What do bloodborne pathogens refer to?

This definition encompasses a range of infectious agents that can lead to serious health issues, such as hepatitis B, hepatitis C, and HIV.

The selection of the first option signifies an understanding that these pathogens are primarily associated with blood and certain body fluids, highlighting their potential danger in healthcare and other environments where exposure may occur.
