Zika Virus Zika virus is transmitted to people primarily through the bite of an infected Aedes species mosquito -- Aedes aegypti, shown here, and Aedes albopictus. The same mosquitoes spread dengue and chikungunya viruses. The mosquitoes typically lay eggs in and near standing water in things like buckets, bowls, animal dishes, flower pots and vases. They prefer to bite people and live indoors and outdoors near people. Mosquitoes that spread chikungunya, dengue, and Zika are aggressive daytime biters, but they can also bite at night. Mosquitoes become infected when they feed on a person already infected with the virus. Infected mosquitoes can then spread the virus to other people through bites.
