Which practices aim to reduce the number and spread of micro-organisms?

Medical asepsis is focused on reducing the number and spread of micro-organisms to prevent infections in healthcare settings. This practice involves techniques such as hand hygiene, the use of barriers like gloves and masks, and appropriate cleaning and disinfection of surfaces and equipment. By lowering the microbial count, medical asepsis helps create a safer environment for both patients and healthcare providers.

While surgical asepsis also aims to eliminate micro-organisms, it takes place in specific situations, such as during surgical procedures, where a sterile field is required to prevent infection. Contamination techniques refer to actions that could introduce harmful pathogens, which is contrary to the goal of reducing organisms. Exposure control generally relates to preventing contact with hazardous substances and does not specifically target microorganisms. Therefore, medical asepsis is the most appropriate choice when discussing practices intended to reduce the overall presence and transmission of micro-organisms.
