Bloodborne pathogens are infectious microorganisms in human blood and other bodily fluids that can cause diseases in humans. Dental procedures are among the activities that pose a risk for occupational exposure to bloodborne pathogens. These pathogens can cause serious illness or death if not treated properly and quickly. The most common bloodborne pathogens include hepatitis B, hepatitis C, and HIV. In healthcare settings, janitorial staff are at an increased risk of exposure to these pathogens due to their regular contact with blood-contaminated fluids and surfaces. Proper training, protection, and the use of personal protective equipment (PPE) are essential to minimize the risk of infection. This comprehensive guide explores the nature of bloodborne pathogens, the risks faced by janitorial staff, and the measures needed to protect these essential workers.
Understanding Bloodborne Pathogens
Definition and Examples
Bloodborne pathogens are infectious agents present in human blood and other body fluids, as well as other potentially infectious materials (OPIM), that can cause disease in humans. Some common bloodborne pathogens include:
-
Hepatitis B Virus (HBV): Causes hepatitis B, a serious liver infection that can lead to chronic liver disease, liver failure, or liver cancer. HBV is transmitted through contact with infectious body fluids such as blood, semen, and vaginal secretions.
-
Hepatitis C Virus (HCV): Causes hepatitis C, a liver infection that can become chronic and lead to liver cirrhosis or liver cancer. HCV is primarily spread through contact with blood.
-
Human Immunodeficiency Virus (HIV): Attacks the body’s immune system, leading to acquired immunodeficiency syndrome (AIDS). HIV is transmitted through contact with blood, semen, vaginal fluids, rectal fluids, and breast milk.
Transmission Routes
Bloodborne pathogens can be transmitted through various routes, including:
-
Percutaneous Exposure: Needle sticks, cuts from other sharp instruments, and other injuries that break the skin.
-
Mucous Membrane Exposure: Splashing of blood or OPIM into the eyes, nose, or mouth.
-
Non-intact Skin Exposure: Contact with blood or OPIM on skin that is chapped, abraded, or afflicted with dermatitis.
