What term describes the process that reduces the number of microorganisms on surfaces to safe levels?

• A. Cleaning
• B. Sterilization
• C. Asepsis
• D. Disinfection

Answer: (D)

Disinfection lowers the number of microorganisms on nonliving surfaces to a level considered safe and reduces the risk of transmission. It targets pathogens but does not necessarily kill every microorganism or spores. Cleaning removes visible dirt and debris and may reduce some microbes but doesn’t guarantee a safe microbial level. Sterilization aims to destroy all microorganisms, including spores. Asepsis is a state of being free from disease-causing organisms, achieved through sterile techniques. Sanitization is a broader term often used to describe reducing microbial counts to safe levels in some settings. In the context of surfaces and routine infection control, disinfection is the process that achieves the safe reduction described.
