The incidence rate of acquired immunodeficiency syndrome in selected populations.
Population figures were obtained, and incidence rates of acquired immunodeficiency syndrome (AIDS) for the 12 months from June 1, 1983, to May 31, 1984, were estimated for single (never-married) men aged 15 years or older, intravenous (IV) drug users, Haitians living in the United States, persons with hemophilia A and B, female sexual contacts of male IV drug users, and blood transfusion recipients. Single men in San Francisco and Manhattan, IV drug users in New York City and New Jersey, hemophilia A patients, and recent Haitian entrants had the highest rates of disease (82.0 to 268.9 per 100,000). Male IV drug users and male Haitians were two to four times as likely to experience development of AIDS as were females in each group. Persons with hemophilia A had six times the incidence rate of AIDS as did those with hemophilia B. Persons with severe hemophilia A had three times the rate of those with moderate and seven times the rate of those with mild clotting factor deficiency. Although blood transfusion recipients and female sexual contacts of male IV drug users had much lower average yearly rates than did persons in the four other groups (0.4 to 9.4 per 100,000), they still had a higher incidence rate of AIDS than did persons not belonging to any of these groups (0.1 per 100,000).
