Dengue: Symptoms, Prevention and Treatment

Dengue is a mosquito-borne disease transmitted by female mosquitoes mainly of the species Aedes aegypti or A.albopictus. There are 4 distinct, but closely related, serotypes of the virus that cause dengue (DEN-1, DEN-2, DEN-3 and DEN-4).  After virus incubation for 4–10 days, an infected mosquito is capable of transmitting the virus for the rest of its life. Patients infected with the dengue virus can transmit the infection via Aedes mosquitoes after their first symptoms appear.


High fever  accompanied by bad headache, pain behind eyes, muscle & joint pains, nausea, vomiting, swollen glands or rash. Severe dengue is a deadly complication due to plasma leaking,fluid accumulation, respiratory distress,severe bleeding, or organ impairment.

Dispose solid waste properly and remove artificial man-made habitats 
Personal household protection like window screens,long-sleeved clothes, insecticide treated materials,coils, vaporizers
Apply insecticides during outbreaks as one of the emergency vector-control measures. 
Self-treatment should be avoided. Consult a specialist if you have any such symptoms.
