What is the main function of low-level disinfection?

The main function of low-level disinfection is to destroy most vegetative bacteria and viruses present on surfaces. Low-level disinfection is particularly effective against common pathogens found in healthcare settings, such as those that cause healthcare-associated infections. This type of disinfection helps reduce the microbial load on surfaces, making them safer for patients and staff, particularly in environments like nursing homes where vulnerable populations reside.

Low-level disinfectants typically do not have the capability to kill more resistant organisms such as bacterial spores, nor do they provide a higher level of assurance required for certain medical applications, which is why complete sterilization or the elimination of all microorganisms is not associated with this method of disinfection. Understanding this distinction is crucial for appropriate infection control practices within healthcare settings.
