions in the latter group, exaggerated reaction to insect bite is infrequently described in patients with chronic lymphocytic leukemia (CLL).3-7 We describe 8 patients with various hematologic diseases in whom insect bite–like reaction occurred and discuss this phenomenon.
From 1995 to 1998, 8 patients who had characteristic itchy papular or vesiculobullous eruption suggestive of insect bites were referred to our dermatologic clinic. In all patients, the diagnosis of the hematologic disease was based on peripheral blood findings (absolute lymphocytosis >5 × 109 lymphocytes/L for patients with CLL) and on either bone marrow or lymph node biopsy results. All patients were followed up for the clinical course of their eruption and their disease.
In total, 13 skin biopsies were performed in all patients. Sections (4 µm thick) from the formalin-fixed paraffin-embedded blocks were stained with hematoxylin-eosin. Sections were also stained with pan B-cell marker (CD20, mouse anti–human monoclonal L26), pan T-cell marker (CD45RO, mouse anti–human monoclonal UCHL1, and CD3, rabbit anti–human polyclonal antibody), and anti–Epstein-Barr viral (EBV) proteins (mouse monoclonal CS1-4) (all obtained from DAKO Ltd, Glostrup, Denmark) using the standard streptavidin-biotin immunoperoxidase technique. In 2 cases, parts of the biopsy specimens were frozen in liquid nitrogen. Direct immunofluorescence with antibodies against IgG, IgM, IgA, C3, and fibrinogen was performed. In all cases of B-cell lymphoma or leukemia, to detect malignant cells in the infiltrate, the polymerase chain reaction performed on the paraffin-embedded sections was used as previously described.8 In brief, DNA was extracted from 5-µm-thick sections of the paraffin-embedded blocks and was amplified using the seminested procedure with primers Fr3A and LJH in the first 30-cycle round and Fr3A and VLJH in the second 20-cycle round. Each reaction contained DNA, 1 µL; the selected primers, 10 pmol; each deoxynucleotide triphosphate, 200 µmol/L; magnesium chloride, 4 or 5 mmol/L; dimethyl sulfoxide, 10% vol/vol; and Taq polymerase and buffer, 0.2 U, supplied by the manufacturer (Bioline, London, England). The first round of the polymerase chain reaction cycle consisted of annealing for 30 seconds at 56°C, extension for 1 minute at 72°C, and denaturation for 30 seconds at 94°C. The annealing temperature in the second round was 60°C. Before each round, the reaction was heated to 94°C for 4 minutes, and after each round, a final extension step of 6 minutes was performed. Polymerase chain reaction–amplified material was electrophoresed in 2% agarose gel in Tris-boric acid EDTA (TBE) buffer, 250 V, for 25 minutes.
Clinical features of the 8 patients are summarized in Table 1. In all patients, the clinical appearance was that of red itchy papules or plaques (Figure 1). In 1 patient (patient 3), edematous, almost bullous, lesions developed (Figure 2). In another patient (patient 6), 1 of the lesions evolved to a persistent ulcer. Lesions were equally distributed on exposed and nonexposed areas, and there was no seasonal variation in their appearance. None of the patients reported or recalled either insect bites or outdoor activities. A single lesion persisted for about a week and then resolved, seldom leaving postinflammatory hyperpigmentation. Recurrent lesions were the rule. The maximal duration of the rash was 5 years (patients 5 and 6). None of the patients had peripheral eosinophilic leukocytosis.
Patient Characteristics and Clinical Data on the Insect Bite–like Reaction*
Red papules, some with excoriations, in a patient with mantle-cell lymphoma after 5 years of the disease and a chemotherapy course.
Edematous eroded plaques in a patient with chronic lymphocytic leukemia.
Only 3 of the 8 patients had CLL. In all of them, the eruption appeared months to years after the diagnosis of leukemia. In 2 patients, 1 with mantle-cell lymphoma (patient 5) and 1 with acute monocytic leukemia (patient 7), the rash preceded the diagnosis of the hematologic disease by 24 and 6 months, respectively. All 3 patients with CLL seemed to have an accelerated course of their disease, more than expected; 1 patient (patient 3) died from transformation to Richter syndrome, and in 2 patients (patients 4 and 6) chemotherapy was initiated due to expansion of the malignant clone, which caused severe pancytopenia. In all patients but 1 (patient 8), no temporal relation was detected between the eruption and therapy for the hematologic disease when this was given. In this patient, the insect bite–like reaction appeared soon after a chemotherapy course (a combination of cyclophosphamide, doxorubicin hydrochloride, vincristine sulfate [Oncovin], and prednisone) had been initiated.
All patients were treated with antiscabies agents because when considering the clinical appearance in some patients, the histological characteristics, and that those patients were either immunosupressed or hospitalized, scabies had to be excluded. Patients were also instructed to avoid outdoor activities and to use repellents and insecticides. All these measures were of no benefit, and the rash persisted. Treatment with topical antipruritic agents, topical corticosteroids, and systemic antihistamines caused no or only temporary relief. Only systemic corticosteroids in a dose equivalent to prednisone, 40 mg/d or more, were effective in suppressing the eruption. However, lesions recurred when corticosteroids were tapered. Improvement was also seen in 1 patient who received combined chemotherapy for his disease, but this is probably due to the fact that corticosteroids were included in the regimen used. In 1 patient (patient 1), the rash disappeared after natural phototherapy at the Dead Sea, and in another 2 patients (patients 5 and 8), 3 months of UV-B phototherapy was either not or only partially beneficial. Low-dose chlorambucil alone was also ineffective in 1 of these patients. Interferon alfa caused only temporary relief in 1 patient (patient 3). In another patient, who was cured from her acute lymphoblastic leukemia (patient 2), the eruption resolved spontaneously.
