When does dengue fever typically cause itching. How can you prevent mosquito bites to avoid dengue. What are the warning signs of severe dengue that require immediate medical attention. How long do itchy rashes from dengue usually last.

Understanding Dengue Fever: A Global Health Concern

Dengue fever is a mosquito-borne viral infection that affects millions of people worldwide each year. According to estimates, approximately 400 million individuals are infected annually, with about 100 million developing symptoms. This disease has become a significant public health issue, with outbreaks occurring across various regions, including Southeast Asia, the Western Pacific, the Eastern Mediterranean, the Americas, the Caribbean, and Africa.

What makes dengue fever so concerning? The virus is primarily transmitted through the bites of infected Aedes mosquitoes, particularly Aedes aegypti. These mosquitoes are widespread in tropical and subtropical regions, making dengue a persistent threat in many parts of the world.

Recognizing Dengue Fever Symptoms: From Mild to Severe

Identifying dengue fever early is crucial for proper management and preventing complications. The most common symptoms include:

• Fever
• Headache
• Eye pain (typically behind the eyes)
• Muscle, joint, or bone pain
• Rash
• Nausea and vomiting

How long do dengue fever symptoms typically last? In most cases, symptoms persist for about 2-7 days. However, some individuals may experience lingering fatigue and weakness for several weeks after the initial infection.

Warning Signs of Severe Dengue

While many dengue cases are mild, some can progress to severe dengue, which is a medical emergency. It’s crucial to recognize the warning signs, which include:

• Stomach or belly pain and tenderness
• Persistent vomiting (at least 3 times in 24 hours)
• Bleeding from the nose or gums
• Vomiting blood or blood in the stool
• Feeling unusually tired, restless, or irritable

What should you do if you notice these warning signs? Seek immediate medical attention at a local clinic or emergency room. Prompt treatment can be life-saving in cases of severe dengue.

Preventing Dengue: Effective Strategies to Avoid Mosquito Bites

Given that there’s no specific treatment for dengue fever, prevention is key. The most effective way to prevent dengue is by avoiding mosquito bites. Here are some strategies to consider:

Use EPA-Registered Insect Repellents

What are the most effective insect repellents for preventing dengue? The Environmental Protection Agency (EPA) recommends repellents containing the following active ingredients:

• DEET
• Picaridin (known as KBR 3023 and icaridin outside the US)
• IR3535
• Oil of lemon eucalyptus (OLE)
• Para-menthane-diol (PMD)
• 2-undecanone

How can you choose the right insect repellent? The EPA provides a search tool to help you find the most suitable repellent based on your specific needs and preferences.

Wear Protective Clothing

Covering your skin can significantly reduce the risk of mosquito bites. What clothing choices are most effective?

• Long-sleeved shirts
• Long pants
• Socks and closed-toe shoes

For added protection, consider treating your clothing and gear with 0.5% permethrin or purchasing pre-treated items.

Control Mosquitoes In and Around Your Home

Reducing mosquito populations in your living environment is crucial for dengue prevention. What steps can you take to control mosquitoes?

• Eliminate standing water where mosquitoes can breed
• Use window and door screens
• Use air conditioning when possible
• Keep your yard well-maintained and free of debris

Dengue Vaccination: Limited Availability and Specific Guidelines

While a dengue vaccine exists, its use is currently limited. What are the guidelines for dengue vaccination?

The dengue vaccine is only approved for use in children aged 9-16 years who have laboratory-confirmed evidence of a previous dengue virus infection and live in areas where dengue is common. In the United States, this includes:

• U.S. territories of American Samoa
• Puerto Rico
• U.S. Virgin Islands
• Freely associated states, including:
  • Federated States of Micronesia
  • Republic of Marshall Islands
  • Republic of Palau

Why is the vaccine not more widely available? The vaccine can potentially increase the risk of severe dengue in individuals who have never been infected with dengue virus before. Therefore, its use is carefully restricted to those who have already had a confirmed dengue infection.

Managing Dengue Fever: Dealing with Itchy Rashes

One of the most uncomfortable symptoms of dengue fever can be the itchy rash that often develops. When does this itching typically occur?

In many cases, the itchy rash appears as the fever subsides, particularly on the palms of the hands and soles of the feet. This rash is often described as dense and itchy, covering large areas of the body.

Why Does Dengue Cause Itching?

