Which term describes the process that destroys all microorganisms including spores and viruses?

• A. Sterilization
• B. Disinfection
• C. Sanitization
• D. Pasteurization

Answer: (A)

Sterilization is the process that destroys all microorganisms, including spores and viruses, leaving no viable life on the item. This is why it’s the highest level of microbial control used in healthcare. Disinfection removes or inactivates many pathogens but may not kill spores and some resistant viruses. Sanitization lowers the overall microbial load to safe levels rather than eliminating all life. Pasteurization uses heat to reduce pathogens but does not eliminate all microorganisms or spores. In practice, sterilization methods—such as autoclaving, dry heat, chemical sterilants, or irradiation—are chosen for objects that must remain completely free of viable microbes, like surgical instruments and implants.
