On Thursday the CDC reported a rare case of suspected HIV transmission from one woman to another.
The government organization says, the 46-year-old woman “likely acquired” human immunodeficiency virus while in a monogamous relationship with an HIV-positive female partner in Texas.
The woman had been in heterosexual relationships in the past, but not in the 10 years before her HIV infection.
Her HIV-positive partner, a 43-year-old woman who first tested positive in 2008, was her only sexual partner in the six months leading up to the test that came back positive for HIV.
She did not participate in any other risk factors for contracting the virus, such as injecting drugs, organ transplant, tattoos or acupuncture.
The strain of HIV with which she was infected was a 98 percent genetic match to her partner's.
The partner who was infected since 2008 had been prescribed anti-HIV drugs in 2009 but stopped taking them in November 2010.
The CDC cautions that while such cases of HIV transmission are rare, “female-to-female transmission is possible because HIV can be found in vaginal fluid and menstrual blood.”
Doctors say people with HIV should be under the care of a doctor and take their prescribed medications to keep their viral load down and reduce the risk of infecting others.
The CDC is aware of two other previous suspected cases of a woman-to-woman transmission.
