The CDC advises that people wait six months to try for a pregnancy if either partner has been to a Zika-affected area -- even if he or she doesn't have symptoms. If a woman is pregnant and her male partner could possibly have been infected, they should use a condom or abstain from sex for the whole pregnancy. There's a report of one man who had Zika virus in his semen more than six months after he showed symptoms of infection. Since nearly half of the pregnancies in the U.S. are unplanned, CDC also advises using a condom or abstaining from sex for six months if there's a chance a man has been infected with Zika.
