Dr. Jaffe presented an update on the risk of HIV infection to health care workers. He noted that information has come from three sources: 1) analysis of national AIDS surveillance data: 2) prospective studies of injuries and exposures of health care workers: and 3) anecdotal reports.

The national AIDS surveillance data indicate that 5% of reported AIDS cases occur in health care workers; health care workers represent 5.7% of the US workforce. By itself, this would suggest that employment as a health care worker is not associated with a disproportionately large risk of AIDS. The health care workers with AIDS have an age and sex distribution that is similar to that of all AIDS patients; the health care workers with AIDS are more likely to be white, however. The health care workers with AIDS are more likely to he homosexual/bisexual men (73%) than are all AIDS patients (62%); conversely, they are less likely to admit to intravenous drug use.