All biopsy specimens showed a superficial and deep perivascular and interstitial infiltrate composed of small lymphocytes and eosinophils (Figure 3). The density of the infiltrate varied among cases. A biopsy specimen of 1 of the bullous lesions obtained from patient 3 revealed massive subepidermal edema, reminiscent of that seen in Sweet syndrome. Most of the lymphocytes stained with the T-lymphocyte markers. Both T-lymphocyte markers (CD45RO and CD3) stained approximately the same percentage of cells in the infiltrate. In 7 of the 8 patients, T lymphocytes constituted more than 90% of the infiltrate. In 1 patient with CLL (patient 6), B cells exceeded 30% of the infiltrate. Only in this patient, the polymerase chain reaction detected monoclonality, implicating the presence of leukemic cells in the infiltrate. Epstein-Barr viral proteins were not detected in any biopsy specimen. The results of direct immunofluorescence were negative in both cases in which it was tested.
Left, A biopsy specimen shows a superficial, deep, and interstitial perivascular infiltrate involving also the subcutaneous fat (original magnification ×20). Right, The infiltrate is composed of lymphocytes and eosinophils (original magnification ×200).
Patients with CLL may present an exaggerated reaction to insect bites. 3-7 One case is also reported in a patient with lymphocytic lymphoma.9 In all cases but 1,7 skin lesions appeared months to years after the diagnosis of leukemia or lymphoma and were unrelated to laboratory findings, disease course, or therapy given.3-7,9 The term “exaggerated reaction to insect bites” was coined by Weed3 and adopted by others5-7,9 because the lesions either were large or developed bullae.
The diagnosis of insect bites in all reports, including ours, was based on the morphologic and histological characteristics of the lesions. However, from the 31 patients with this phenomenon described in the English-language literature, only 11 recalled arthropod assaults, mainly mosquitoes.3-7,9 Weed3 also found a marked positive cutaneous reaction to mosquito antigen in 5 of his 8 patients. In all patients in the present study, neither the history nor the distribution, course, or efficacy of the preventive measures and treatment supported the assumption of exaggerated reaction to arthropod assault. In 1 patient, it may be related to the chemotherapy, and in another, it may represent leukemia cutis. Therefore, it might be that insect bites are not necessary to initiate the eruption, and terms like “insect bite–like reaction” or “eosinophilic eruption of hematoproliferative disease” should be preferred. Furthermore, the insect bite–like reaction in these patients shares features or may be even identical to the papular rash described in patients with human immunodeficiency virus infection.10,11 Therefore, immunodeficiency combined with various immunologic stimuli (insect bites, drugs, or viral infections) may play a role in the pathogenesis of both eruptions. It is also likely that Wells syndrome, which has been described in patients with malignant hematologic disorders,12 is nothing but a variant of this insect bite–like reaction.13,14
The present series further elucidates aspects of this response. First, the phenomenon occurred not only in patients with CLL but also in patients with other hematoproliferative diseases, thus emphasizing its generality as a “nonspecific” phenomenon in these diseases. Second, the rash may precede the diagnosis of the hematologic disorder, and an oriented evaluation is recommended when lesions persist. Interestingly, most of the hematologic diseases in our patients originated from B cells (3 cases of CLL, mantle-cell and large-cell lymphomas, and acute lymphoblastic leukemia). One may, therefore, speculate that a common mechanism (cytokine imbalance with excess of interleukin 4 and interleukin 5) leads to proliferation of malignant B cells and altered immune response characterized by eosinophilic infiltrate.15 Alternatively, the neoplastic B cells may be responsible for the skin hypersensitivity reaction.
In Japan, hypersensitivity to mosquito bites was associated with natural killer (NK)–cell lymphocytosis.16 Most of these patients developed malignant histiocytosis years later. In 1 report,17 a patient who was hypersensitive to mosquito bites and had EBV infection developed NK-cell lymphoma. Recently, a relation between hypersensitivity to mosquito bites and clonal proliferation of EBV DNA–positive NK cells was found. 18 The researchers suggest that this may be responsible for the hypersensitivity and for a leukemic transformation. Marker CD45RO stains T lymphocytes and NK cells. Marker CD3 stains only T lymphocytes. Since we did not find a notable difference between these stains in the biopsy specimens from patients with an insect bite–like reaction, only a small percentage of NK cells was present. Therefore, it may be inferred that NK cells did not play a major role in the development of this reaction. Our findings also do not support a role for EBV in the evolution of the insect bite–like reaction. Although these observations may reflect the different epidemiological characteristics of EBV infection between East Asia and western countries, the 2 hypersensitivity reactions may be totally different phenomena, for which the molecular mechanism requires further investigation.
Our cases further support the evidence that this rash is unrelated to bullous pemphigoid.4,7 However, since there are reports of bullous pemphigoid associated with malignant neoplasms,19,20 it is mandatory to perform direct immunofluorescence whenever pemphigoid is clinically suspected as histological features alone are not sufficient to rule out pemphigoid.
Specific lesions as traditionally defined, ie, leukemia cutis or lymphomatous infiltration of the skin, can be ruled out based on the immunophenotype and the molecular biology assays. In 1 patient with CLL who developed a persistent ulcer, the infiltrate contained malignant B cells; thus, it may actually represent leukemia cutis. However, this can merely be a reflection of the distribution of neoplastic cells in the blood and their capability to respond to immunologic stimuli.21
In all the published cases of insect bite–like reaction,3,5-7,9 the eruption was unrelated to laboratory findings, disease course, or therapy given. This is also the trend in the present series. However, the observation on the 3 patients with CLL who showed progression of their disease in a relatively short period merits special attention. Fatal complications also developed in 3 of the 8 patients with CLL described by Davis et al. 7 Larger series are required to establish whether this reaction has prognostic implications for patients with CLL, especially in light of the recent observation that prognosis is not affected by specific skin infiltrates in patients with CLL.22
The insect bite–like reaction in these patients seems to pose a therapeutic challenge. Davis et al7 reported variable improvement in some of their patients who underwent chemotherapy for the CLL. Oral glucocorticoids and intravenous immunoglobulin seemed to work better, while antibiotics were not helpful at all. None of the patients in the present series responded sufficiently to most measures (topical treatment with antipruritics and corticosteroids, systemic antihistamine therapy, UV-B phototherapy, isolated chemotherapy, and interferon therapy). Only prednisone, 40 mg/d or more, was effective in suppressing the rash. The observation of 1 patient who responded to Dead Sea phototherapy may implicate that psoralen–UV-A may be beneficial. Disappearance of the eruption in the patient who was cured from her leukemia further stresses the interrelation between the 2 situations.
