Dengue Fever and Dengue Hemorrhagic Fever 2003

Dengue fever and dengue hemorrhagic fever (DHF), two of the most important arboviral diseases of humans, occur in most tropical areas of the world. The disease is caused by one of four virus serotypes (DEN-1 through DEN-4) of the genus Flavivirus. The primary vector, the Aedes aegypti mosquito, is rarely seen in Indiana. However, another competent vector, Aedes albopictus, has been seen in at least 37 Indiana counties.

In 2003, one case of dengue fever was reported in Indiana. For the five-year period 1999-2003, only four cases of dengue fever were reported in Indiana. All four cases were acquired while traveling overseas to tropical and subtropical areas.
