New York City’s Health Department on Friday reported the first female-to-male transmission of the Zika virus, which is most typically spread by the bite of an infected mosquito.
The U.S. Centre for Disease Control and Prevention said the report was the first documented case of sexual transmission of Zika from a woman to her male sex partner.
“All previously reported cases of sexually transmitted Zika virus infection have been spread from men to their sex partners,” the Atlanta-based CDC said in a statement.
In the New York case, transmission of the virus occurred on the day that a woman in her 20s returned to the city from an area with active Zika transmission.
The statement said she had a single event of unprotected sex with a male partner.
“The man had not travelled outside of the U.S. in the prior year.
“The woman developed fever, fatigue, a rash and body aches the next day, and sought treatment.”
Health department officials then confirmed her infection.
As soon as her male partner developed symptoms seven days later and sought treatment from the same caregiver, he, too, was diagnosed with Zika.
Health officials from New York reported the case in the CDC's weekly report on death and disease.
They said the timing and sequence of events support female-to-male Zika virus transmission through unprotected vaginal sex.
The CDC said it recommended that all pregnant women who have a sex partner who has travelled to or resides in an area with Zika use barrier methods such as a condom every time they have sex.
It also suggested that they should not have sex during the pregnancy.
However no cases of woman-to-woman Zika transmission have been reported, these recommendations now also apply to female sex partners of pregnant women.
According to CDC, it is updating recommendations for sexually active people in which the couple is not pregnant and for people who want to reduce personal risk of Zika infection through sex.
U.S. health officials have concluded that Zika infections in pregnant women can cause microcephaly, a birth defect marked by small head size that could lead to severe developmental problems in babies.
The World Health Organisation has said there is strong scientific consensus that Zika can also cause Guillain-Barre, a rare neurological syndrome that causes temporary paralysis in adults.
Report says the connection between Zika and microcephaly first came to light last fall in Brazil, which has now confirmed over 1,600 cases of microcephaly. (Reuters/NAN)
