Many women who are pregnant and traveling are concerned about the potential to contract the Zika virus. For many of my patients who express concern, I always tell them it is important to know what exactly the Zika virus is, the risks and what to do if either them or their partner has been exposed. Here are some of their most commons questions answered.

Zika: What Is It?

The Zika virus is a primarily viral disease that causes poor fetal outcomes in infected pregnant women. While mosquitoes are the primary carrier, it can also be sexually transmitted through semen or cross the placental barrier from a pregnant woman’s blood to her baby’s. Zika is associated with several days to a week of fever, rash, joint pain and red eyes.

This is not a new virus, but recently confirmed cases in Brazil, Mexico and countries in central and South America have caused the virus to gain national attention.

What Are the Risks?

Pregnant women infected with Zika are at risk of pregnancy loss, microcephaly (small fetal head), poor brain development, eye defects and impaired growth in their baby. In a recent study from Brazilpublished in The New England Journal of Medicine, 29 percent of women with known Zika had abnormal ultrasounds. For this reason, travel to known Zika-infected areas is not recommended during pregnancy.

If travel is absolutely necessary, talk to your healthcare provider and take measures to avoid mosquito exposure.

What If I Have Been Exposed?

Pregnant women with possible Zika exposure should have a blood test for the virus. If the test comes back positive, it is recommended the patient undergo serial ultrasounds to monitor fetal development throughout the remainder of her pregnancy. If the blood test is negative, a single fetal ultrasound to screen for Zika- consistent abnormalities is still recommended. If this ultrasound is abnormal, then another blood test will be sent for Zika, after which, if negative, will require no further testing.

It is not known how long Zika lives in sperm; therefore, men with possible Zika exposure should refrain from sex or use condoms throughout their partner’s pregnancy. In addition, couples considering conception should take certain precautions if they have been in a Zika area. Men with known Zika (or symptoms) should use condoms or abstain for six months before trying to conceive and women with known Zika (or symptoms) should wait at least eight weeks.

Additionally, men who have traveled to a known Zika area and have not developed symptoms should still wait at least eight weeks before trying to conceive with their partner.
