Federal health officials confirmed the first case of HIV transmission between a lesbian couple in a serodiscordant relationship, one in which one partner is HIV positive and one is negative. Transmission between women is extrememly rare. As a precaution, officials are advising lesbian couples in serodiscordant relationships to take any necessary precautions to protect themselves.
Genetic tests showed that the virus in both women was more than 98 percent identical, all but proving that one had infected the other, according to the Morbidity and Mortality Weekly Report issued by the Centers for Disease Control and Prevention.
In an editorial, C.D.C. officials advised that all infected people having sex with uninfected people stay on daily antiretroviral drugs, which can reduce virus levels in blood and bodily fluids so much that transmission is highly unlikely.
