Dengue is a viral infection transmitted to humans through the bite of infected Aedes mosquitoes.
Dengue is widespread throughout the tropics, with local variations in risk influenced by climate parameters as well as social and environmental factors. Dengue is caused by a virus of the Flaviviridae family and there are four distinct, but closely related, serotypes of the virus that cause dengue (DENV-1, DENV-2, DENV-3 and DENV-4).
All 4 dengue serotypes exist in Nepal, with DENV-1 and 2 historically contributing the highest burden, according to the EDCD.
