Acne Dengue Fever Dengue Fever exists throughout tropical and subtropical areas of Africa, Asia, the Americas, Australia and the South Pacific. Dengue is transmitted to humans by the bite of infected Aedes aegypti, and less commonly, Ae.albopictus and Ae.scutellaris mosquitoes. In contrast to some of the anopheline mosquitoes that transmit malaria, Aedes sp. are well adapted to urban environments where they breed in containers of clean water around the houses. This makes the disease more common in urban settings than in rural settings. The incubation period is usually 5-8 days.
Dengue fever is characterized by acute onset of fever, chills, headache, eye pain and back ache.
A transient, generalized erythematous sometimes occurs in the first 24-48 hours. This is followed by a wide spectrum of manifestations including body aches, fatigue, nausea, vomiting and respiratory symptoms. On the third to fifth day the fever diminishes and a rash appears on the trunk and often spreads to the face and extremities. There may also be petechiae and bloody nose. This is characterized by petechiae, thrombocytopnia, and evidence of hemoconcentration.
