Trying to conceive? Here’s what you need to know about Zika


Many concerns have been raised about the potential threat the Zika virus poses to pregnant women and the children they are carrying.

While the risk to pregnant women seems clear, the risk to those who wish to become pregnant may less clear. What do couples seeking to become pregnant need to know?

Here’s what you need to know if you are trying to get pregnant and are concerned about the Zika virus:

How is Zika transmitted?

Zika is primarily transmitted through infected mosquitos. An infected mosquito bites a pregnant woman, who then passes the virus along to her fetus.

But transmission can also occur via unprotected sex. Zika virus can be passed through vaginal fluids and semen, and it remains in semen longer.

Infectious Zika virus has been detected in semen collected from men as many as three months after they began showing symptoms of infection. There have also been cases where asymptomatic men transferred the infection to their partners via sexual contact.

What risks does the Zika virus pose?

Pregnant women infected with the virus can pass it along to their unborn children. While Zika typically only causes mild symptoms in adults (fever, rash, joint or muscle pain, headache, conjunctivitis), it can have a devastating impact on the developing fetus, causing profound brain defects such as microcephaly.

Where is Zika a risk?

Two types of mosquitos carry the virus: The Aedes albopictus and Aedes aegypti. These mosquitos live in tropical, subtropical, and temperate climates. In the United States, their range dominates the southern states, including Kentucky.

Zika infections have not been found across the entire range, however. Zika has only been determined to be present and a risk in certain areas across the Caribbean, South America, Africa and Asia. In the United States, Zika infection has only been detected in Brownsville, Texas and Miami-Dade County, Florida.

What precautions should I take?

If you or your partner live in or travel to an area where Zika is a risk, you should take these precautions:

  • You should prevent mosquito bites by using an EPA-registered insect repellant that contains at least 20 percent DEET.
  • Women who live in or travel to an area where Zika risk has been identified should wait at least 8 weeks after their last possible exposure or symptoms before trying to conceive. A condom should be used during sex.
  • Because the virus survives longer in semen, men should wait at least six months after the last possible exposure or symptoms before trying to conceive. A condom should be used during sex.

Couples may want to consider banking sperm in advance of travel to high-risk areas if they don’t want to wait to try to conceive. Men should then follow the guidelines above and avoid unprotected sex for at least six months after last possible exposure or symptoms.

Couples using donor eggs or sperm should be also be aware that the FDA issued guidelines in early 2016 recommending that clinics screen potential donors for Zika exposure risk.

What if I do become pregnant, and I have been exposed to the Zika virus?

Pregnant women who have been exposed and show symptoms of Zika should be tested for the virus. The fetus will be monitored for possible risks throughout the pregnancy.

It’s also important to keep exposure and risk in perspective. Even if a woman who is pregnant becomes infected with Zika, that doesn’t necessarily mean her unborn child will be affected and will suffer profound birth defects.
