Transmission of Dengue VECTOR: Transmitted to

humans by bite of female aedes aegypti mosquito. Dengue mosquitos lay eggs in areas with water (see left)

HOST: Humans become host of virus. Virus incubation is 4-10 days then produce dengue symptoms

TRANSMISSION: Humans get infected from bite of infected aedes mosquito. Mosquitos get infected when they bite infected humans.
