What are the key symptoms of scabies bites. How can you differentiate scabies from other skin conditions. What are the most effective treatments for scabies infestations. How long does it take for scabies symptoms to appear after exposure. Can natural remedies help alleviate scabies symptoms.

Understanding Scabies: Causes and Transmission

Scabies is a skin infestation caused by microscopic mites known as Sarcoptes scabiei. These tiny parasites burrow into the upper layer of human skin, where they feed on blood and lay eggs. The infestation leads to intense itching and a characteristic rash.

How does scabies spread. Scabies mites are primarily transmitted through prolonged skin-to-skin contact with an infected person. This often occurs in crowded living conditions or through intimate physical contact. Additionally, the mites can spread through extended contact with contaminated items such as clothing, bedding, or towels used by an infected individual.

• Scabies mites are too small to be seen with the naked eye
• They have a round body and eight legs when viewed under a microscope
• Scabies can affect people of any race or socioeconomic status
• The condition is most common in crowded living environments

Identifying Scabies: Key Symptoms and Signs

Recognizing the symptoms of scabies is crucial for early diagnosis and treatment. The most prominent signs include:

1. Intense itching, especially at night
2. A rash resembling blisters or pimples
3. Gray lines on the skin (burrow tracks)
4. Red, scaly patches

Where does the scabies rash typically appear. While scabies mites can infest any part of the body, they show a preference for certain areas. The most commonly affected regions include:

• Between the fingers and toes
• Around the wrists
• Under the breasts in women
• In the genital area
• On the buttocks
• In skin folds

Differential Diagnosis: Distinguishing Scabies from Other Skin Conditions

Scabies can be mistaken for other skin conditions due to its similar appearance. How can you differentiate scabies from other rashes. Here are some key distinctions:

• Dermatitis: Usually less intense itching, no visible burrow tracks
• Syphilis: Characterized by a single, painless sore in the early stages
• Poison ivy: Typically linear or streaky rash, often with blisters
• Flea bites: Small, red, raised bumps often in clusters or lines

When in doubt, it’s essential to consult a healthcare professional for an accurate diagnosis. They may perform a skin scraping test to confirm the presence of scabies mites or their eggs.

Treatment Options: Medical Interventions for Scabies

Effective treatment of scabies typically involves prescription medications. What are the most common treatments for scabies infestations.

Topical Medications

• Permethrin cream (5%): Applied to the entire body from neck down, left on for 8-14 hours
• Ivermectin lotion (1%): Applied to dry skin and rinsed off after 8-14 hours
• Crotamiton cream or lotion: Applied daily for 5 days
• Sulfur ointment: Applied for 3 nights in a row

Oral Medications

In some cases, especially for severe or widespread infestations, oral medications may be prescribed:

• Ivermectin: A single dose, sometimes repeated after 1-2 weeks

How long does it take for scabies treatment to work. While the medications kill the mites quickly, itching may persist for several weeks. This is due to the body’s ongoing allergic reaction to the dead mites and their waste products. Your doctor may prescribe additional medications to control itching and inflammation during this period.

Natural Remedies: Complementary Approaches to Scabies Relief

While medical treatment is essential for eliminating scabies mites, some natural remedies may help alleviate symptoms and support the healing process. It’s important to note that these should not replace prescribed treatments but can be used as complementary approaches under medical supervision.

Tea Tree Oil

Tea tree oil possesses antifungal and antibacterial properties that may help soothe the skin and reduce itching. How can you use tea tree oil for scabies relief.

• Dilute tea tree oil with a carrier oil before applying to the skin
• Add a few drops to a spray bottle with water to treat bedding and linens

Neem

Derived from the neem tree, this natural remedy has anti-inflammatory and analgesic properties. Neem oil or creams may help reduce pain and inflammation associated with scabies.

Aloe Vera

Known for its soothing properties, aloe vera gel may help alleviate itching and promote skin healing. A small study suggested that aloe vera gel could be as effective as some prescription treatments, though more research is needed to confirm these findings.

Capsaicin (Cayenne Pepper)

While not directly effective against scabies mites, topical application of capsaicin may help reduce pain and itching. Always perform a patch test before using products containing capsaicin, as it can cause skin irritation in some individuals.

