Dengue Fever


Dengue Fever Symptoms, Causes, Diagnosis, Treatment:

Dengue fever is a mosquito-borne viral infection that is commonly found in tropical and subtropical regions around the world. It is caused by the dengue virus, which is transmitted to humans through the bites of infected female mosquitoes, primarily the Aedes aegypti mosquito.

Dengue fever is a mosquito-borne viral infection that is prevalent in tropical and subtropical regions. Let’s delve into its symptoms, causes, diagnosis, and treatment:


What are the Symptoms Dengue Fever?

  1. High fever (typically lasting 2 to 7 days)
  2. Severe headache, often behind the eyes
  3. Joint and muscle pain
  4. Rash (typically appearing after a few days)
  5. Nausea and vomiting
  6. Mild bleeding from the nose or gums
  7. Fatigue and weakness

What are the Causes Dengue Fever?

It is caused by any of the four dengue virus serotypes (DEN-1, DEN-2, DEN-3, DEN-4), which are transmitted to humans through the bites of infected Aedes mosquitoes, primarily Aedes aegypti. These mosquitoes become infected by biting a person with dengue virus in their bloodstream.

How to Diagnosis Dengue Fever?

To diagnose dengue, healthcare providers may consider the following:

  1. Symptoms and medical history
  2. Physical examination
  3. Blood tests, such as the detection of dengue viral antigens or antibodies or PCR tests to identify the virus’s genetic material

Treatment for Dengue Fever:

  1. Supportive care: Rest, hydration, and over-the-counter pain relievers (e.g., acetaminophen) to reduce fever and pain.
  2. Avoiding certain medications: Aspirin and non-steroidal anti-inflammatory drugs (NSAIDs) should be avoided, as they can increase the risk of bleeding.
  3. Hospitalization: Severe cases, such as dengue hemorrhagic fever or dengue shock syndrome, may require hospitalization for close monitoring, intravenous fluids, and other supportive measures.

How to Prevent Dengue Fever?

  1. Mosquito control: Eliminate stagnant water where mosquitoes breed, use insecticides or larvicides, and use mosquito nets or screens.
  2. Personal protection: Wear protective clothing, use mosquito repellents, and sleep under mosquito nets, especially during peak mosquito activity times.
  3. Vaccination: In some countries, a dengue vaccine is available. Consult with healthcare professionals regarding its availability and suitability.