In summary, insect bite–like reaction should be included in the various nonspecific rashes accompanying hematoproliferative disorders. Clinicians should be aware of the fact that this phenomenon may precede the diagnosis of the hematologic disorder; thus, an oriented investigation is recommended. Beside corticosteroids, therapy for this disturbing eruption awaits further studies; its pathogenesis requires further study as well.

Why do mosquito bites itch?
Every summer it’s the same story. It doesn’t matter if you are sitting on a terrace, playing volleyball, taking a walk, or trying to sleep. Without noticing even the slightest touch on your arms or legs, the infamous red rashes appear. Then is when the worst moment arrives: you begin to itch like crazy and you can’t stop doing it because if you do, the itchiness only gets worse.

Human blood, its favorite
For all mosquito species, only the females bite humans. They don’t do it for self-defense like bees. It’s also not their only source of food since both males and females drink nectar from flowers. What the females need are the proteins found in animal blood in order to develop eggs, and humans, being animals, also count among their prey.
When a female lands on your skin it looks for a capillary under the skin using its palps, sensory appendages on the front of the head. Once on top of the capillary, it uses a trumpet-shaped organ called the proboscis, an appendage which is more or less equivalent to a mouth. The proboscis is made up a number of different organs, and inside it are the stilettos. These are used to pierce the skin until the blood vessel is found. Once found, the mosquito begins to drink blood using a different part of the proboscis only used to suck blood, the labrum.
While the mosquito sucks blood, it simultaneously injects its saliva into the area using a different tube, the hypopharynx. The saliva contains anti-coagulant proteins, allowing a continuous flow of blood and stopping the closing of the pierced area. This way, the mosquitos can drink blood quickly without us noticing.

An allergic reaction
Our immune system detects the mosquito saliva proteins as antigens, foreign substances, and interprets them as an attack. As a response, some of the blood cells produce antibodies in the area around the bite. These antibodies stimulate the mast cells, a cell type of the immune system. When activated, the mast cells produce histamines: these substances activate the inflammatory response in order to protect the individual.
When the histamines arrive to the affected area they widen the blood vessels in order to move better. As a result, the skin becomes inflamed and creates a rash or swelling around the bite. By affecting our sensory nerve endings, this irritation causes the itching sensation.
Itching only makes it worse
This is when we get to work, itching non-stop. But what we don’t know is that itching only makes the situation worse because we are stimulating the mast cells. This causes them to release even more histamines, and as a result the itchiness only increases, a viscous cycle which can only be stopped if we are able to resist the urge to itch. With so much itching it is quite easy to scrape away the skin, often leading to a small dermatological infection because under our fingernails there is a considerable amount of bacteria.
If we are able to resist long enough, the inflammation will reduce thanks to the natural response of our bodies. However, in the worst cases an even greater allergic reaction may occur, requiring antihistamines and cortisone to stop it. The greatest ally for soothing the itchiness is ice because cold works as an anesthesia on nerve endings and makes it so we don’t notice the itchiness as much. Use ice cubes out of the freezer wrapped in a cloth, or store a soothing or moisturizing cream in the freezer: this will offer the double effect of the cold as well as its other intended effects.
When to call a doctor
Bug bites: They itch, they’re an eyesore, and always have you asking, “Does this look normal?”
The first step is to figure out what bit you. If it was a flying or buzzing insect, it was likely a mosquito or fly. If the sting was sudden and painful, that’s a bee or a wasp. Did you find a tick attached to your skin? How about physically see a spider bite you? Perhaps it’s even a rash or wound that occurred for no apparent reason.
Here are the most common biting bugs and what to watch for. As always, if you are having trouble breathing after a bug bite, call 911 or go to the emergency room.
North American mosquitoes are generally harmless, but can sometimes carry diseases, including West Nile virus. In tropical climates (Africa, Central and South America), mosquitoes can carry malaria, Zika virus, yellow fever, and other nasty diseases.
When to call a doctor
Call a doctor if you experience the following symptoms, which could be signs of a mosquito-borne illness:
- Body aches
- Skin rash
- Swollen lymph nodes
Treating mosquito bites
Scratching mosquito bites might seem like a solution for your itch, but it’s actually the opposite — and might create an open wound, which could lead to infection. Topical hydrocortisone (OTC) cream or a prescription steroid cream along with an antihistamine can help with the itching.
Bees and Wasps
When bees and wasps are startled, they may see you as a threat and react with a sting. So, leaving them along is a good place to start.
“What stung me?”
If you’re stung by a bee, it’ll leave behind its stinger, which should be visible. On the other hand, wasps (which include yellow jackets), usually just leave you with sudden pain and a small, red bump.
What to watch for
Some allergic reactions to stings can be severe, so if you experience shortness of breath, or any of the following symptoms, call 911 immediately.
- Difficulty breathing
- Swelling of the face or throat
- Prior history of sever reaction to stings
Treating bee and wasp stings
Apply ice or a cool compress to the sting. Take an antihistamine (like Benadryl). If you have been prescribed an EpiPen injector due to previous severe reactions, use it! Milder reactions do not usually require a trip to the ER, but you should still call a doctor to discuss your symptoms and next steps. Multiple stings (any more than five) require immediate medical attention.
