What is sterilization?

What is sterilization?

• A. All microorganisms are destroyed.
• B. Most but not all pathogens are destroyed.
• C. Some microorganisms may survive.
• D. Only viruses are destroyed.

Answer: (A)

Sterilization means destroying all forms of microbial life on or in an object, including bacteria, viruses, and especially spores. In healthcare, items that are sterilized are free from viable organisms and can be used for sterile procedures. This is different from disinfection, which reduces pathogens but may not kill every organism, and from sanitization, which lowers overall microbial counts to safe levels. Therefore, the description that all microorganisms are destroyed best captures what sterilization means. The other statements imply that some microbes survive, that only viruses are affected, or that not all microbes are eliminated, which do not fit the concept of sterilization.
