The process of using special substances to kill germs and bacteria on surfaces or in the air to make them safe and clean.
The hospital uses disinfection to ensure that all equipment is free from harmful germs.
Disinfection is formed from "dis-" (meaning apart) and "infectio" (from Latin "inficere", meaning to taint or stain). The word describes the process of removing or separating harmful microorganisms to prevent infection.
Think of 'dis-' meaning apart and 'infectio' meaning to taint — disinfection is the act of removing what taints or harms.
