Zika Virus
About Zika
Zika PosterZika virus is spread to people mainly through mosquito bites. It can also be spread during sex and from mothers to unborn babies. Babies infected before birth are at risk for birth defects, including microcephaly. 

Not everyone gets symptoms from Zika infection. When present, they may include fever, rash, joint pain, and pink eye. Healthy people usually recover easily. 

Preventing exposure to Zika virus is very important because there is no vaccine and no treatment at this time. The CDC recommends pregnant women avoid travel to areas where Zika virus infections are occurring. For CDC's travel notices, click here.

If travel is unavoidable, pregnant woman and those trying to become pregnant should avoid mosquito bites, being aware mosquitos that carry Zika, bite at all times of the day.

Avoiding mosquito bites
  • Wear long-sleeved shirts and long pants.
  • Use U.S. Environmental Protection Agency (EPA)–registered insect repellents.
    • When used as directed, repellents containing DEET, picardin, and IR3535 are safe for pregnant women.
  • Use permethrin-treated clothing and gear.
  • Stay and sleep in screened-in or air-conditioned rooms.

Sexual Transmission of Zika
Men Can Pass Zika to Sex Partners
  1. Condoms can reduce the chance of getting Zika from sex if used correctly from start to finish, every time during vaginal, anal or oral sex.
  2. Not having sex can eliminate your risk of getting Zika from sex.
