Disinfection

According to the German Pharmacopoeia (DAB), disinfection means "putting dead or living material in a state that it can no longer infect". Various disinfectants are used for disinfection. Depending on where they are used, a distinction is made between hand disinfectants, surface disinfectants and instrument disinfectants. Technically, a distinction is made between disinfection and sterilisation. Disinfection is defined as a reduction of germs by a factor of at least 105, i.e. of the original 100,000 reproductive germs (so-called colony-forming units - CFU), no more than one survives. When disinfecting hands, a distinction is made between so-called "hygienic" and "surgical" hand disinfection. https://de.wikipedia.org/wiki/Desinfektionsmittel
