Result? --the "annual incidence of hepatitis A in...homosexual men was 22 percent, whereas no heterosexual men acquired hepatitis A." In 1992,26 it was noted that the proportion of London gays engaging in oral/anal sex had not declined since 1984.

While the body has defenses against fecal germs, exposure to the fecal discharge of dozens of strangers each year is extremely unhealthy. Ingestion of human waste is the major route of contracting hepatitis A and the enteric parasites collectively known as the Gay Bowel Syndrome. Consumption of feces has also been implicated in the transmission of typhoid fever,9 herpes, and cancer.27 About 10% of gays have eaten or played with [e.g., enemas, wallowing in feces]. The San Francisco Department of Public Health saw 75,000 patients per year, of whom 70 to 80 per cent are homosexual men....An average of 10 per cent of all patients and asymptomatic contacts reported...because of positive fecal samples or cultures for amoeba, giardia, and shigella infections were employed as food handlers in public establishments; almost 5 per cent of those with hepatitis A were similarly employed."10 In 1976, a rare airborne scarlet fever broke out among gays and just missed sweeping through San Francisco.10 The U.S. Centers for Disease Control reported that 29% of the hepatitis A cases in Denver, 66% in New York, 50% in San Francisco, 56% in Toronto, 42% in Montreal and 26% in Melbourne in the first six months of 1991 were among gays.11 A 1982 study "suggested that some transmission from the homosexual group to the general population may have occurred."12
