What does the term 'disinfect' refer to in the context of infection control?

In the context of infection control, the term 'disinfect' specifically refers to the use of a chemical agent to destroy a significant number of pathogens on surfaces, thereby reducing the likelihood of transmission of infections. Disinfectants are designed to target and eliminate most harmful microorganisms, although they may not eradicate all types of pathogens, especially spores. This is a critical aspect of infection control in environments like dental practices, where ensuring the safety of both patients and staff is essential.

The other concepts touch on different processes. Complete elimination of all pathogens is more accurately described as sterilization, which goes beyond disinfection. Cleaning surfaces refers to the removal of dirt and organic matter, which is a preliminary step that often needs to occur before disinfection can be effective. The introduction of new pathogens, on the other hand, runs contrary to the objective of infection control, which is to prevent the spread of infections. Understanding these distinctions emphasizes the importance of using the correct terms and methods in infection control practices.
