Occupational Exposure to Blood

Occupational exposures can occur through needlesticks or cuts from other sharp instruments contaminated with an infected patient's blood (including blood contaminated saliva) or through contact of the eye, nose, mouth, or skin with a patient's blood. Health care personnel are at risk for occupational exposure to bloodborne pathogens — pathogenic microorganisms that are present in human blood and can cause disease in humans. These pathogens include, but are not limited to, hepatitis B virus (HBV) and human immunodeficiency virus (HIV).  Following a specific exposure, the risk of infection varies depending on factors such as:

  • The pathogen involved.
  • The type and severity of exposure
  • The amount of blood involved in the exposure
  • The amount of pathogen in the patient's blood at the time of exposure.

Although most exposures do not result in infection, the exposed person should be evaluated immediately by a qualified health care professional1 in case treatment is needed.

1. A qualified health care professional is any health care provider who can provide counseling and perform all medical evaluations and procedures in accordance with the most current recommendations of the U.S. Public Health Service, including providing postexposure chemotherapeutic prophylaxis when indicated.
