Zika Virus Transmission: The virus passes from an (1) infected human to a mosquito (2) to an uninfected human. Aedes aegypti Lifecycle: A mosquito begin its life as an (a) egg, then develops into a (b) larva, then a (c) pupa, then an (d) adult. Adult females feed on humans, potentially (e) becoming infected with the Zika virus and then (f) infecting humans with the virus. After feeding and mating, the female (g) lays eggs of her own.
Timeline of Aedes aegypti Lifecycle: An egg can survive in dry conditions for several months, but in the presence of water it will hatch into a larva in 2 to 4 days. The larva will develop further for around 4 days until it becomes a pupa. After 2 days, the adult mosquito emerges from the pupa. This development process can be completed in 8 days, but may take up to 3 weeks in less favorable conditions. The adult lives 2 to 4 weeks and will fly an average of 400 meters.
