How can you prevent infection with Zika virus?
Currently, there is no vaccine for Zika virus.
However, you can reduce your risk of getting Zika virus by:
- protecting yourself from mosquito bites at all times when travelling to countries or areas in the U.S. with reported mosquito-spread Zika virus
- using condoms correctly and consistently if you or your sexual partner have travelled to those areas
- avoiding travel to those areas if you are pregnant or planning a pregnancy. If travel can't be avoided or postponed, strict mosquito bite prevention measures should be followed. This is especially important because of the risk to a developing fetus.
Consult a health care provider or visit a travel health clinic preferably 6 weeks before you travel.
What should you do if you've travelled to a Zika-affected country?
If you want to become pregnant after returning home, we strongly recommend you wait at least 2 months before trying to conceive. This time is what your body needs to clear any possible Zika virus infection.
Zika virus can survive a long time in the semen of infected males. We strongly recommend that you wear condoms correctly and consistently or avoid having sex:
- with a pregnant partner for the duration of the pregnancy
- for 6 months after travel before you and your partner try to conceive
- for 6 months after travel with any sexual partner
Men who have returned from Zika-affected countries should postpone semen donations for 6 months.
Men and women who have travelled to Zika-affected countries or areas should wait a minimum of 21 days before donating:
