Some people who are infected with the Zika Virus 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.

Travelers to areas with ongoing Zika virus transmission should monitor for symptoms or illness upon return. If they become sick, they should tell their healthcare professional where they have traveled and when.

Pregnant women:

  • Consider postponing travel to any area where Zika virus transmission is ongoing.

  • If you must travel to or live in one of these areas, talk to your healthcare provider first and strictly follow steps to prevent mosquito bites.

  • If you have a male partner who lives in or has traveled to an area where Zika transmission is ongoing, either abstain from sex or use condoms consistently and correctly for the duration of your pregnancy.

Women trying to get pregnant:

  • Before you or your male partner travel, talk to your healthcare provider about your plans to become pregnant and the risk of Zika virus infection.

  • You and your male partner should strictly follow steps to prevent mosquito bites.

Mosquitoes that spread Zika are aggressive daytime biters. They also bite at night. There is no vaccine or medicine available for Zika virus. The best way to avoid Zika virus infection is to prevent mosquito bites. Specific areas where Zika virus transmission is ongoing are often difficult to determine and are likely to continue to change over time.
