(CBS) - 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, health officials say.
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.
The researchers said this case study emphasizes the need for all couples -- including women who have sex with women -- to take measures to prevent HIV transmission. These steps include avoiding all contact between HIV-infected blood or blood-contaminated bodily fluids and broken skin, wounds or mucus membranes.
The report is published in the March 13 issue of the U.S. Centers for Disease Control and Prevention's Morbidity and Mortality Weekly Report.
