According to a new study released on Friday, women were able to pass Zika virus infection to their male sexual partners.
Public health officials reported for the first time that a woman had transmitted the virus to her male partner while having sex.
All cases of Zika sexually transmitted infections previously reported came from men.
But according to the Centers for Disease Control and Prevention, a 20-year-old woman in New York City had sex with a male partner who did not wear condoms, the day she returned from Zika
Affected areas outside the United States.
The CDC reported that the next day, the woman developed symptoms of Zika: fever, fatigue, rash, joint and back pain, swelling, numbness and tingling in her hands and feet.
On the same day, the woman also began menstruation.
Two days later, she went to her primary care doctor, who took samples of blood and urine and sent them to the New York City Department of Health laboratory for testing.
The test was positive, indicating the presence of a virus in her blood and urine.
The couple developed fever, rash, joint pain and red eyes a week after having sex.
He went to the doctor who diagnosed the Zika virus.
The doctor suspected that the virus was sexually transmitted and informed the Health Department.
The 20-year-old man did not travel abroad a year before his illness, did not have other recent sexual partners, and was not bitten by mosquitoes a week before his illness.
Blood and urine samples were taken from the man, who had a positive virus test in his urine.
New York City health officials investigating the case said the woman's vaginal fluid or a virus present in menstrual blood could be transmitted to her male partner through an undiscovered scratch on the urethra mucosa or penis.
So far, scientists know that men with Zika virus can pass Zika virus on to women or male partners in unprotected sex, regardless of whether men have symptoms.
The virus stays longer in semen than in blood.
The latest findings suggest that the transmission of Zika is very similar to other sexually transmitted diseases.
"It's not surprising to see more women spreading Zika virus to sexual partners," said John Brooks, an STD specialist at CDC . ".
Since pregnant women infected with Zika virus can cause severe birth defects in infants, the latest research shows that pregnant women have female sexual partners who live in Zika virus or have been to Zika.
He said preventive measures are also needed in the affected areas.
CDC is updating its recommendation to address the sexually transmitted issue of the female Zika virus, although there are no female casesto-
Female communication has been recorded.
Pregnant women with female sexual partners should use a barrier method every time they make love to avoid repeated
Brooks says sex toys are used during pregnancy or sex is avoided.
Brooks says there is not enough evidence yet that sexual transmission "goes beyond a couple ".
"In areas where Zika continues to spread, it is difficult to determine how many infections are caused by mosquito bites and how many are caused by sexual transmission.
"The virus is spread mainly through the bite of infected mosquitoes.
In the case of New York, there are also two conditions for increasing the possibility of sexual transmission.
Brooks said the man was not circumcised, which always increases the risk of contracting sexually transmitted diseases such as HIV and herpes.
The woman was sick too.
There's a lot of Zika virus in her system.
Just when she had sex.
It is not clear how many viruses are in her vaginal fluid, but animal models show that there may be viruses in these secretions.
So far, CDC's guidance on preventing sexual transmission is based on the assumption that any transmission is transmitted from a man to his partner.
According to the latest information, officials recommend health
Care providers report to local or state health departments any patients with a disease compatible with Zika infection who do not have a history of traveling to a local area where the virus is transmitted, but sexual contact to a traveling partner.
The Zika virus has spread to nearly 50 countries, mainly in South America and the Caribbean.