“Spider bites” are relatively rare events. They can appear much larger and itch much more than mosquito bites.
When to call a doctor
Spider bites can result in itching and red bumps, a lot like a mosquito bite. The only dangerous North American spiders are the Black Widow and Brown Recluse. These bites can cause painful and obvious signs:
- Severe and local pain
- Ulcers or puss
- Necrotic wound
Call a First Stop Health doctor right away if you suspect a Black Widow bite or show any of the symptoms above.
Ticks are common in forested or grassy areas and can latch on quickly to bare skin. Ticks can carry a variety of illnesses, the most common of which is Lyme disease. Lyme disease is a bacterial illness spread through the bite of an infected black-legged tick, also known as a deer tick.
How to prevent tick bites
To reduce your risk of Lyme disease and other tick-borne illnesses:
- Stay out of tick-prone (brushy or wooded) areas
- Have your yard professionally sprayed annually (if you live in an endemic zone)
- Wear long sleeves and long pants outdoors
- Spray your shoes, pants, and socks with permethrin (not while you are wearing them) and let them dry before wearing
- Spray your skin with 20% DEET (not for small children)
- Search your skin for ticks after being outside
- Use tweezers to carefully remove ticks (without squeezing) if found on your skin. Save the tick (in a sealed plastic bag or jar) for identification and possible testing.
Tick bites start as a small, red flat rash. Unlike a mosquito bite, they do not itch.
When to call a doctor
Talk to a First Stop Health doctor if you develop:
- An expanding red rash that may have a “bull’s eye” center, like the logo for Target
- Extreme fatigue
Lyme disease can cause severe and long-lasting symptoms if treatment is delayed. If caught early, however, it can be treated. Other tick-borne illnesses, including Babesiosis, Powassan fever, and Rocky Mountain spotted fever, can be serious as well. A First Stop Health doctor visit can diagnose and begin treatment of tick-borne diseases.
Fleas, Bed Bugs, and Chiggers
Any of these bites will feel itchy, but are usually harmless. These insects don’t normally carry diseases (rarely, fleas can carry plague, mainly in the desert southwest and great plains), but scratching can cause infection. If you exhibit puss, swelling, or signs of local infection, call a First Stop Health doctor.
Bed bugs are a common nuisance and can be identified by the reddish-brown stains they leave on mattresses and bed sheets. Adult bed bugs are about the size and color of an apple seed. Their bites are small, red and itchy, and often appear in a line. They are typically first noticed upon waking up in the morning. Bed bugs can easily spread by latching onto clothing and traveling to other homes, office lounges, or shared school cubbies. If you suspect bed bugs, research the rash and their removal here.
When to call a doctor
The good news is that bed bugs don’t carry disease. In rare cases, they may cause an allergic reaction. Call a doctor if you experience:
- Enlarged bite marks
- Painful swelling
Talk to a Doctor 24/7

Identify the itch – rash, bug bite, or something else | News, Sports, Jobs
If you enjoy spending time outdoors during the warmer months, it’s inevitable that you will run into pesky plants or annoying insects, especially in Pennsylvania. To avoid succumbing to these seasonal woes, it is important to know what condition you are dealing with, how to avoid these pests, and ways to treat your unpleasant reaction to a rash or bug bite.
Poisonous Plants and Identifying Rashes
The most common poisonous plants that you are likely to encounter are poison ivy, poison sumac, and poison oak. They contain the same oil-like chemical that causes itching and the blistering of skin.
Everyone’s sensitivity to this chemical, urushiol, varies. You may have been exposed several times before and never developed a rash. In other cases, it only takes one exposure for your body to become familiar to the oil and cause red and bumpy patches that develop wherever the plant has touched your skin.
Even though you may be sensitive to urushiol, you may have declining intensity of the side effects that it causes over time. For example, if symptoms of poison ivy, oak, or sumac show at a young age, they might not show as often or as intense in the later years of life.
It is also important to note that the rash caused by these plants is not contagious from person to person. However, the urushiol itself can be transferred from the plant to clothes or objects. The chemical doesn’t necessarily need to be on a plant to cause the rash.
Treating Plant Rashes
Follow these tips to treat various plant rashes:
–To help get rid of the infecting oil-like chemical, wash the affected area with warm, soapy water.
–Make sure to immediately wash the clothing that was worn when you were in contact with the poisonous plant. Also wash any object that might have also touched the plant.
–To avoid infection, do not scratch or pick at blisters.
–Itching can be relieved with topical lotions or creams like calamine or hydrocortisone, applying cold compresses, taking short lukewarm baths, and even taking antihistamine pills.
Identifying Bug Bites and Stings
Bugs can also be the culprit of causing itchiness and unusual marks on your skin this summer. In Pennsylvania, it is common to be bitten by mosquitoes, spiders, ticks, or flies or stung by bees or wasps. Each kind of bite or sting has unique identifiers. It is important to know what they look like so that you can remedy them the most effective way.
–Mosquito – Raised, round surface. May feel dense and can become easy irritated.
–Spiders – Two fang marks, plus a red wound and a bump where the bite occurred. Other spider bites may begin as a red spot with redness and swelling. With time, this area lightens and becomes an irritated blister, bullseye pattern. This blister may become crusty and have the black and blue coloring of a bruise.
–Ticks – Small rash (size of a quarter), bullseye pattern. May have a black dot in the center.
–Flies – Swollen, painful, red, itchy welt/bump.
–Stings – White spot surrounded by red welt, immediate pain.
Treating Bug Bites and Stings
The plant or insect that gives you a reaction determines the kind of treatment you should apply. Some basic first-aid tips can be used as soon as you notice a bite or sting:
–Cleanse the area to prevent dirt from infecting the bite and to wash away any remaining venom.
–Elevate the area if possible and use an ice pack to reduce swelling and pain.
