-
Hepatitis B Virus (HBV): A virus that causes liver infection, which can lead to chronic liver disease, liver cancer, and death.
-
Hepatitis C Virus (HCV): Another virus causing liver disease, which can also lead to chronic liver conditions.
Other pathogens that can be transmitted through blood include:
-
Syphilis
-
Malaria
-
Brucellosis
-
Leptospirosis
-
Arboviral infections (such as West Nile virus)
Modes of Transmission
Bloodborne pathogens can be transmitted in several ways:
-
Needle Stick Injuries: Accidental punctures by needles or other sharp objects contaminated with infected blood. Contaminated needles pose significant health risks as they can transmit bloodborne pathogens.
-
Contact with Broken Skin: Exposure to infected blood through cuts, abrasions, or any skin breaks.
-
Mucous Membrane Exposure: Bloodborne pathogens can enter the body through the eyes, nose, or mouth.
-
Direct Blood Contact: Handling or being splashed with infected blood or OPIM.
-
Perinatal Exposure: From an infected mother to her baby during childbirth.
The Importance of Bloodborne Pathogen Training
