Sanitation, Disinfection, Sterilization are three categories of infection control.

• A. Three categories of infection control
• B. A single practice
• C. A type of PPE
• D. A cleaning product

Answer: (A)

Infection control is handled through three levels of microbial control, each with a specific goal and method. Sanitation reduces dirt and microbes to safe levels through cleaning. Disinfection goes further by eliminating most pathogens on surfaces that can be touched during service. Sterilization is the highest level, destroying all microorganisms, including spores, on instruments that enter sterile areas or contact tissues that should remain sterile. These represent three distinct categories of infection control, not a single practice, a type of PPE, or a cleaning product.