–Use antihistamine medications or make a baking-soda paste with water to reduce pain and itching.
When to Seek Medical Care
Whether it’s a bug or plant that has caused you harm, you should know when you need to seek medical care.
The first thing to look out for is anaphylactic reactions. These reactions mean that you are allergic to the bite and you should seek immediate medical care. Anaphylaxis is serious and can be deadly.
Seek immediate care if you experience:
–Chest tightening/Shortness of breath
–Swelling in other areas of the body, not just the site of the bite
–Nausea, diarrhea, or stomach cramping
–Hives or rash
For rashes caused by plants, seek care if your rash shows no signs of improvement after a week of infection, you have a fever, pus, or tenderness on the rash, or if itching gets worse.

Insect Bite – an overview
Protection from insect bites includes several measures, such as avoiding infested areas, wearing protective clothing, and controlling insect populations, when possible. However, the most effective avoidance measure in most situations is the application of insect repellent to the skin. Several types of repellents are commercially available, and include both synthetic chemicals and plant-derived essential oils.
DEET (N,N-diethyl-3-methylbenzamide, formerly N,N-diethyl-m-toluamide) has traditionally been the most effective and most widely used repellent. 116 DEET is a broad-spectrum insect repellent that is effective against mosquitoes, biting flies, chiggers, fleas, and ticks.117 Higher concentrations of DEET result in longer-lasting protection, although these effects seem to plateau at concentrations >50%. In the USA, DEET is available in variable concentrations in multiple vehicles, including solutions, lotions, creams, gels, pump sprays, sticks, roll-ons, wristbands, and impregnated towelettes.93,116 The mechanism of action of DEET is to provide a vapor barrier which deters the biting insect from coming into contact with human skin.118 Firm guidelines or recommendations for choosing an appropriate DEET concentration are not available. However, it is generally accepted that products with 10–35% DEET will provide adequate protection in most circumstances.93 Some general recommendations for the use of DEET-containing products are listed in Table 18.5.
The use of DEET in young children has been a source of some concern, given rare reports of potential neurologic toxicity. Small amounts of DEET may be absorbed through the skin, yet seems to be completely eliminated (along with its metabolites) within 4 h of application in adults.119 Although the pharmacokinetics are not as well understood in children, reports of neurologic toxicity are rare and, in fact, in one study of data collected by the American Association of Poison Control Centers, infants and children had lower rates of severe adverse events than did adults.120 Many of the reports of DEET-related toxicity involved long-term, heavy, frequent, or whole-body application of DEET, and in some, the product was orally ingested.117,121 The Environmental Protection Agency, in 1998, completed a re-registration eligibility decision for DEET, and in this process included a review of acute, subacute, and chronic toxicity data. The agency concluded that normal use of insect repellents containing DEET poses no significant risks to children or adults, that product labeling would be modified to include recommendations for safe use, and that child safety claims on labels were prohibited, given the lack of appropriate scientific data to support such claims. 117,121,122 Human health risk assessments were conducted for DEET and picaradin (see below), and found no significant toxicological risks from typical use of these repellents.123 The American Academy of Pediatrics, in the Red Book discussion of mosquito bite prevention, recommends repellents with DEET concentrations not exceeding 30%, and following such practical application guidelines as those outlined in Table 18.5.124
DEET-containing insect repellents should be carefully applied as they may damage plastics, rayon, leather, spandex, and other synthetic fabrics. They are not damaging, however, to cotton or wool. In addition, it should be remembered that DEET-containing products are flammable. Combination products containing DEET and sunscreen are not recommended, given the potentially decreased effectiveness of the sunscreen, and the different recommended application frequencies of these two products. Questions about the safety of DEET can be addressed by the EPA-sponsored National Pesticide Telecommunications Network at: www. ace.orst.edu/info/nptn.
Picaridin is a newer insect repellent that is effective against mosquitoes, biting flies and ticks. It is usually used in a concentration of up to 20%. Picaridin is reportedly of similar efficacy to DEET, is odorless, and will not damage plastics or fabrics.118 Prior to its launch in the USA, picaridin was used fairly extensively in Europe and Australia. No serious adverse events have been reported to date. Another synthetic insect repellent available in the USA and Europe is IR3535, which fared poorly in an ‘arm-in-cage’ study when compared to DEET.117
Plant-derived repellents may have repellent activity, but none compare to the effectiveness and duration of action of DEET.93 These products usually contain essential oils from any of several plants, including citronella, cedar, eucalyptus, lemongrass, and soybean. Citronella is the active ingredient in most ‘natural’ repellents marketed in the USA. It has a lemony scent, and is available in an oil and in candles. However, in areas with epidemics of mosquito-borne diseases (such as West Nile virus) or in high-risk settings, these products should not be relied upon as the sole protection from bites. When compared to DEET, a blend of the top three performing essential oils was found to offer some protection against various species of mosquitoes, but significantly less so than the chemical repellent.125
Other approaches to mosquito repellency include ingested garlic or vitamin B1 and treated wristbands, each of which has less consistently demonstrated effectiveness. Permethrin, marketed in a 0.5% concentration (Permanone, Duranon, Cutter Outdoorsmen Gear Guard, Sawyer Clothing Tick Repellent, 3M Clothing and Gear) as a tick repellent, is also available and is sprayed on tents, clothing, and sleeping bags. This product is also effective against mosquitoes, flies, and chiggers, and works as a contact insecticide, resulting in central nervous system toxicity to the insect.
90,000 Algae, mite or cold water? Bathers bathing in Turgoyak are covered with a rash
South Urals residents complained of a strange skin reaction after swimming in Lake Turgoyak.
Residents publish photographs showing that the skin is covered with multiple rashes that resemble hives or insect bites. Also, tourists say that after the lake, some of the whites of the eyes turn red and other symptoms of malaise appear. One of the versions – a duck mite, told “Chelyabinsk Echo” Ekaterina, who bathed in Turgoyak in the period from 25 to 27 June.
