After potential Zika exposure, how many months should a man abstain from sex or use condoms?

1. 3 months

2. 4 months

3. 6 months

4. 12 months

The correct answer is: 6 months

The recommendation for men to abstain from sexual activity or use condoms after potential Zika virus exposure is based on the concern that the virus can persist in the male reproductive system. Studies have shown that Zika can be detected in semen for several months after infection. The CDC advises that men who have been exposed to Zika should take precautions for at least six months following their potential exposure to prevent the transmission of the virus to sexual partners. The prolonged duration is necessary because even if a man does not exhibit symptoms, he can still harbor the virus in his genital fluids, thus posing a risk for sexual transmission. This six-month guideline is particularly crucial regarding potential risks to pregnant partners, as Zika infection during pregnancy can cause serious birth defects. Consequently, it is essential to adhere to these precautions to ensure safe sexual practices after exposure to Zika virus.
