Woman spread Zika through sex
A New York City woman infected her male partner with Zika virus through sex, the first time female-to-male transmission of the germ has been documented.
Zika is usually spread by mosquitoes, and health officials have known for some time that men can spread it through sex. The Centers for Disease Control and Prevention reported the case Friday and updated its advice for pregnant women.
The CDC now advises them to use protection if their sex partner has travelled to a Zika-infected region, whether the partner is a man or a woman.
The Zika virus causes only a mild illness, at worst, in most people. But infection during pregnancy can lead to severe brain-related birth defects for the fetus. The New York woman was not pregnant.
While this is the first documented case of a woman spreading Zika through sex, health experts say it is not surprising because most diseases that can be spread through sex can be spread by both men and women.
On the day the woman returned from a trip to a Zika-infected country, she had vaginal sex with her partner, without a condom, health officials were told.
She went to her doctor three days after her return, after developing common Zika symptoms such as fever, fatigue, rash and back pain. Tests showed Zika infection.
Seven days after they’d had sex, her male partner developed similar symptoms. Two days later, he went to the same doctor. The doctor tested him even though he hadn’t travelled from a Zika outbreak area and no cases of female-to-male transmission had been reported. He tested positive for Zika.
They both are in their 20s, but no other details about them were released, including where the woman travelled or when the infection started.
The CDC is now recommending that “barrier methods” be used by all pregnant women who have a sex partner who lives in or travels to a Zika outbreak area.
No woman-to-woman sexual transmission had been reported to date.