“And from our company there are two symptoms. Children have nothing, and adults have a rash, ulcerative spots, itchy, similar to multiple mosquito bites. As we were explained, this is a duck mite. This is the first group of symptoms. The second group is reddening of the whites of the eyes. Some kind of allergic reaction. The third group is temperature. We talked with the locals, they say that there are such exacerbations of the duck tick. He gives such an allergic reaction – itching, everything itches. Someone’s eyes hurt on the second day.The doctor confirmed the infection yesterday, and I was prescribed antihistamines and an antibiotic in my eyes. Two or three years ago there was the same outbreak, ”the girl explained.
Another resident of the region, Yulia, who also recently bathed in Turgoyak, reported that the rash and itching are a reaction to algae.
“It’s just a rash, like a burn of the skin from algae, they bloom. This is not the first year I have been going to Turgoyak, and this happens every year at different times. Usually later. It’s just that this year is a very hot summer, and due to this, burns appeared on the skin.On Monday and Tuesday I was there. The first time I bathed, immediately a burning sensation appeared. I realized that it would be the same as in the previous year. Only this year it has poured out quite a lot, usually a little. I immediately drank an antihistamine. First, there is a burning sensation, then small dots, then they become large, like a mosquito has bitten, ”said Yulia.
Deputy Minister of Ecology of the Chelyabinsk Region Vitaly Bezrukov does not see anything unusual in such a reaction of bathers to the water of Turgoyak.
“This is a banal allergic reaction. The water is absolutely clean in all respects. This is an allergic reaction that occurs in people to conifer pollen or algae. We have been observing this situation for several years. I myself swam in Turgoyak, I had no allergies, ”the official said.
Sergey Zakharov, Honorary Chairman of the Chelyabinsk Regional Branch of the Russian Geographical Society, believes that a rash is generally a skin reaction to cold water.Although he did not rule out duck tick bites.
“The water at Turgoyak is very clean. This is most likely a local reaction to cold water. Because it is cold relative to other lakes. It doesn’t have to be some kind of pollution. There are no many ducks opposite Turgoyak. If this is a duck mite, and they have reliably identified it, then it is. On the surface of the water a week ago, we did not observe any algal blooms or tree pollen. The water is clean, the transparency is more than 10 meters. No changes in water color were observed. These are very clean waters. Like itchy skin, maybe. Maybe a local reaction to the cold. Everyone’s health is different, and it happens that lichen rosacea appears after hypothermia in some people, ”the scientist explained.
At the end of May 2021, the Ministry of Ecology of the region announced that the water in Lake Turgoyak became cleaner. This was shown by the results of physical and chemical analysis. At the end of 2019, the water in Turgoyak belonged to the 3rd quality class “moderately polluted”.In 2020, it is already characterized by class 2 as “clean water”, the ministry said.

mosquito control methods, indoor mosquito control methods
The annoying buzzing at night, biting hands and feet after outdoor recreation are the two main reasons for the general dislike of mosquitoes. These petty bloodsuckers are capable of depriving sleep and tranquility of anyone, even a person who is strong in spirit and body.
Why are they biting us?
There are about 3600 species of blood-sucking mosquitoes (Culicidae).They inhabit all continents except Antarctica. Mosquitoes feed on nectar and plant juices. Blood is drunk only by females after mating – it contains the necessary proteins and energy for growing eggs. After drinking, they wait several days until the blood is digested and until the eggs are ripe. One clutch contains from 30 to 150 eggs (rarely – up to 280), and the female can lay them up to 1 time in 2-3 days. Development from an egg to an adult mosquito takes an average of two weeks.
How do mosquitoes choose their prey?
To search for prey, females have chemical and heat sensors that register the release of sweat and carbon dioxide.Figuratively speaking, for them the whole world looks like flows of CO2, and they fly to where there is more of it. Mosquitoes use the carbon dioxide trail to locate the victim several tens of meters away. The more often you breathe, the higher the risk of being bitten, which is why children, pregnant women and people with a large body weight attract mosquito interest. During physical labor or sports, the respiratory rate and the emission of carbon dioxide also increase.
At a distance of about a meter from a potential victim, the mosquito begins to distinguish many parameters: skin temperature, metabolic characteristics and human microflora.They are attracted by the smells of lactic acid, which is contained in sweat, as well as: ammonia, acetone, sulcatone and some carboxylic acids.
Therefore, in order to scare away mosquitoes, you need to try to kill this natural smell. This can be done using chemical or natural remedies.
Mosquito control methods
The most popular modern remedies are repellents.
- Repellents – are used in the form of lotions, creams, ointments, emulsions, aerosols.Depending on the method, they act on the nerve endings of the olfactory organs of insects or when they come into contact with the treated surface.
- Fumigants are smoke-based agents, such as a mosquito coil. The principle of its operation is quite simple: one end of the spiral is set on fire, and it gradually melts. The substances contained in the emitted smoke block the respiratory system of insects and kill them.
- Electrofumigators – special devices powered by the mains.They use either a special plate or a gel that evaporates from heating and releases substances that kill mosquitoes into the air.
- Bracelets for mosquitoes – products that are impregnated with natural essential oils: citronella, mint, lavender and other herbs. Under the influence of heat, their vapors neutralize the smell of carbon dioxide emitted by our body, due to which the mosquito does not feel a person.
Many people are afraid to use such products, due to the widespread belief that they are harmful to health.In addition, there is information about the side effects of some components: people are faced with an allergic reaction to their use. Alternative methods can also be used to stop the smell that attracts mosquitoes. But you need to take into account that they do not give a complete guarantee.
- Essential oils Essential oils can be used to combat natural body odor. Suitable: eucalyptus, cloves, anise, orange, cedar, lavender, tea tree, geranium, mint, thyme.Applications:
- Aroma Lamp: Add 5-7 drops of essential oil, hot water to the bowl and light a candle.