The itching associated with dengue fever is likely caused by several factors:

• Viral effects on the skin
• The body’s immune response to the virus
• Reabsorption of extracellular fluid into the blood during recovery
• Healing of skin tissues affected by the rash

In some cases, itching may also be related to liver complications caused by the dengue virus, such as acute hepatitis or elevated bilirubin levels.

Duration of Itchy Rashes

How long do dengue-related itchy rashes typically last? The duration can vary, but in most cases:

• Itching symptoms usually subside within 2-3 days
• Some cases may persist for about a week
• In rare instances, itching can continue for several weeks

Coping Strategies for Dengue-Related Itching

While the itching from dengue fever can be intense, there are several strategies to manage this symptom:

1. Use cool compresses to soothe itchy skin
2. Apply calamine lotion or other anti-itch creams
3. Take antihistamines to reduce itching (consult with a healthcare provider first)
4. Wear loose, breathable clothing to minimize skin irritation
5. Keep your nails short to prevent skin damage from scratching
6. Stay hydrated to support skin health

When should you seek medical attention for dengue-related itching? If the itching is severe, persistent, or accompanied by other concerning symptoms, it’s best to consult with a healthcare provider. They can assess your condition and recommend appropriate treatments.

Traveling to Dengue-Endemic Areas: Essential Precautions

If you’re planning to travel to regions where dengue is common, taking extra precautions is crucial. What steps should you take before and during your trip?

1. Research your destination:
   • Check for current dengue outbreaks or travel notices
   • Understand the local mosquito season and peak transmission times
2. Pack appropriately:
   • Bring EPA-registered insect repellents
   • Pack long-sleeved shirts and long pants
   • Consider permethrin-treated clothing or gear
3. Choose accommodations wisely:
   • Opt for places with air conditioning or reliable window and door screens
   • Consider using a bed net if sleeping arrangements are exposed to mosquitoes
4. Stay vigilant during your trip:
   • Apply insect repellent regularly, especially during peak mosquito hours
   • Avoid areas with standing water or known mosquito breeding sites
5. Monitor your health:
   • Be aware of dengue symptoms
   • Seek medical attention promptly if you develop a fever or other concerning symptoms

How long after returning from a dengue-endemic area should you monitor your health? It’s recommended to watch for symptoms for at least two weeks after your return, as this covers the typical incubation period for dengue virus.

The Future of Dengue Prevention and Control

As dengue continues to be a global health challenge, researchers and public health officials are working on various fronts to improve prevention and control measures. What are some promising areas of development?

• Vaccine research: Scientists are working on developing more broadly effective and safer dengue vaccines.
• Vector control: New technologies for mosquito control, including genetic modification approaches, are being explored.
• Improved diagnostics: Efforts are underway to create faster, more accurate diagnostic tests for dengue.
• Climate change mitigation: Understanding and addressing the impact of climate change on mosquito populations and dengue transmission patterns.
• Community engagement: Enhancing public awareness and participation in mosquito control efforts.

How can individuals contribute to these efforts? Staying informed about dengue, supporting local mosquito control programs, and participating in community health initiatives can all play a role in reducing the global burden of dengue fever.

In conclusion, while dengue fever remains a significant health concern, understanding its symptoms, taking preventive measures, and knowing how to manage its effects can greatly reduce its impact. By staying vigilant and informed, we can all contribute to the fight against this challenging disease.

When does itch when dengue fever usually occur?

This is an automatically translated article.

The article is professionally consulted by MSc Nguyen Thi Ngoc – General Doctor, General Health Examination Unit, Vinmec Central Park International General Hospital.

In many cases, patients with dengue fever develop an itchy rash when the fever stops, especially on the palms and soles of the feet. So when does the itch caused by dengue fever usually occur and how to overcome it?

1. Is dengue fever itchy?

Dengue fever patients experiencing itching is most likely a symptom caused by a virus. Accordingly, dengue fever often presents with typical signs in both severe and mild forms, including headache, dizziness, nausea and vomiting, diarrhea, skin rash, and dense itchy rash all over the body. body. There is a case where a patient with dengue fever has an itchy rash, so uncomfortable that they have to stay up all night, tired during the day, and can’t sleep because of itching everywhere. For some people, itchiness may even appear after new episodes of fever. This shows that the patient is in the recovery phase after the disease.
The cause of the itchy rash when dengue fever is because the body is in the process of reabsorption of extracellular fluid into the blood and in the skin tissue is recovering from the wounds caused by the rash, resulting in itching. .
On the other hand, clinically, dengue fever patients with itching may be caused by acute hepatitis caused by Dengue virus (Dengue hemorrhagic fever is often accompanied by enlarged or small liver, elevated SGOT and SGPT liver enzymes, elevated bilirubin levels, leading to mucosal jaundice). In this case, the patient may experience itchy skin due to biliary hyperpigmentation or acute liver failure due to drug use (eg, paracetamol overdose) leading to jaundice, itching as well as confusion. clotting factor disorder.
Usually, the itching symptoms when recovering from dengue fever will go away after a period of 2 to 3 days, in some cases it can take longer, about 1 week, or even up to several weeks.

