Zika virus (Zika) is transmitted to humans through mosquito bites, causing an illness that is usually mild and can last from several days to a week. Severe disease requiring hospitalization is uncommon. Symptoms include fever, rash, joint pain, and red eyes, though many people infected with Zika do not have symptoms. There is currently no vaccine to prevent the disease.
Travelers to affected areas are advised to understand the risks and preventative measures before traveling. Pregnant women should not travel to areas with Zika outbreaks.
