After Your Trip

Prevent Zika after travel

Protect your community from Zika! What to do after your trip

You can help protect people in your community from Zika after your trip. Even if you do not feel sick, you should take steps to prevent mosquito bites for 3 weeks after visiting an area with Zika so that you do not spread Zika to the mosquitoes in your area. If a mosquito bites an infected person while the virus is still in that person’s blood, it can spread the virus by biting another person. Remember that many people infected with Zika virus do not feel sick, so it is important for all travelers who have been to areas with Zika to prevent mosquito bites for 3 weeks.

Because Zika can also be spread by a man to his sex partners, men should use condoms during sex (vaginal, anal or oral) after travel to areas with Zika. Men with pregnant partners should either use condoms or not have sex during the pregnancy. All men should use condoms for at least 8 weeks if they don’t have symptoms, or at least 6 months if they have Zika symptoms or are diagnosed with Zika.

Couples who are trying to become pregnant should talk to their doctor about their travel plans and see CDC guidance for how long they should wait to get pregnant after travel to an area with Zika.

Pregnant travelers returning from an area with Zika can be tested for Zika. If you develop a fever with a rash, joint pain, or red eyes, talk to your doctor immediately and tell him or her about your travel. If you do not have symptoms, testing can be considered 2–12 weeks after you return from travel.

What if you feel sick after travel? Talk to your doctor if you develop a fever with a rash, joint pain, or red eyes. Tell him or her about your travel.

If you are not feeling well, you should see a doctor and mention that you have recently traveled.

You may wish to consult with an infectious disease doctor or travel medicine doctor. Most doctors who specialize in the diseases of travel are infectious diseases (ID) physicians. To find a list of private doctors who specialize in travel health, consult the directories located at: (American Society of Tropical Medicine and Hygiene - ASTMH) or (International Society of Travel Medicine - ISTM). CDC provides these directories as a courtesy to the public but does not endorse any health-care provider.

If you have visited a malaria-risk area:

  • It is very important that you continue taking your antimalarial drug for 4 weeks (if you are taking doxycycline or mefloquine) or seven days (if you are taking atovaquone/proguanil) after leaving the risk area.
  • Malaria is always a serious disease and may be a deadly illness. If you become ill with a fever or flu-like illness either while traveling in a malaria-risk area or after you return home (for up to 1 year), you should seek immediate medical attention and should tell the physician your travel history.