2. Overcome the itchy situation of Dengue hemorrhagic fever

In general, if the platelet count gradually increases to stable and the patient no longer presents with fever, there is nothing to worry about. The treatment of dengue fever with itching is also nothing special. Patients can take Vitamin C to help strengthen their resistance, combined with adequate nutrition and reasonable rest. Besides, the patient should drink a lot of water every day, eat a light diet, should not eat fatty foods. To prevent allergies, patients should limit foods that cause severe allergies, such as seafood, beef, bush meat or foods to which the patient’s body is already allergic.
According to the advice of specialists, in case the itching is too much, causing discomfort and affecting daily activities, the patient should go to a medical facility for examination to be prescribed appropriate medication. Accordingly, the physician may consider giving the patient an antihistamine to help relieve itching, or an anti-allergy medication (eg, Loratadine). Usually, the dosage of the drug for adults and children will be different. On the other hand, depending on the patient, the doctor will choose an appropriate drug. For example, during the examination, the doctor will determine a number of factors related to the patient’s location and life in order to choose drugs and limit unwanted effects.

Charlotte Elton • Last updated: 10/03/2023

Last year, several outbreaks of dengue were recorded on the island. Spanish health authorities have warned that there is a “moderate” risk of being infected with the virus this summer as well.

Ibizan health officials have urged tourists to beware of dengue fever.

From May to November last year, there were several outbreaks of dengue on the island. The virus is carried by mosquitoes.

There is still a “moderate” risk that tourists could be infected with the virus this summer, health authorities warn.

What are the symptoms to watch out for and how can you protect yourself?

How many tourists got dengue in Ibiza last year?

Dengue fever is spread by mosquitoes that carry the virus. This disease is common in areas with hot and humid climates. It is not contagious and is not transmitted from person to person.

Six German tourists contracted dengue in Ibiza between May and November last year. A 27-year-old woman, her partner and their 13-month-old daughter were infected in August 2022. Another family – a 37-year-old woman, her partner and their nine-year-old son – allegedly contracted the virus in the same city in October 2022.

The risk of contracting the virus is currently low, but will increase to moderate in summer.

“One of the potential vectors of dengue is the Aedes albopictus mosquito, which is distributed throughout the Spanish Mediterranean and the Balearic Islands, as well as in some inland and northern regions of the country” , a spokesman for the Spanish Ministry of Health said.

“After learning about these cases, the authorities of the Balearic Islands took action: surveillance and control of vectors are carried out, public information is being carried out” , – said the representative of the department.

Ibiza is famous for its white sand beachesCanva

What are the symptoms of dengue fever?

Approximately 100 million cases of dengue fever are reported each year. Three-quarters of people who catch dengue fever are asymptomatic.

Infected individuals may experience mild or severe symptoms, including fever, nausea and vomiting, and rash. Joint, muscle, and eye pain are also warning signs.

Symptoms appear between four and ten days after the mosquito bite. If you suspect you have a virus, see your doctor as soon as possible.

Although most people recover without treatment in about a week, about one in 20 people may develop severe symptoms. In this case, you should immediately go to the emergency room. The risk is increased for those who have previously been infected with the virus.

Abdominal pain, vomiting of blood, bleeding from the nose or gums are symptoms of severe dengue.

How can you protect yourself from dengue?

There is a dengue vaccine approved for use in the European Union, but it is only recommended for people who have had dengue once.

The best way to prevent infection is to avoid mosquito bites. Wear long sleeves, use repellent, and sleep under a mosquito net.

Where is dengue found in Europe?

Dengue fever is very common in tropical and subtropical areas, but relatively rare in Europe.

During the summer months it has been found in the following European countries:

• Croatia

• France

• Italy

• 9 0002 Spain

• Portugal

Due to global warming, the virus is likely to will spread further north.
