The most effective level of infection control is

• A. Sanitation
• B. Sterilization
• C. Disinfectant
• D. Antiseptic

Answer: (B)

Sterilization provides the highest level of infection control because it destroys all forms of microbial life, including spores, on instruments and materials. That complete removal means nothing viable remains to cause infection, which is why it’s considered the most effective method. Sanitation lowers microbial counts on surfaces to a safe level but doesn’t achieve true sterility. Disinfection removes many pathogens but generally does not kill spores and isn’t universally effective on all instrument types. Antiseptic reduces microorganisms on living tissue, such as skin, but it cannot render tools sterile. In a skin-care setting, using sterilized instruments or disposable items is essential to prevent cross-contamination and infection.
