– It can be sexually transmitted as well, when a man who has contracted the disease spreads it to his sexual partners. It is not known with certainty how long the virus can stay present in semen, but recent reports suggest a period of 10 weeks. Because that number is not 100% accurate and there is still a lot we don’t know, the CDC suggests that any men who have been to a Zika-affected area should always use condoms when engaging in sexual activity, or to be extra safe (especially if your partner is pregnant or hoping to become pregnant), abstain from sexual activity altogether until you know you are disease free.

– Perhaps the most frightening fact, “Zika virus can be passed from a pregnant woman to her fetus during pregnancy or at delivery,” according to the CDC.
