The pregnant mother is infected with Zika virus often gives birth to a child having microcephaly (head is smaller than expected) and the abnormal developed brain. Aedes Aegypti mosquito is considered as the culprit spreading Zika virus.
Aedes Aegypti is a very small mosquito type without venom. It can bite humans in daytime without causing pain. The danger is Aedes Aegypti contains Zika virus that has ability to recognize the smell of human rapidly and like sucking human blood. Infected Zika mosquitos often live under the floor, furniture, dark areas, especially in small puddles in bonsai pots and houseplants. According to Joe Conlon- a spokeman of American Mosquito Control Association, Aedes mosquito may proliferate with a very small amount of water, for example they can lay their eggs in soda drink bottle caps or fast food bags that people throw away.
