Bloodborne pathogens are specifically defined as infectious microorganisms that are present in human blood. These pathogens can cause diseases in humans and are transmitted primarily through direct contact with blood or other potentially infectious bodily fluids. This includes, but is not limited to, viruses such as hepatitis B, hepatitis C, and HIV.

Understanding the nature of bloodborne pathogens is critical in healthcare settings and other environments where exposure to blood could occur, as it guides the implementation of safety protocols and practices to prevent transmission. Effective practices include the use of personal protective equipment, proper disposal of sharp instruments, and adherence to universal precautions.

The other options refer to different types of pathogens that do not share the same transmission pathway. Airborne pathogens are transmitted through the air, waterborne pathogens through contaminated water, and zoonotic pathogens from animal sources, all of which are distinct from the transmission route of bloodborne pathogens.
