The majority of AIDS cases occur in homosexual men, the second in a group of intravenous drug users (intravenous drug abusers), which accounts for 17% of AIDS cases, and these two groups account for almost the reported 90% of AIDS cases. About half of AIDS cases are reported to come from New York City, accounting for more than 85% of intravenous drug abuse cases in the New York metropolitan area.