- Scented candles: DIY or take a ready-made candle, add a few drops of essential oil, such as citronella, and light it.
- Cloth with oils: Soak a cloth (towel) with a mixture of water and selected essential oils and place it by the bed before bed. You will sleep well at night.
- Lemon with cloves.
Lemon and cloves are effective mosquito repellents. Insects negatively perceive the aroma of citrus, especially lemon. When combined with cloves, this smell is noticeably increased. In addition, the rich aroma of the spice contributes to disorientation in space and the destruction of the mosquito’s ability to sense human blood.
In order to achieve this effect, take a lemon and cut it in half, and stick 5-8 pieces of dry cloves in two halves.If at home there are only cloves – pour five grams of hot water and let it brew for 15-20 minutes, then apply to your skin with a spray bottle.
Few people know, but insects do not like the pleasant smell of vanilla. How to use the product? Dissolve a teaspoon of vanillin in a glass of water, dampen a cotton swab and wipe the exposed skin. Vanilla water can also be sprayed on clothing or premises.
Basil is suitable for growing at home, as it is unpretentious, grows both in winter and in summer, looks nice and smells good.At the same time, it also repels mosquitoes and flies. It can be grown in pots or containers, both on the windowsill and outdoors. And from its fresh leaves, you can prepare an effective repellent spray: for this they should be soaked in boiling water for several hours, and then mixed with alcohol.
Basil and bird cherry are considered good and readily available mosquito repellents. Finely chop the fresh leaves and flowers of the plants and simply spread them around the room. You can also make a tape to help get rid of annoying insects.To do this, you need paper, on which you need to apply starch or gelatin glue and sprinkle with chopped bird cherry or basil leaves.
Has the same effect as basil. Just place it where insects are suspected – mosquitoes, butterflies, and moths – and forget about their invasion.
Mosquitoes, ants, flies, fleas and mice will forever forget their way home if you spread dried mint on your windowsill. You can also make a repellent spray from it.
Repels mosquitoes due to the presence of citronella in it. It is a natural oil found in ornamental lemongrass that can grow up to 120 cm high and 90 cm wide in one season . The plant grows well in pots or in the ground, in a sunny, well-drained place.
Spruce or pine cones, which need to be thrown into the fire, can save you from annoying insects in nature. A little dried juniper needles will have a similar effect.The smell of cedar oil repels mosquitoes, flies and even cockroaches, which makes it an excellent solution, both outdoors and in the apartment.
Other mosquito repellents
This is the category with the most effective and modern mosquito control products. Its main representatives are technical means that can exterminate insects over fairly large areas. Among which, the following are distinguished:
- Carbon Dioxide Trap is a device that simulates warm-blooded objects (human or animal).Attracted by the heat, the insects fly up close and are caught by the air stream created by a special fan. This stream sucks mosquitoes into a nearby trap. She is a bag from which they cannot get out, and they die.
- Electric trap is a device that looks like a night light. Mosquitoes, attracted by the light in the dark, fall on a metal mesh connected to a voltage source, where they die.
- Ultrasonic Repeller – the device simulates the mosquito squeak that males emit at the moment of danger.Upon hearing this ultrasonic signal, they begin to fly away from its source.
Bitten by a mosquito: what to do?
Why does the bite itch?
Through the proboscis of a mosquito, a special substance saturated with anticoagulants enters the bloodstream, which stops the clotting process in the blood. After, due to the action of histamine, there is swelling, redness and itching. This substance remains in the wound and causes the immune system to produce an allergic reaction.

Earlier, Rospotrebnadzor warned that mosquitoes, which are carriers of West Nile fever, may appear in Russia in the fall. According to the ministry, due to the abundance of rainfall this year, the number of mosquitoes that carry the fever may increase.
“ There were cases of West Nile fever in Russia. The first was in the late 1990s. They were registered in the south of Russia and in neighboring states, in particular, in Kyrgyzstan. The mortality rate is high, about 7%, that is, 7 out of 100 cases can die.In 2010, there was an outbreak in the Volgograd region. There were also outbreaks in the Rostov and Astrakhan regions. The latest data on outbreaks in some regions was in 2013, while the mortality rate has decreased and does not exceed 2%. The likelihood of the emergence of infection exists in the southern regions of Russia “, – said Vikulov.
According to him, it is impossible to distinguish an ordinary mosquito bite from a “feverish” one without a doctor.
“ It is impossible to understand at all, only a specialist can figure it out, an infectious disease doctor, after conducting an examination, can verify the diagnosis ,” the virologist noted.
He also spoke about the symptoms of West Nile Fever and the course of the disease.
“ This disease is dangerous because half of the patients develop meningitis, damage to the central nervous system. Usually a short incubation period, up to 6 days, in rare cases it can be up to four weeks. Characterized by a rapid increase in temperature to 38-40 degrees with “pouring chills”. Before a sharp rise in temperature, there may be increased weakness and fatigue, a decrease or disappearance of appetite, muscle pain, especially in the calf, sweating, headaches.This fever lasts no more than ten days, usually a week. It is accompanied by pain in the eyes, fear of light, “diffuse” muscle pain – in the muscles of the neck, next to the spine. Not always, but there may be joint pain. At the “height of fever” there may be vomiting, drowsiness, in 10% of cases a red rash appears, a decrease in pressure, very rarely pneumonia “, – concluded the interlocutor ” Radio NCH “.
Earlier, Rospotrebnadzor warned that dirofilariasis, Japanese encephalitis, as well as dengue, Chikungunya, yellow, Zika, Rift valleys can be transmitted to humans through a mosquito bite.
To avoid infection, the agency recommends that Russians, when visiting parks and recreation areas on the banks of water bodies, wear light-colored clothing that covers the body. In addition, you must use an insect repellent spray.

