What are blood borne pathogens?

Blood borne pathogens refer to infectious microorganisms present in human blood that can cause diseases and infections in humans. This primarily includes viruses, bacteria, and other pathogens that can be transmitted through direct contact with infected blood or bodily fluids. The significance of recognizing blood borne pathogens lies in their potential to cause serious health issues, such as hepatitis B, hepatitis C, and HIV/AIDS.

Understanding the nature of these pathogens is crucial for healthcare providers and individuals in various settings to implement appropriate safety protocols, such as the use of personal protective equipment (PPE) and adherence to proper sanitation practices to minimize the risk of transmission.

The other options describe characteristics of substances or pathogens that do not align with the definition or concerns surrounding blood borne pathogens. For example, viruses solely affecting the respiratory system, or beneficial bacteria, do not meet the criteria of being found in blood or being related to the specific risks associated with blood borne infections.
