What are bloodborne pathogens?

Bloodborne pathogens are defined as microorganisms that are present in blood and can cause disease in humans. These pathogens can include a range of infectious agents, such as viruses (like HIV and hepatitis B and C), bacteria, and other microorganisms that may enter the bloodstream through breaks in the skin or mucous membranes.

Understanding this concept is vital in skin care and aesthetic practices, where exposure to blood or bodily fluids may occur. Proper protocols for infection control and safety measures, such as the use of personal protective equipment and sterilization of tools, are essential to prevent the transmission of these pathogens.

The other options describe microorganisms associated with different environments or sources, which do not specifically relate to blood or the potential health risks that arise from exposure to pathogens found in blood. Thus, option B accurately captures the essence of bloodborne pathogens and their implications in medical and aesthetic practices.
