Step-by-step explanation:
The CDC guidelines that require the employer and employee to assume that all human blood and body fluids are potentially infectious are currently called Universal Precautions. Universal Precautions is an approach to infection control that treats all blood and body fluids as if they are infectious, regardless of the perceived infectiousness of the source. This approach helps to prevent the transmission of bloodborne pathogens, such as HIV and hepatitis B, in healthcare settings. By following Universal Precautions, healthcare workers can minimize the risk of exposure to potentially infectious materials.
