In a health letter on September 25, 1995, the U.S. Centers for Disease Control and Prevention reported that avoiding sex that causes bleeding, or takes place while a woman is menstruating, cuts the risk of HIV infection. This CDC report was presented at the 11th meeting of the International Society for Sexually Transmitted Disease Research, which was held in New Orleans, Louisiana from August 27-30 in 1995. The CDC's letter focused on a case controlled analysis conducted by W.J. Kassler, in which 95 HIVcases of HIV transmission were closely studied. Kassler and his colleagues found that bleeding during sex accounted for 11% of the cases, and concluded that this type of transmission was a risk for both men, with a ratio of 8;1, and women, with a ratio of 4;1. Kassler also found that for women, having sex during menses, which accounted for 20% of the cases studied, was associated with a six-fold risk of transmission (6;1).
