The national Centers for Disease Control and Prevention reported that among men who have sex with other men, the proportion of those who had anal sex without condoms rose from 30 percent in 1994 to 39 percent in 1997. Those having unprotected sex with multiple partners grew from 24 to 33 percent, with males 25 and younger accounting for the largest increase in that group. The number of gay men who had sex with multiple partners also rose, and 68 percent of the men studied did not know whether their partners were infected with the AIDS virus. The study was based on 21,857 interviews conducted from 1994 to 1997. A San Francisco Department of Public Health study of the incidence of male rectal gonorrhea during the same period showed an increase from 21 to 38 per 100,000 adult men.
