CDC recommends that pregnant women not travel to areas with risk of Zika. If a pregnant woman is considering travel to one of these areas, she should talk to her healthcare provider. If she travels to an area with risk of Zika, she should be counseled to strictly follow steps to prevent mosquito bites and sexual transmission of Zika during the trip. All travelers should continue to take steps to prevent mosquito bites for at least 3 weeks after they return home to prevent spreading Zika to uninfected local mosquitoes. See CDC’s Travelers’ Health Zika webpage for more information on international travel precautions. See Areas with Zika for recommendations for the United States.
Preventing Sexual Transmission
Pregnant women whose sexual partners have traveled to or lived in an area with risk of Zika should use condoms every time they have sex (vaginal, anal, and oral sex, and sharing of sex toys) or not have sex during the entire pregnancy. For more information, see Zika and Sexual Transmission.
If Zika testing for a pregnant woman is indicated, healthcare providers should provide pretest counseling. In particular, healthcare providers should
- Provide the patient with information on the complexity of Zika testing, including the following points:
- More than one Zika test may be required before a final result is determined.
- Understanding test results can be challenging.
- Previous exposure to Zika virus could affect test results during pregnancy.
- Discuss each type of Zika test with the patient.
- Discuss with patients what test results could mean for their pregnancy.

Note on the US-Mexico Border
The United States-Mexico border region is unique in that many people move fluidly and regularly (for example, daily, weekly) between the two countries to live, work, attend school, socialize, and seek medical care. Those who live in the border area may not regard movement between border cities or states as “travel.” This context should be considered when asking women in this area about travel history and potential exposure to Zika.
