Dengue: Symptoms and Complications

Dengue fever is a disease caused by the bite of Aedes mosquito that usually attacks during day time. The preferred spots of these mosquitoes to bite are below the elbow and below the knee. It is also known as Break Bone fever or DANDY fever. We talk in the article about the Symptoms and Complications of the Dengue virus.

These mosquitoes can’t breed once the temperature falls below 20 degrees. These mosquitoes are typically active during the time period of July to November. The peak time for this disease is September and October. Rarely, it has been seen in the winter and summer season.