Essential Oils

Some essential oils, such as clove oil, have shown potential in killing scabies mites in animal studies. Other oils that may offer relief include lavender, thyme, and nutmeg. However, more research is needed to establish their efficacy in humans.

Can natural remedies cure scabies on their own. While these natural approaches may provide symptomatic relief, they are not proven to eliminate scabies infestations completely. Always consult with a healthcare provider before using any alternative treatments, especially if you are pregnant, breastfeeding, or have underlying health conditions.

The Scabies Life Cycle: Understanding Mite Reproduction

Comprehending the life cycle of scabies mites is crucial for effective treatment and prevention of reinfestation. How long does it take for scabies mites to reproduce.

• Female mites lay eggs under the skin
• Eggs hatch into larvae after about 3-4 days
• Larvae mature into adult mites in approximately 4 days
• Adult mites can then lay the next generation of eggs

This rapid reproductive cycle contributes to the persistent nature of scabies infestations and underscores the importance of thorough treatment.

How long does it take for scabies symptoms to appear after exposure. The incubation period for scabies can be surprisingly long. Symptoms typically develop:

• 4-6 weeks after initial exposure in people who have never had scabies before
• 1-4 days in people who have previously been infested

During this incubation period, infected individuals can unknowingly spread the mites to others, even before they experience symptoms themselves.

Prevention and Control: Minimizing Scabies Transmission

Preventing the spread of scabies is crucial, especially in close-contact environments. What measures can be taken to control scabies transmission.

• Treat all household members and close contacts simultaneously, even if they don’t show symptoms
• Wash all clothing, bedding, and towels used by infected persons in hot water (at least 50°C or 122°F) and dry on high heat
• Items that can’t be washed should be sealed in plastic bags for at least 72 hours
• Vacuum carpets and upholstered furniture thoroughly
• Avoid close skin-to-skin contact with infected individuals until treatment is complete

Are scabies mites able to live on animals or survive away from human hosts. Contrary to some misconceptions:

• Scabies mites do not live on animals – they are specific to humans
• The mites cannot jump or fly
• Scabies mites can only survive for 24-36 hours away from human skin

This information is crucial for focusing prevention efforts on human-to-human transmission and environmental decontamination.

Special Considerations: Scabies in Vulnerable Populations

While scabies can affect anyone, certain groups may be at higher risk or require special attention during treatment. Who is most vulnerable to scabies infestations.

Infants and Young Children

Scabies in infants and young children may present differently:

• The rash may appear on the head, neck, palms, and soles
• Blisters and pustules are more common
• Treatment may need to be applied to the entire body, including the scalp

Elderly Individuals

Older adults, especially those in nursing homes or long-term care facilities, are at increased risk of scabies infestations. They may experience:

• More severe symptoms due to weakened immune systems
• Difficulty in diagnosis due to pre-existing skin conditions
• Increased risk of complications, such as secondary bacterial infections

Immunocompromised Patients

Individuals with weakened immune systems, such as those with HIV/AIDS or undergoing chemotherapy, may develop a severe form of scabies known as crusted or Norwegian scabies. This variant:

• Is characterized by thick, crusted areas of skin
• Can host millions of mites, making it highly contagious
• Requires more aggressive and prolonged treatment

How should treatment approaches be modified for these vulnerable groups. Treatment for these populations often involves:

• Closer monitoring for side effects and complications
• Potential use of oral medications in addition to topical treatments
• Extended treatment durations
• Comprehensive environmental decontamination measures

Healthcare providers must tailor treatment plans to the specific needs and conditions of these vulnerable individuals, ensuring both effectiveness and safety.

Complications and Long-term Effects of Scabies

While scabies is treatable, untreated or severe infestations can lead to complications. What are the potential long-term effects of scabies.