In people who do not have sensitive skin, bedbugs do not cause much irritation. They are often confused with the bites of other insects that are not so harmful. Symptoms of the appearance of bloodsuckers are varied. How to determine the presence of new “tenants” read on.
- A large number of numerous bites concentrated in one place or a long line of separate acne.They appear in the morning, as bedbugs eat from 3 am to 8 am.
- Frequency of damage. Bedbug bites on the skin can appear after 2-3 days. Insects are not very voracious. It is enough for them to eat once a week. They do it in an unorganized manner, they eat randomly – today alone, every other day, and so on. They can be found without food for 1 month.
- Odor. Pay attention to the sudden sweetish smell. It somewhat resembles raspberries or almonds.Bedbugs have scent glands. They give off an odor in the event of an imminent danger or when breeding. It should be borne in mind that with a small number of insects, it will be invisible. If you managed to feel it, then it’s time to take serious measures.

- molluscum contagiosum;
- prickly heat;
- scarlet fever;
Bed bug bites. These insects live in furniture, their bites are highlighted by small pimples of bright red color. Red pimples itch quite strongly, but it also depends on the individual’s tolerance of the person. Bedbugs leave behind traces of “paths” and hard seals with a blood center. They bite on the thinnest areas of the skin, namely: arms, legs, neck, less often the back and abdomen. Children are often victims of bedbug attacks due to the presence of the thinnest possible skin of the whole body. To alleviate the condition of the skin, it is recommended to wipe the foci of inflammation with soda solution, ammonia, parsley and potato juice.
Bed bug or Cimex lectularius is a blood-sucking ectoparasite
Flea bites. They pose a danger to children and adults, being a carrier of many diseases (plague, anthrax, encephalitis, and others). A flea attack is not as harmless as a mosquito bite, for example. It differs from the bites of its relatives in that during the puncture of the skin, an acute pain is felt, as if injected with a syringe.The attacks are concentrated on the legs, up to the knees. Pimples on the legs itch a lot and have a pronounced color. Rashes should be treated with tar soap, iodine or brilliant green.

Intolerable itching is present. The rashes are lubricated with antiseptics. They take antipyretics. Antiviral drugs help to avoid complications, but they do not speed up recovery.
Causes of the rash
There are actually more serious reasons why spots appear on the body, like from mosquito bites.They lie both in internal disorders – problems with the liver, circulatory system, autoimmune processes, infectious diseases, and they are formed under the influence of the external environment – overheating in the sun, hypothermia, vibration, etc. Only specialists on the basis of a comprehensive examination, laboratory tests will be able to determine why does the child get acne like mosquito bites.
One of the types of allergies is urticaria, the visible manifestations of which on the skin, like mosquito bites, and itch.Unlike real traces of insects, dense pink-white bumps appear even under clothing, sometimes merging with each other. The outward resemblance to a nettle burn formed the name of the disease.
Search and elimination of an allergen is the basis of therapy. Typical pathogens are plant pollen, medicines, pet hair, individual components of food, environmental factors. The hives rash is often swollen and blistered. Scratching leads to damage to the shell, the formation of a bloody crust.
Dermatologists establish the cause by provocative tests, laboratory tests, give recommendations, prescribe medications to eliminate symptoms. Acute urticaria with the development of Quincke’s edema, loss of consciousness, vomiting requires immediate medical attention.
The disease is expressed by the appearance of a profuse rash all over the body at the same time. There are traces on the skin, like from mosquito bites, but smaller in size, pale pink in color. Concomitant symptoms are manifested in an increase in the occipital lymph nodes, fever, headaches.The rash disappears after 4 days. Young children under 1 year old are recommended to be vaccinated against rubella, since the pathology is characteristic of an early age.
The danger of the disease lies in the growth retardation, mental development of the fetus, if a pregnant woman is affected by rubella. The first rash on the skin is a signal for immediate medical attention.
If there is a slight malaise, fever, then spots on the skin, like mosquito bites – what the doctor can diagnose.The development of chickenpox is manifested in an increase in new spots, swelling of old ones to the state of bubbles with transparent contents. Over time, within 10-15 days, the bubble dries up, and the remaining crust falls off. During the period of vesicle maturation, the child is contagious.
The rash spreads throughout the body, including mucous membranes, hairy integuments. The well-known drugs “Psilobalm”, gel “Fenistil” reduce the painful itching that accompanies the disease.
Vivid symptoms of the disease are manifested in a sharp increase in temperature, problems during swallowing.The tongue at the beginning of the period of the disease is covered with a thick white coating, then becomes red, shiny. The rash, like mosquito bites, but small-point, is more pronounced on the trunk, limbs, thickens in the folds of the skin. After about a week, the skin on the feet and palms begins to peel off. The disease is dangerous with complications in the heart and kidneys. Constant monitoring of blood and urine parameters is required.
The disease develops by analogy with acute respiratory – cough, fever, runny nose, lacrimation.After 3-4 days, a rash similar to mosquito bites spreads across the face, upper chest and itches.

The affected area should be washed and dried naturally. It is necessary to arrange air baths. The use of talcum powder is helpful. Ointments and creams can make the situation worse.
When a person develops acne all over the body, the first thought that appears is the following: an infectious disease or an allergic reaction has developed.In such a situation, you should always consult a dermatologist. Only he will be able to make an accurate diagnosis and prescribe a suitable treatment. First of all, the doctor excludes insect bites or other parasites.
Great importance in complaints should be given not only to the very fact of the presence of a rash, but also to its features. For example, the localization of skin rashes can give the doctor a lot of useful information, especially when it comes to any infectious and inflammatory processes.
It is also necessary to pay attention to the color of the pimple, which can be red, pink, white or even watery.It is very important to determine its shape by its appearance, which ranges from a small papule to a large plaque or nodule.
