What is the purpose of treating all human blood and body fluids as potentially infectious?

Treating all human blood and body fluids as potentially infectious is a standard practice rooted in the principles of infection control and universal precautions. This approach, which emphasizes the importance of assuming that any exposure could involve pathogens capable of transmitting diseases, effectively minimizes the risk of disease transmission. This practice is particularly crucial in healthcare settings, where workers are frequently in contact with various bodily fluids and may be at risk of exposure to bloodborne pathogens such as HIV, hepatitis B, and hepatitis C.

By adopting this precautionary measure, healthcare practitioners can implement appropriate protective measures—such as using personal protective equipment (PPE), practicing proper hand hygiene, and employing safe disposal methods for sharps and other contaminated materials. This proactive mindset significantly lowers the chances of accidental exposure and subsequent transmission of infectious agents, thus safeguarding both healthcare workers and patients.