Secondary Bacterial Infections

Intense scratching can break the skin, allowing bacteria to enter and cause infections. Common secondary infections include:

• Impetigo: A highly contagious skin infection
• Cellulitis: A serious infection of the deep layers of skin and underlying tissue
• Folliculitis: Inflammation of hair follicles

Post-scabies Syndrome

Some individuals may experience persistent itching and skin irritation even after successful treatment. This condition, known as post-scabies syndrome, can last for several weeks or months. It is thought to be caused by:

• Ongoing immune response to dead mites and their waste products
• Skin hypersensitivity developed during the infestation

Psychological Impact

The persistent itching, visible rash, and social stigma associated with scabies can have significant psychological effects, including:

• Anxiety and depression
• Sleep disturbances
• Social isolation
• Reduced quality of life

How can these long-term effects be mitigated. Managing the complications of scabies involves:

• Prompt and thorough treatment of the initial infestation
• Careful monitoring for signs of secondary infections
• Use of antihistamines and topical steroids to manage persistent itching
• Psychological support and counseling when needed
• Patient education about the temporary nature of post-treatment symptoms

By addressing both the physical and psychological aspects of scabies infestations, healthcare providers can help patients recover more fully and minimize long-term impacts.

Scabies is caused by the mite known as the Sarcoptes scabiei. These mites are so tiny that they can’t be seen by the human eye. When viewed by a microscope, you’d see they have a round body and eight legs.

You can’t see scabies, so you have to identify them by the rash they cause. Here are a few key indicators:

• The most common symptoms of scabies are a rash and intense itching that gets worse at night.
• The scabies rash looks like blisters or pimples: pink, raised bumps with a clear top filled with fluid. Sometimes they appear in a row.
• Scabies can also cause gray lines on your skin along with red bumps.
• Your skin may have red and scaly patches.
• Scabies mites attack the entire body, but they particularly like the skin around the hands and feet.

Scabies looks similar to rashes caused by:

• dermatitis
• syphilis
• poison ivy
• other parasites, such as fleas

Treatment is usually a topical medication that’s prescribed by a doctor.

To help relieve some of the bothersome symptoms associated with scabies, your doctor may also prescribe additional medications to control itching and swelling.

Itching may continue for weeks, even if the first application of medicine works. Be sure to remain on the lookout for new tracks or bumps. These signs may be indications that a second treatment is necessary.

Anyone exposed to scabies should be treated.

Many natural treatments are available to help relieve the symptoms of scabies, including:

• tea tree oil
• neem
• aloe vera
• cayenne pepper
• clove oil

Tea tree oil

Tea tree oil can heal your skin rash and help stop itching. However, keep in mind that it’s not as effective at fighting scabies eggs deep within your skin.

Add a small amount of tea tree oil to a squirt bottle and spray it on your bed linen and sheets.

Find tea tree oil on Amazon.

Neem

The neem plant eases inflammation and pain. It also has antibacterial properties. Neem is available as an oil and can also be found in soaps and creams online.

Aloe vera

A small study found that aloe vera gel was as good as prescription-strength medication at fighting scabies. If you opt for aloe vera gel, make sure to buy pure aloe vera gel that contains no additives.

Cayenne pepper

There’s little evidence that cayenne pepper can kill scabies mites. But when applied topically, it can reduce pain and itching.

You should always perform the skin patch test before using products made with cayenne pepper or the component capsaicin.

Clove oil and other essential oils

Clove oil is an insecticide and has been shown to kill scabies mites taken from rabbits and pigs.

More research and human studies are needed, but other essential oils may also have the potential to treat scabies. Ones that you can try include lavender, thyme, and nutmeg. Find essential oil kits on Amazon.

People who are pregnant, breastfeeding, or otherwise have health concerns should consult their doctors before trying any of these at-home remedies.

Scabies eggs are laid under the skin and hatch into larvae after about four days. In another four days, the mites are mature and ready to lay the next generation of eggs. This cycle continues until halted by medical treatment.

Scabies can live and breed on your skin for several weeks before your immune system has an allergic reaction and symptoms appear.

Scabies mites don’t live on animals. They crawl and are unable to jump or fly. Scabies mites can’t live away from a human host for more than three days, but they can survive for one to two months with a host.

Bed bugs can’t cause scabies, since scabies is specific to the Sarcoptes scabiei mite. Scabies mites must live in human skin to feed and breed. Bed bugs don’t live in human skin. They feed on blood from humans or animals and are mostly active at night.

In addition, scabies mites are generally smaller than bed bugs. When fully grown, each mite is no bigger than the size of the point of a pin. Bed bugs are reddish-brown, oval-shaped insects with six legs. They can be as large as 1 to 7 millimeters — and so are visible to the human eye.

The mere thought of playing host to a family of scabies mites is unpleasant. It should be noted, however, that scabies mites don’t transmit diseases. That said, extensive scratching could cause secondary infection, such as impetigo.

