What level of disinfection is required for semi-critical items?

High-level disinfection is required for semi-critical items because these tools contact mucous membranes or nonintact skin and therefore pose a real risk of transmitting infection if not properly disinfected. The goal is to inactivate all microorganisms that could cause disease, including bacteria, viruses, and fungi, and to address most spores. This level sits above low-level disinfection in rigor because it reliably reduces the risk of transmission from items that enter or touch mucous membranes. Sterilization could be used when feasible and is the ultimate level of microbial kill, but many semi-critical items are heat- or damage-sensitive, so high-level disinfection provides a practical and effective standard.
