Dengue fever is a viral infection transmitted to humans through the bite of an infected Aedes mosquito. Dengue is spread 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 family Flaviviridae and there are four distinct, but closely related, virus serotypes, which cause dengue (DENV-1, DENV-2, DENV-3, and DENV-4). Recovery from infection is believed to provide lifelong immunity to this serotype. However, cross-immunity to other serotypes after recovery is only partial and temporary. Subsequent infection (secondary infection) of other serotypes increases the risk of developing severe dengue.

All four dengue serotypes are found in Nepal, with DENV-1 and 2 historically contributing the greatest burden.