In rare instances, Norwegian, or crusted, scabies can develop. Usually this more severe version only occurs as a result of a weakened immune system or when a scabies infestation goes untreated for months or years.

what it looks like, symptoms, signs and treatment

Scabies: a definition of the disease

Scabies (or, scientifically, scabies) is a common contagious skin disease.

In the last decade in Russia, the incidence of scabies has been officially kept at the level of 18-45 cases per 100 thousand people. But it can be much higher, since people do not go to the doctor: they try to cope with the disease on their own or are ashamed of their symptoms.

Scabies agent

The cause of the disease is the scabies mite Sarcoptes scabiei, which feeds on flakes of dead skin. It spends most of its life in the skin, and appears on the surface only for mating.

The size of an adult tick is approximately 0.1 mm. The parasite has a powerful jaw, with the help of which it gnaws tunnels in the skin

As a rule, mating of ticks occurs in the evening. After it, the males die, and the females gnaw through human skin and make scabies in it, in which they lay 2-4 eggs. The hatched larvae come to the surface of the skin and penetrate into the hair follicles and flakes of the epidermis (upper layer of the skin). After a couple of days, they molt and become nymphs, and then they become adults, ready to mate.

Features of the scabies mite Sarcoptes scabiei:

• the tick quickly dies in the external environment: it is unable to absorb water from the air, therefore it dies from moisture deficiency;
• for the parasite, temperatures above 55 degrees are detrimental;
• adult females can penetrate the skin only in the most sensitive areas, and larvae – in any, due to their small size;
• is usually infected by females and larvae at the same time.

Ways of transmission of scabies

There are two ways of transmission of scabies – direct and indirect.

Direct infection with scabies occurs during close bodily contact. There are known cases of tick transmission from an infected person to a healthy person even during a strong handshake.

Indirect infection with scabies occurs without direct contact with an infected person. This can happen in a bathhouse, a hotel, an entrance and in other places where many people touch the same objects on which there are ticks.

Usually scabies is infected in orphanages, boarding schools, hostels, barracks, prisons – wherever people live in a large group.

The risk of contracting scabies is higher in places where people work and live in small groups

Incubation period for scabies

The incubation period for scabies depends on whether infection has occurred with adult scabies mite or its larvae.

When infested with larvae, the first symptoms may appear after 10-14 days – this is how long it takes for the mites to mature. And when infected with already fertilized females, there may not be an incubation period at all: the females will immediately begin to dig scabies and lay eggs in them in order to breed as soon as possible.

Types of scabies

Typical scabies – the most common, accompanied by excruciating itching, itching, nodules and blisters on the skin. The characteristic symptom of the disease – itching – usually appears 10-14 days after infection. Itching intensifies in the evening and at night, it is at this time that scabies mites are active.

For the treatment of typical scabies, scabicides are prescribed – drugs that destroy mites and their larvae. The illness usually resolves within 2-3 weeks.

Clean scabies mostly occurs in people who shower or bathe in the evening. They have almost no nodules and blisters on their skin, strong scratching and bloody crusts.

Treatment for clean scabies is the same as for typical scabies. With the right choice of drugs and compliance with all the doctor’s recommendations, recovery occurs in 2-3 weeks.

Norwegian (crustal) scabies is a rare and highly contagious form of the disease. It was first identified by Norwegian doctors in 1848 in patients with leprosy (leprosy).

As a rule, Norwegian scabies occurs in immunocompromised people, in patients with Down’s syndrome, HIV, dementia, oncological diseases, as well as in patients taking hormonal and cytotoxic drugs for a long time.

With Norwegian scabies, vesicles, nodules, cracks form on the skin, and then – rough crusts – gray-yellow or brown-black. Such crusts can, like a shell, cover large areas of the skin and prevent a person from moving normally. In the lower layers of the crusts, sinuous depressions are visible – scabies. When removing the crusts, extensive weeping erosions are exposed. Between the layers of crusts, a huge number of mites are found – up to 200 individuals in one square centimeter (for comparison: with typical scabies, there are usually no more than 10-15 of them).

Norwegian scabies can cause a microepidemic – when all family members, health workers and patients who are in the same room are infected with the disease.

