Medical student exposure to blood and infectious body fluids.

Few data assess the exposure of students to blood or other potentially infectious body fluids during medical school. Fourth-year medical students completed a written survey immediately before graduation describing exposures during their last 2 years. Nearly one half of all graduating students recalled at least one exposure, with only 40% of these exposures reported to supervising house staff or faculty. Clerkships with the highest exposure rates were emergency medicine, surgery, and obstetrics-gynecology.
