Which body fluids are potentially infectious during an occupational exposure?

Any and all: Depending on the disease carried by the individual in question, any and all body fluids can be and should be considered potentially infectious. People like health care workers who are routinely exposed to bodily fluids must undergo special training in how to handle them safely and take regular vaccinations against things like hepatitis b. Treat all bodily fluids as potentially infectious.

Depends...: ...on the infectious agent, some are only in blood and others can be found in other fluids. Blood, peritoneal fluid, pleural fluid, pericardial fluid, semen, and vaginal secretions should always be considered infectious. ANY fluid that is visibly contaminated with blood should be considered infectious. Saliva, droplets from sneezes, urine, feces and vomit can be infectious depending on the agent.
