Dengue and Its Prevention
Dengue fever is a disease caused by a family of viruses that are transmitted by mosquitoes.

Manifestations include headache, fever, rash, and evidence of hemorrhage in the body.

The transmission of the virus to mosquitoes must be interrupted to prevent the illness. To this end, patients are kept under mosquito netting until the second bout of fever is over and they are no longer contagious.
