Symptoms typically begin 2 to 7 days after being bitten by an infected mosquito. Illness is usually mild with symptoms lasting several days to a week.
Zika is primarily transmitted through the bite of infected Aedes mosquitoes.
Zika can also be transmitted from a pregnant mother to her baby during pregnancy or around the time of birth.
