Dengue fever is a viral infection transmitted by the Aedes mosquito and is prevalent in many tropical and subtropical regions. As the dengue season approaches, it's important to be aware of the symptoms, preventive measures, and available treatments.

What is Dengue Fever?

Dengue fever is a viral illness caused by the dengue virus and is characterised by flu-like symptoms. The virus is primarily transmitted to humans through the bite of infected Aedes mosquitoes, particularly Aedes aegypti. These mosquitoes are active during the day, and their breeding sites include stagnant water sources.

Common Symptoms of Dengue Fever:

1. High fever (over 101°F or 38.5°C)
2. Severe headache and eye pain
3. Joint and muscle pain
4. Skin rash
5. Nausea and vomiting
6. Fatigue and weakness

Prevention Measures:

Preventing dengue fever involves minimizing mosquito breeding sites and protecting yourself from mosquito bites. Here are some effective prevention strategies:
1. Eliminate stagnant water sources, such as empty containers and flowerpots, where mosquitoes breed.
2. Use mosquito repellents containing DEET on exposed skin.
3. Wear long-sleeved shirts, long pants, and socks to cover exposed areas.
4. Install window screens and use bed nets treated with insecticides.

Diagnosing Dengue Fever:

If you experience symptoms of dengue fever or suspect you may have been exposed to the virus, it's important to seek medical attention. Healthcare professionals can perform tests, such as a blood test, to confirm the diagnosis.

Platelet Counts in Dengue Fever: Significance and Monitoring

Platelet counts are crucial in dengue fever as the virus affects platelet production and function, resulting in decreased levels. Here, we explore the role of platelet counts in diagnosis and treatment. Seek medical attention promptly if experiencing dengue symptoms. Remember, platelet counts are just one aspect of comprehensive dengue management.

Platelet Counts and Dengue Fever:

Dengue fever can cause thrombocytopenia, a decrease in platelet counts, which may lead to bleeding manifestations. Monitoring platelet levels helps identify disease severity and potential bleeding risks.

Platelet Monitoring:

Regular platelet count monitoring through blood tests, such as a complete blood count (CBC), is essential to track dengue progression and guide treatment decisions.

Platelet Transfusion:

In severe cases with significantly low platelet counts or bleeding complications, platelet transfusion may be necessary. However, it is reserved for critical cases and determined by medical professionals based on specific guidelines.

Platelet Recovery:

Platelet counts typically begin to recover as the dengue infection resolves. Adequate rest, hydration, and symptomatic treatment support platelet recovery.

Dengue Treatment:

Currently, there is no specific antiviral medication for dengue fever. Treatment focuses on relieving symptoms and managing complications. It is crucial to rest, drink plenty of fluids, and take over-the-counter pain relievers under medical supervision. In severe cases, hospitalisation may be necessary.

Complications and Warning Signs:

Dengue fever can progress to a severe form known as dengue hemorrhagic fever or dengue shock syndrome. Warning signs include severe abdominal pain, bleeding gums, persistent vomiting, rapid breathing, and fatigue. Seek immediate medical attention if you experience any of these symptoms.


By understanding the symptoms, preventive measures, and available treatment options for dengue fever, you can protect yourself and your loved ones. Remember to stay vigilant during the dengue season and take necessary precautions to minimize the risk of mosquito bites. If you suspect you have dengue fever or experience severe symptoms, consult a healthcare professional for appropriate diagnosis and care.
