Dengue Fever
Life Cycle of Dengue Virus

May 2012
The life cycle of dengue virus is strictly dependent on only mosquitoes and humans. Once the mosquito feeds on a viremic human, there is a 10-day extrinsic incubation period in which the virus develops and passes from the mosquito intestinal tract to its salivary glands.
Human infection results from the bite of the infected mosquito.
The mosquito remains infectious for its entire 1-month life, and can transmit infection with as few as 100 viral particles.
Mosquito eggs actually can survive desiccation for several months, and repopulation will occur once they are rehydrated.
