Abstract
This study describes the professional risk of acquiring HIV infection while caring for AIDS patients at a teaching hospital in Brazil. Since 1985 we have tested health care professionals (HCP) for HIV-1 antibody after accidents with blood and body fluids from AIDS patients. The blood samples were tested twice using an ELISA FDA approved test and, if positive, we performed Western blot. Two hundred and forty seven health care professionals reported 338 accidents (50% were percutaneous and 22% were mucous membrane exposures to blood). A further 404 HCPs reported no occupational exposure but wanted to be tested. From 247 HCPs with at least one accident, we analyzed 115 with more than 6 months of follow up. None were HIV antibody positive. Nobody received zidovudine as a prophylaxis. Of the 404 HCPs with no accident, 6 (1.5%) were positive and had confirmed risk factors for HIV. Our results support other studies that report a low occupational risk (about 0.4%) of acquiring HIV infection.
