Brazil Battles Dengue Fever Outbreak

A recent outbreak of Dengue fever, a common disease in the tropics has affected an estimated 250000 persons and killed 17 in Sao Paolo, Brazil. The government says cases of the mosquito-borne disease have shot up 162 percent so far this year.

Dengue fever is a disease caused by a family of viruses that are transmitted by mosquitoes. The presence of fever, rash, and headache (the "dengue triad") is characteristic of dengue fever.

In some cases the disease develops into the life-threatening dengue hemorrhagic fever, resulting in bleeding, low levels of blood platelets and blood plasma leakage, or into dengue shock syndrome, where dangerously low blood pressure

The disease is transmitted by the bite of an infected mosquito and is not contagious, so the best mode of prevention is to prevent being bitten by an infected mosquito.

Because dengue fever is caused by a virus, there is no specific medicine or antibiotic to treat it. For typical dengue fever, the treatment is directed toward relief of the symptoms (symptomatic treatment) and includes adequate rehydration.
