Invasive Haemophilus influenzae infections in men with HIV infection.
OBJECTIVE
To determine the incidence of invasive Haemophilus influenzae disease in men with the acquired immunodeficiency syndrome (AIDS) or human immunodeficiency virus (HIV) infection and the proportion of disease due to serotype b.


METHODS
Population-based, active surveillance.


METHODS
San Francisco (Calif) Department of Health.


METHODS
All men 20 to 49 years of age with invasive H influenzae disease.


RESULTS
The cumulative incidences of invasive H influenzae disease 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 100,000, respectively, but only 33% of cases were due to serotype b. The corresponding rates for invasive H influenzae b disease were 11.3 and 7.6 per 100,000.


CONCLUSIONS
Men with AIDS or HIV infection are at increased risk of invasive H influenzae infections, including H influenzae b, but such infections are still infrequent in this population.
