In what is believed to be the first reported case of transmission of the AIDS virus from a woman to a man through oral sex, two physicians reported this week that a 60-year-old man appears to have developed AIDS as a result of oral sex with a prostitute.

The man's only extramarital affair, he said, had occurred during the two years before he was hospitalized with symptoms of AIDS. He said he had frequented one prostitute with whom, he said, he engaged only in oral sex.

[Peter G. Spitzer] and [Neil J. Weiner] concluded that public health education about so-called safe sex practices should warn against exposure to body fluids not only in vaginal and rectal intercourse but also during other sexual practices, such as oral sex.
