CDC: Woman to Woman HIV Transmission Rare, but Possible

HealthDay News -- A case report of a woman who was infected with HIV during sex with another woman shows that such transmission of the virus is possible, CDC officials said in Morbidity and Mortality Weekly Report.

The case occurred in Texas in 2012 and involved two women who were a monogamous couple for six months. One of them had HIV, and the other did not. The couple routinely did not take any protective measures during sex, and had engaged in sexual activity that resulted in the exchange of blood through abrasions.

The partner who had been HIV-free became infected. Health officials could find no other HIV risk exposures for the newly infected woman, and concluded that it was likely she was infected by her partner.

Although the risk of HIV transmission between female sex partners is low, it can occur when bodily fluids such as menstrual blood and vaginal fluids come into contact with a cut, abrasion or a mucus membrane (the tissue that lines body cavities such as the mouth and vagina).

This case study emphasizes the need for all couples -- including women who have sex with women -- to take measures to prevent HIV transmission, the researchers noted. These steps include avoiding all contact between HIV-infected blood or blood-contaminated bodily fluids and broken skin, wounds or mucus membranes.
