Unfortunately, this mosquito is adapted to the urban environment. Eggs deposited on the internal walls of any kind of containers can contain artificial water.
Themosquito Aedes aegypti and some other species transmit the virus to humans. Aedes aegypti is found in tropical and subtropical parts of South America, parts of the Caribbean, and Africa (not Asia). Apart frommosquitoes, the only other known hosts of the virus are primates and humans.