Treatment of Norwegian scabies is long and takes place in two stages. First, the doctor removes the crusts from the patient’s skin (sometimes local anesthesia is required), then prescribes anti-scabies, which will need to be used for a long time.

Scabies without burrows is less common than typical and is usually found in people who have been in contact with people with scabies. With such scabies, infection with scabies mite larvae occurs. Symptoms of the disease: single nodules and inflammatory vesicles on the skin.

Scabies without burrows usually resolves in 2 weeks, is treated in the same way as typical scabies – with anti-scabies drugs.

Scabious lymphoplasia – manifested by intensely itchy flat rounded bluish-purple nodules, which are most often localized on the trunk (buttocks, abdomen, in the axillary region), as well as on the elbows and genitals in men, mammary glands in women. The basis of the disease is the reaction of the body to the waste products of the tick. This happens in people who suffer from scabies for a long time.

After full therapy, rashes may disappear in 2 weeks – 6 months.

Scabious erythroderma occurs in people who have been treated for a long time (up to 3 months) with typical scabies with corticosteroid ointments, antipruritic and soothing drugs. The disease is manifested by many itch moves that occur even in atypical places (between the shoulder blades, on the head, on the face). At the same time, itching is mild, and patients do not comb the skin, but rub it with their palms.

The treatment of scabious erythroderma is quite long – up to 6 weeks may be required until complete recovery.

Pseudosarcoptic mange is a type of scabies that affects dogs, pigs, horses, rabbits, wolves, foxes and other animals. Pseudosarcoptic mange can only be contracted from animals. It is not transmitted from person to person.

The incubation period is several hours. There are no scabies, since the mites do not breed on an unusual host and only partially burrow into the skin, causing itching. The rashes are concentrated on open areas of the skin and look like blisters, blisters, bloody crusts and scratches.

Pseudosarcoptic mange often resolves spontaneously after contact with the affected animal is stopped. If the symptoms recur or persist for several days, you should consult a doctor to make an accurate diagnosis.

Symptoms of scabies

The main symptom of scabies is unbearable itching, which intensifies in the evening and at night.

Itching runs along the burrows. They look like straight or curved lines that rise above the skin. The color of the lines can be dirty gray or whitish gray. Length – 5-7 mm.

Most often, itch moves are found on the wrists, feet, male genital organs, in the interdigital spaces.

The skin of a person infected with scabies usually has blisters and nodules. In about a third of cases, young males and females of the parasite are found in them. You can see them with the naked eye: ticks look like white or yellowish dots the size of a poppy seed.

Nodules with mites are located in the area of ​​hair follicles. Bubbles are more often between the fingers, on the wrists.

The main symptom of scabies is excruciating itching

Complications of scabies

Complications of scabies in the form of dermatitis and secondary pyoderma occur in approximately 50% of patients.

Dermatitis is an inflammation of the skin, which is manifested by redness, burning, tingling, itching, swelling of the affected area. Secondary pyoderma is a purulent-inflammatory skin disease caused by bacteria.

Less commonly, scabies develops microbial eczema – inflammation of the skin of an allergic nature caused by microbes.

Skin changes in scabies complicated by the addition of a secondary infection:

• staphylococcal impetigo – inflammation of the hair follicle caused by staphylococcus aureus;
• deep folliculitis – damage to the deep sections of the hair follicle, which leads to purulent inflammation;
• furunculosis – acute purulent-necrotic inflammation of the hair follicle, sebaceous gland and surrounding tissues;
• impetigo – vesicular-pustular rash;
• paronychia – inflammation of the periungual ridge.

Scabies in children

As a rule, children become infected with scabies in a direct way – through prolonged contact with the skin of an infected person. This happens when sleeping in the same bed, contact games, using shared toys. In addition, children can catch scabies in crowded groups – in orphanages, camps, hospitals, sports clubs, swimming pools. Teenagers are infected with scabies during sexual intercourse.

The course of scabies in children is usually more pronounced than in adults. Complications develop more often – microbial eczema, pyoderma (purulent-inflammatory skin lesions), impetigo (vesicle-pustular rashes), paronychia (inflammation of the periungual roller).

Symptoms of scabies in children:

• severe itching that worsens in the evening and at night;
• rash;
• scabies;
• nodules and vesicles on the skin.

