Submitted on: September 8, 1993 By Cheryl Clark Copley News Service SAN DIEGO The question arose again Friday (Sept. 3), especially in light of recent news reports. "What is the risk that AIDS can be transmitted through lesbian sex?" No one really knows, answered Judith Cohen, the opening speaker at the University of California at San Diego's Western Regional Conference on HIV, AIDS and Women. "Given the way the Centers for Disease Control and Prevention classifies people with AIDS, they will not at this time, nor will they ever ... be able to answer this question. If she acquires it from another woman, she doesn't fit (the CDC categories)," said Cohen, the director of a women's AIDS research project at UC San Francisco. "Does it happen? We think it does. How often? Try and find out," she said. Several conference workshops yesterday focused on the issue, following a report last week quoting a Texas physician who said he was treating two lesbians infected with the AIDS virus through lesbian sex, supposedly the first documented cases. Not so, said CDC epidemiologist Susan Chu, interviewed by telephone from Atlanta. Chu said the physician was misunderstood. "There was only one case that might have qualified, and she had sex with both men and women." While there have been five reports in medical literature of women suspected of becoming infected through sex with women, none have been proven, Chu said. And among 164 cases of AIDS that the CDC has documented in women who reported sexual contact only with other women, 93 percent were also intravenous drug users and 7 percent had received blood transfusions, both more likely routes for their infection, Chu said. The cases were recorded by the CDC through June 1991. The problem, said Chu, is that woman-to-woman sexual transmission "is hard to prove without fancy DNA testing ... and that's expensive." "Women with AIDS who report sexual contact only with other women represent a very small portion of the total number of women with AIDS in the United States," said her report, published last year in the journal AIDS. Chu said there is increasing evidence that some women who consider themselves lesbians have sex with men and that those men tend to be bisexuals. "Those lesbians are going to be at risk," Chu said. Women members of AIDS Coalition to Unleash Power (ACTUP) and several San Diego women's health groups are concerned that public health officials overlook the lesbian's risk of getting AIDS because the subject is distasteful. "We're 12 years into this disease, why aren't they asking the proper questions?" said Alicia Zee, a drug and alcohol counselor at Stepping Stone, a gay and lesbian recovery program in Hillcrest. "Maybe it is low risk right now, but why don't we start looking at this before it becomes high risk?" Gay and lesbian organizations have teamed up with AIDS Foundation San Diego to hold a conference on the issue Sept. 18 at the Gay and Lesbian Community Center in Hillcrest. AIDS testing forms don't even have a category for a woman who has sex with another woman," said Kristie Mills, an HIV drug and alcohol counselor for Episcopal Community Services. Steve Hart of the county HIV testing program said the form is being revised to reflect more types of behavior. Chu said she is concerned that "there is so much energy and resources in the lesbian community (directed) to preventing transmission of AIDS when the serious health problems are drug and alcohol abuse, cigarette smoking and getting routine gynecological care." "Those are probably bigger, more pervasive problems," acknowledged Pam Rahn of Stepping Stone. "But," said Rahn, a bisexual, "that doesn't mean we need not worry about AIDS."
