Human immunodeficiency virus (HIV)-related Kaposi’s sarcoma (KS) is 10 times commoner in homosexual men than in other transmission groups and is four times more frequent in HIV-positive patients who acquired their infection from blood transfusions than in haemophiliacs. These observations lead Beral et al (1990) to propose that a second infectious agent could account for the prevalence of KS in immunodeficient patients and a cohort study of gay men with AIDS suggested that frequent faeco-oral contact was a possible transmission mode for the putative infectious agent (Beral et al, 1992).