Symptoms of scabies in children are usually worse than in adults

In infants and young children, rashes can be located on any area of ​​the skin – including the face, scalp, palms and soles. The rash in babies often begins to get wet, there are multiple grouped vesicles in the lesions, scabious lymphoplasia of the skin.

In school-age children and adolescents, scabies affects the hands, feet, elbows, buttocks, genitals, intergluteal folds.

Diagnosis of scabies

The diagnosis of scabies is made by a doctor – a dermatologist, therapist or infectious disease specialist – on the basis of an examination and complaints of the patient.

A clear sign of the disease is pruritus, which becomes unbearable in the evening and at night. Other symptoms that make it possible to suspect the disease are characteristic linear scratches and nodules on the skin.

Skin scrapings can confirm the diagnosis of scabies. However, it should be borne in mind that there may not be ticks in the biomaterial if the person has washed himself thoroughly before visiting the doctor.

Another way to detect a mite in a laboratory or clinic is to apply a drop of 40% lactic acid to the suspected itch, nodule, vesicle. Lactic acid loosens the epidermis well, and after a few minutes it can be carefully scraped off, placed on a glass slide and examined under a microscope.

The tick extraction method is also used. In this case, the doctor opens the blind end of the itch with a needle. The female is attached to the needle. Then the doctor takes the needle out of the itch along with the female and immerses it in a drop of water or 40% lactic acid. Then microscopy is performed.

Treatment of scabies

There are three ways to treat scabies: specific, prophylactic and trial.

Specific treatment is given to patients with symptoms of the disease and a clinically confirmed diagnosis. Scabicides are used – drugs that destroy the scabies mite and its larvae.

Preventive treatment is performed according to epidemiological indications – in scabies. However, people may not have symptoms.

Such treatment is indicated for everyone who has been in contact with an infected person: family members, sexual partners, nannies and nurses, members of close groups in orphanages, boarding schools, hostels, prisons, barracks.

Trial treatment is performed only in cases where the patient has symptoms of scabies, but the causative agent – scabies mite – is not detected. If after the use of anti-scabies drugs a positive effect occurs, then the diagnosis of “scabies” is considered confirmed.

Anti-scabies preparations

Ointments, emulsions, aerosols are used to kill scabies mites.

Basic scabicides – scabicides:

• preparations containing esdepalletrin, a neurotoxic insect poison. Contraindicated in pregnant women, as well as in patients with bronchial asthma and obstructive bronchitis;
• benzyl benzoate (ointment, emulsion): 20% for adults and 10% for children from 3 to 7 years;
• sulfuric ointment 33%. The drug is contraindicated in children under 3 years of age. Has an unpleasant smell, stains clothes. Possible skin irritation, longer treatment;
• permethrin 5% (emulsion). The drug is not recommended for use in children under 1 year old, patients with liver and kidney diseases, lactating women;
• crotamiton 10% (cream, lotion). Pregnant women can use the medicine only according to strict indications. In addition, the drug is contraindicated in children under 12 years of age.

The doctor prescribes the drug regimen. Self-medication can be hazardous to health.

General rules for the use of anti-scabies:

• apply drugs in the evening, with bare hands, not with a tissue or swab;
• carefully rub the preparations into the palms and soles;
• change underwear and bed linen after completion of the course;
• simultaneously treat everyone who is in the focus of infection.

The doctor may prescribe antihistamines or topical corticosteroids to relieve itching. Both of them are usually used in a short course.

If itching does not resolve within a week, it may be necessary to re-treat the skin with scabicide preparations after thoroughly washing the patient with soap and a washcloth.

Prognosis and prevention

With proper and timely treatment, the prognosis of scabies is favorable. The disease is cured in an average of 4-7 days, after which the doctor monitors the condition for 2-3 weeks. Residual itching may persist for another 10-14 days.

Basic measures to prevent scabies:

• treatment and dispensary observation of all people with scabies;
• elimination of scabies foci: disinfection of bed and underwear;
• regular preventive examinations of children and adults in hospitals, nursing homes, colonies, orphanages, etc.

Scabies – first signs, remedies

The skin disease caused by the scabies mite is called scabies. The condition is quite unpleasant, causes a lot of discomfort and is contagious. Everyone needs to know the symptoms of scabies mite infection – this will help to immediately begin treatment and prevent infection of everyone around.

