Women who are pregnant should not travel to areas with Zika. A map of countries with active Zika virus transmission can be found at http://www.cdc.gov/zika/geo/index.html. There is growing evidence that Zika virus can be spread from a pregnant woman to her unborn baby and cause a serious birth defect of the brain called microcephaly, which means the baby’s brain and head are much smaller than they should be. If you must travel to an area with Zika, talk to your healthcare provider first and strictly follow steps to prevent mosquito bites during your trip. [source]
Cases of spread from an infected man to a woman through having sex have been reported, and a man who has had Zika disease and recovered may still be able to spread Zika through having unprotected sex for some time afterward.
- Men who travel to areas with Zika and develop symptoms of possible Zika infection in the 3 weeks after their return should see their healthcare provider and take care to use condoms correctly when having sex for at least 6 months.
- Men who travel to areas with Zika but do not develop symptoms should avoid sex with their pregnant partner for the duration of her pregnancy, unless condoms are used correctly.
- Men who travel to areas with Zika but do not develop symptoms of possible Zika infection and do not have a pregnant partner should take care to use condoms correctly for at least 6 months after exposure.
