What is a key principle of Universal Precautions?

The key principle of Universal Precautions is to treat all human blood and certain bodily fluids as potentially infectious. This approach is fundamental in preventing the transmission of infections and is rooted in the understanding that one cannot always identify whether a person is carrying an infectious disease simply by appearance or behavior. By adopting the mindset that any blood or bodily fluid could be a source of infection, healthcare and flight attendants can ensure they take the necessary precautions to protect themselves and others.

This principle is particularly relevant in high-risk environments, where exposure to bodily fluids might occur, such as during medical emergencies on flights. It leads to the use of protective equipment, such as gloves and masks, when dealing with any situation involving potential exposure, thereby promoting overall health and safety. The emphasis on treating all bodily fluids as potentially infectious establishes a universal standard that can be applied consistently, minimizing the risk of transmission of bloodborne pathogens.
