Transmission of Zika
Transmission is primarily by bites from infected female mosquitoes of the genus Aedes: A. aegypti, and to a lesser degree A. albopictus (known as the tiger mosquito). These mosquitoes are mainly present in urban environments during the day.
These mosquitoes can also transmit other viruses, such as dengue or chikungunya. They tend to bite throughout the whole day, although they are most active during early morning and late afternoon. Although these mosquitoes can be found in any environment, they are common in urban residential areas and their surroundings.
There are other possible ways of transmitting zika:
Sexual.
Maternal-foetal during pregnancy.
Through blood: blood transfusion or organ transplant.
