Dengue Virus

Dengue is an arthropod-borne virus (arbovirus) caused by one of any four related viruses: DENV 1, DENV 2, DENV 3, and DENV 4. Dengue is found in Asia, Africa, Central and South America, the Pacific Islands and the Caribbean. About one in four people with dengue get sick, and symptoms can range from mild to severe. Dengue is transmitted via the bite of an infected mosquito of the genus Aedes, namely Aedes aegypti and Aedes albopictus. These mosquitoes can be found worldwide, in both tropical and subtropical regions.

Although established populations of Aedes aegypti have not been found in Indiana, Aedes albopictus can be found in the southern two-thirds of the state. Dengue is not found in Indiana mosquitoes. Indiana has cases of dengue every year in travelers returning from parts of the world where dengue is found.
