Further along the spectrum are scores of nations where draconian sodomy laws are aggressively enforced, with penalties that include years in prison. Political and religious leaders in Botswana even tried to quash research into the subject, claiming that same sex activity did not exist in that country.

    Epidemiologists created the term men who have sex with men because a substantial portion of men who engage in that activity do not identify themselves as gay and often do not respond to HIV prevention interventions designed to reach members of the gay community. The term applies to populations within developed nations and especially in developing countries, where there often is little or no open gay community.
