Overarching Principle
The objective in sanitation, sterilization and disinfection is to control microorganisms, or pathogens, in the environment, thus protecting patients and staff from contamination and disease, and thereby promoting optimal healing and wellness.
The Ever Present Danger
Improper application of the methods of sanitation, sterilization and disinfection can lead to microbial resistance and increase the risk of nosocomial infection
