Dengue Virus

Group: Group IV ((+)ssRNA)
Family: Flaviviridae
Genus: Flavivirus
Species: Dengue virus

• Dengue (DF) and dengue hemorrhagic fever (DHF) are caused by one of four closely related, but antigenically distinct, virus serotypes (DEN-1, DEN-2, DEN-3, and DEN-4), of the genus Flavivirus.
• Infection with one serotype does not protect a person against infection with another.
• Aedes aegypti, a domestic, day-biting mosquito that prefers to feed on humans, is the most common Aedes species.(Unlike the mosquitoes that cause malaria, dengue mosquitoes bite during the day.)
• Dengue viruses occur in most tropical areas of the world.
• Dengue is most common in cities but can be found in rural areas.
• Incubation Period: averages 4 to 6 days, with a range of 3 to 14 days.
