Transmission of bloodborne pathogens in the work setting is a risk wherever workers may have contact with blood or body fluids as a result of their duties. The science is clear. There have been cases of hepatitis B, hepatitis C, and HIV resulting from occupational exposures. Risk of transmission has been greatly reduced by implementation of the requirements of the OSHA Bloodborne Pathogens Standard in 1992. The requirements of the law closely follow the recommendations of the CDC, based on current scientific understanding of these diseases. All the requirements of the OSHA Bloodborne Pathogens Standard must be followed in any workplace where workers may be exposed to bloodborne pathogens as part of their duties.
