Practices that render and keep objects and areas free from microorganisms; synonym for sterile technique.
Transmission Based Precautions
CDC precautions used in patients known or suspected to be infected with pathogens that can be transmitted by air born, droplet, or contract routes; used in addition to standard precautions.
