It is primarily transmitted through the bite of infected Aedes mosquitoes, particularly Aedes aegypti and Aedes albopictus.
In addition to being transmitted from a pregnant woman to her fetus during pregnancy, Zika can be passed on through sexual contact, blood transfusion, and organ transplantation.
Symptoms for those who do experience them usually appear within 3-7 days of being infected and can include fever, rash, joint pain, red eyes (conjunctivitis), headache, muscle pain and fatigue.
