Objective. —To determine the incidence of invasiveHaemophilus influenzaedisease in men with the acquired immunodeficiency syndrome (AIDS) or human immunodeficiency virus (HIV) infection and the proportion of disease due to serotype b. Design. —Population-based, active surveillance. Setting. —San Francisco (Calif) Department of Health. Participants. —All men 20 to 49 years of age with invasiveH influenzaedisease. Results. —The cumulative incidences of invasiveH influenzaedisease in men 20 to 49 years of age with AIDS and in HIV-infected men 20 to 49 years of age without AIDS were 79.2 and 14.6 per 100000, respectively, but only 33% of cases were due to serotype b. The corresponding rates for invasiveH influenzaeb disease were 11.3 and 7.6 per 100000. Conclusions. —Men with AIDS or HIV infection are at increased risk of invasiveH influenzaeinfections, includingH influenzaeb, but such infections are still infrequent in this population.
