Prevention

Preventing Mosquito Bites

  • Wear long-sleeved shirts and long pants.
  • Use EPA registered insect repellent containing DEET, picaridin, IR3535, oil of lemon eucalyptus or para-menthane-diol, or 2 undecanone.
  • Empty standing water from containers such as flowerpots or buckets.
  • Protecting Children in Areas with Zika (CDC): EnglishSpanish
  • Visit the CDC’s Prevent Mosquito Bites page for more information.

Preventing Sexual Transmission

  • Zika can be passed through oral, vaginal and anal sex and the sharing of sex toys, even if the infected person does not have symptoms at the time. It can be passed from a person with Zika before their symptoms start, while they have symptoms, and after their symptoms end.
  • People with a partner who traveled to an area with Zika should use the following precautions:
    • If traveler is female: Use condoms or do not have sex for at least 8 weeks after travel to an area with Zika (if she doesn’t have symptoms) or for at least 8 weeks from the start of her symptoms (or Zika diagnosis).
    • If traveler is male: Use condoms or do not have sex for at least 6 months after travel to an area with Zika (if he doesn’t have symptoms) or for at least 6 months from the start of his symptoms (or Zika diagnosis).This extended period is because Zika stays in semen longer than in other body fluids.
  • Visit the CDC’s Protect Yourself During Sex page for more information.

Prevention During Pregnancy

  • Until we know more, CDC recommends special precautions for pregnant women. Pregnant women are advised not travel to areas with Zika. See the CDC’s Zika Travel Information page for up-to-date recommendations.
    • If you must travel, talk to your doctor or other healthcare provider first and take steps to plan for travel.
    • If your sex partner travels to an area with Zika, be sure to follow safe sex practices for the appropriate amount of time after their return.
  • Pregnant women who have traveled to areas with Zika should talk to their doctors about whether they should be tested for Zika infection.

Plan for Travel

  • All people who travel to areas where Zika virus is actively circulating should plan for travel. This includes checking for Zika travel notices for the area(s) you are traveling to, protecting yourself from mosquito bites while there, and practicing safe sex during your stay and after your return.
