Gay-related immune deficiency (GRID) was the name first proposed in 1982 to describe an "unexpected cluster of cases" of what is now known as AIDS, after public health scientists noticed clusters of Kaposi's sarcoma and pneumocystis pneumonia among gay males in San Francisco, Los Angeles and New York City. During this time, the phrase "gay cancer" was also used. During the early history of AIDS, when it was considered a disease of homosexual men, at least one physician suggested that male homosexuals reconsider the practice of engaging in anonymous sex.
