Zika Travel Recommendations by Traveler Type and Country Category

Know before you go! Zika continues to be a problem in many parts of the world. There is no vaccine to prevent infection. Zika is spread mostly by the bite of an infected Aedes species mosquito (Ae. aegypti and Ae. albopictus). Zika can be passed from a pregnant woman to her fetus. Infection during pregnancy can cause certain birth defects.

Your decision to delay or cancel travel is personal and complex. In making this decision, consider your travel destination and your ability to protect yourself from mosquito bites. CDC recommends that pregnant women and couples planning a pregnancy within the next 3 months consult with a health care provider in making this decision.

1These countries have a potential risk of Zika, but we do not have accurate information on the current level of risk. As a result, detection and reporting of new outbreaks may be delayed.

2Because Aedes aegypti mosquitoes (the mosquitoes that most commonly spreads Zika) are present in these countries, Zika has the potential to be present, along with other mosquito-borne infections. Detection and reporting of cases and outbreaks may be delayed.

3No Aedes aegypti mosquitoes (the mosquitoes that most commonly spreads Zika) have been reported in these countries. However, other Aedes species mosquitoes have been known to spread Zika, and these may be present.
