Eight cases of hepatitis in adults were attributed epidemiologically to infections spread by means of inadequately sterilized needles and syringes used repeatedly in a physician's office practice. The patients' potential exposures and subsequent onsets of illness were compatible with a "common source" outbreak of hepatitis B. Historical and contemporary examples of hepatitis epidemics attributable to a variety of contaminated instruments emphasize the continuing importance of alertness to accepted standards of sterilization.
