Understanding Bloodborne Pathogens

Bloodborne pathogens are microorganisms, such as viruses, that are present in human blood and can cause disease. These pathogens can be transmitted from one person to another under the right conditions, and often show no visible signs or symptoms in those who carry them. Common examples include hepatitis B, hepatitis C, and HIV (human immunodeficiency virus).

Key Points About Bloodborne Pathogens

It is important to remember that not everyone’s bodily fluids contain bloodborne pathogens. However, for safety, always assume that these pathogens may be present in any blood you encounter.

Bodily Fluids Containing Pathogens

Bloodborne pathogens can be present in various bodily fluids, especially those visibly contaminated with blood. Other fluids that may pose a risk include:

• Cerebrospinal fluid - Surrounds the brain
• Synovial fluid - Lubricates joints
• Pleural fluid - Found in the lungs
• Amniotic fluid - Surrounds a baby in the uterus
• Semen, vaginal secretions, and urine

Modes of Transmission

Diseases caused by bloodborne pathogens can be transmitted through:

• Sexual contact
• Contact with contaminated sharp objects (e.g., needle sticks, broken glass)
• Exposure to infected body fluids through open cuts or mucous membranes (eyes, mouth, ears, or nose)
• Contact with contaminated objects touching inflamed skin, acne, or abrasions

Protective Measures

Intact skin serves as an effective barrier against disease, as bloodborne pathogens cannot penetrate unbroken skin. However, be aware that even small cuts or abrasions can provide a pathway for infection.

Always handle bodily fluids with caution, assuming that they could contain infectious materials such as hepatitis B, C, and HIV. Implementing rigorous safety protocols will help minimise the risk of transmission.
