What are the causes, symptoms, treatments, and prevention methods for dengue fever?

Hi,

Welcome to icliniq.com.

I read your query.

Dengue fever is a viral infection transmitted by the Aedes mosquito, primarily the Aedes aegypti species. It is caused by any one of four closely related dengue viruses (DEN-1, DEN-2, DEN-3, and DEN-4), which are members of the Flaviviridae family. These viruses are transmitted to humans through the bite of infected Aedes mosquitoes. Symptoms may appear four to ten days after the mosquito bite and include:

1. High fever.
2. Severe headache.
3. Pain behind the eyes.
4. Joint and muscle pain.
5. Nausea and vomiting.
6. Rash.
7. Mild bleeding (such as nosebleeds, gum bleeding, or easy bruising).

A severe form of dengue known as dengue hemorrhagic fever is seen in fewer people, typically due to secondary infections and other genetic and immunological factors. Treatment for dengue focuses on symptom management since there is no specific antiviral medicine:

1. For pain, use Paracetamol (avoid Ibuprofen and Aspirin, which can increase the risk of bleeding).
2. Ensure plenty of fluids to prevent dehydration.
3. Consider IV (intravenous) fluids if necessary.
4. Papaya extract tablets (Tablet Caripill) can also be used.

Preventive measures include:

1. Mosquito control: Eliminate standing water around homes and communities where mosquitoes breed.
2. Use mosquito nets, screens on windows and doors, and insect repellents containing DEET (N,N-diethyl-meta-toluamide), picaridin, or oil of lemon eucalyptus.
3. Wear protective clothing.
4. Avoid travel to high-risk areas.
5. Support community-based efforts to control mosquito populations, such as fogging and spraying insecticides in areas with high mosquito activity.

I hope this information helps you.

Thank you.
