What level of disinfection kills most bacteria, TB, and fungi?

Intermediate Level Disinfection is the correct answer because it is specifically designed to kill a broad spectrum of pathogens, including most bacteria, tuberculosis (TB), and fungi. This level of disinfection usually involves the use of chemical agents that have proven effective against these microorganisms, making it suitable for surfaces and instruments that come into contact with intact skin or mucous membranes.

High Level Disinfection goes a step further and is typically used for items that are intended to come into contact with sterile tissue or the vascular system, effectively eradicates all microorganisms except large numbers of bacterial spores. This level exceeds what is necessary for general cleaning and disinfection of surfaces that don't require full sterilization.

Low Level Disinfection is primarily effective against some bacteria and viruses but does not provide the level of efficacy needed to kill TB or more resilient fungi.

Sterilization is the complete elimination of all microbial life, including spores, which is beyond the need for general disinfection procedures where intermediate level disinfection suffices.

Understanding these distinctions is crucial for applying appropriate infection control practices in healthcare settings, ensuring the safety of both patients and healthcare providers.
