Keep on spraying! Some travelers to areas with ongoing Zika virus transmission will become infected while traveling but will not become sick until they return home and they might not have any symptoms. In fact, 4 out of every 5 people with Zika don't become ill at all. To stop the spread of Zika, all travelers from Zika infected countries should use insect repellent for three weeks after travel to prevent mosquito bites.
Most people who are infected do not have any symptoms. People who do have symptoms have reported fever, rash, joint pain, and red eyes. Other commonly reported symptoms include muscle pain and headache. The illness is usually mild with symptoms lasting from several days to a week. Severe disease requiring hospitalization is uncommon and the number of deaths is low. Travelers to areas with ongoing Zika virus transmission should monitor for symptoms or illness upon return. If they become sick, they should tell their doctor/NP/PA where they have traveled and when.
