The most common symptoms of Zika virus infection are fever, rash, joint pain, and conjunctivitis (red eyes). Symptoms typically begin 2 to 7 days after being bitten by an infected mosquito. Residents that traveled recently and experience symptoms common of Zika infection should go to their healthcare provider.
About 1 in 5 people infected with Zika will get sick. For people who get sick, the illness is usually mild with symptoms lasting from several days to a week. For this reason, many people might not realize they have been infected. Severe disease is uncommon.
