Body Fluid Exposure and Mandatory Blood Testing Act

Blood, saliva, urine, feces, and other bodily fluids can carry infections. Exposure to these fluids poses a risk of infectious disease transmission. An exposure may include:

  • A needle stick or cut from sharp object contaminated with blood and/or bodily fluids
  • Blood or bodily fluids contact with broken skin (i.e., open cut, wound, dermatitis).
  • Blood or bodily fluids contact with mucous membranes (i.e., eyes, nose, mouth).

This page provides information for the general public to identify, prevent, and manage blood and body fluid exposures. There are also resources available for health care providers and individuals who are eligble for source testing under the Mandatory Blood Testing Act (MBTA).
