Hepatitis, HIV, and the dermatologist: a risk review

The practice of dermatology has always carried with it the risk of patient-acquired infection. This review covers health risks associated with the care of HIV-infected patients and patients who are chronic carriers of hepatitis B or C virus, protection options to reduce exposure, and protocols should exposure occur. Hepatitis B continues to be a major risk to health care workers, killing approximately 200 per year. In contrast, as of 1990, only 327 total health care personnel had acquired HIV, with no deaths reported. Data are lacking regarding hepatitis C, but it appears to be an increasing concern. Needlesticks are the most common form of occupational transmission, with an infectivity rate of 30% for hepatitis B, 3% for hepatitis C, and 0.3% for HIV. Universal precautions are the cornerstones of safety. Hepatitis B vaccination, zidovudine prophylaxis, and hepatitis C therapy are discussed as postexposure recommendations are reviewed.