How infection occurs

Infection with scabies through contact with a sick person is the most common route of infection. But this can also happen in contact with dishes, towels and any objects that the patient has touched. Roughly speaking, you can get scabies even after a trip on public transport, if you grab the handrails immediately after an infected person.

A female tick that gets on the skin begins to move along the stratum corneum and makes passages where it lays larval eggs. After a few days, adults emerge from the deposited larvae. The whole process from laying eggs to the appearance of sexually mature individuals takes a maximum of 14 days.

Knowing the movements of the scabies mite, one can understand what scabies looks like in adults – the skin has thin “strings” – passages, winding and slightly intermittent – this is the path along which the female moves. In other places, small dots-bites are noted.

How scabies manifests itself

In medicine, it is customary to distinguish between several types of the disease in question, which can give a different clinical picture. But any scabies can be manifested by itching and rash – these are the first signs of pathology. It is characteristic that the scabies mite is active at night, and the characteristic itching disturbs the patient’s sleep. The result is not only traces of scratching on the skin, but also irritability, bad mood.

Classically, scabies appears on the hands (between the fingers and on the elbows), on the abdomen, thighs, less often on the buttocks and neck.

There is a so-called ear scabies – the parasite settles in the auricles and the person suffers from severe itching, which cannot be relieved without the use of ear sticks / matches and other objects that are dangerous to the hearing organs. The initial stage of ear scabies will be accompanied by a slight itching on the hands, but rather quickly the parasite moves to the “place of permanent deployment.”

We should also mention Norwegian scabies – infection also occurs through contact with a sick person, but intense symptoms appear only against the background of low immunity, after paralysis, with some genetic diseases. Norwegian scabies after treatment requires restoration of hair and nails.

Diagnostic measures

As soon as the first signs of scabies appear on the body, you should seek qualified medical help. A dermatologist deals with this disease, he will also conduct diagnostics.

It is enough for a specialist to look at the areas of the body affected by the scabies mite, and he will be able to make an accurate diagnosis. In case of doubt, these areas are smeared with iodine – after drying, all moves will be shown by a brown line.

How to treat scabies

Medicines and ointments for the disease must meet the following requirements:

• destroy not only sexually mature parasites, but also their larvae;
• have minimal toxicity;
• be easy to use;
• do not stain clothes and skin so that the patient can lead a normal life.

Most often, doctors prescribe sulfuric ointment, crotamiton or permethrin solution – these agents are applied externally and can quickly destroy the scabies mite and its larvae. It is important to choose the right treatment for scabies in children – it must be absolutely non-toxic, hypoallergenic.

Regardless of which particular drug will be chosen for treatment, you need to know the rules for its use:

1. Treatment of affected areas of the body must be carried out in strict accordance with the scheme given by the doctor.
2. Absolutely the whole body is processed, special attention should be paid to the armpits, inguinal folds, popliteal fossae. The scalp is treated only in children, for adults this is not necessary.
4. Do not allow even a small amount of the drug to get into the eyes. If this happens, then you need to call the ambulance team and rinse your eyes with clean water before the arrival of specialists.
5. Any medicinal product must be applied by hand.

How to treat human scabies:

1. The first day – in the evening the infected person is washed in the shower with soap, wipes himself dry and treats the whole body with the selected preparation. Be sure to wear clean clothes and change bedding.
2. Second or third day – you can not take a shower and change underwear / bed linen.
3. Fourth day – take a shower with soap, apply the drug to the skin, change clothes and bedding.
4. Fifth day – the patient washes in the shower, changes linen and clothes.

Please note: many are interested in the question “how to get rid of scabies on the hands.” Such localization of the disease does not mean that only the affected areas can be treated – the scabies mite can simply go to another place.

After the end of the treatment, you should visit a dermatologist for a follow-up examination. This is usually done on the tenth day after the start of therapy, and the indicator of recovery will be absent scabies, itching and scratching on the skin.

Preventive measures

Causes and prevention of scabies go hand in hand. After all, you can get infected only by contact with an already infected person or objects after using it, therefore, for prevention, experts recommend washing your hands as often as possible, it is advisable to wipe them with a liquid antiseptic. Chlorhekisdin will be an excellent option – a convenient bottle can easily fit in a purse or glove compartment of a car, and washing your hands several times a day will be an excellent prevention of scabies.
