What body fluids are infectious for HIV, HBV, HCV?
Blood is the most infectious body fluid. In the health care setting, cerebrospinal, synovial, pleural, peritoneal, pericardial, and amniotic fluids are all considered potentially infectious, although the only documented cases of occupational HIV infection have been with blood, body fluids with visible blood, or HIV viral cultures. Unless there is visible blood with the exposure, saliva, nasal discharge, tears, sweat, vomit, urine, and feces are not infectious. Semen and vaginal secretions are infectious for HIV, HBV, and HCV in the setting of nonoccupational exposure.
