What is the most effective level of infection control?

Sterilization
Sanitization
Disinfection
Antiseptic treatment

The correct answer is: Sterilization

Sterilization is the most effective level of infection control because it eliminates all microorganisms, including harmful bacteria, viruses, and fungi. Sanitization and disinfection only reduce the number of microorganisms, not completely eliminate them. Antiseptic treatment is used for controlling infections on living tissue and is not effective for environmental surfaces. Therefore, sterilization is the best option for ensuring the highest level of infection control.
