The difference between disinfection and sterilization is briefly described
The application site and processing items are also different. Mainly used for sterilization of medical supplies and sterilization in the hospital into the body tissues and organs of sterile industrial products, disinfection treatment for daily life and workplace items, and also used to treat common places and items in the hospital.The methods of disinfection and sterilization can be divided into two categories: physical and chemical methods. The following terms are used to indicate the degree of inactivation of microorganisms by physical or chemical methods:
The selection of different treatment methods. Sterilization and disinfection, more demanding, more difficult to deal with. We must choose sterilization can kill most resistant microorganisms (bacteria Bacillus) physical or chemical sterilization and disinfection, only with physical methods, germicidal efficacy of chemical disinfectants or biological disinfectant. The processing method sterilization for disinfection is not only the overkill is not necessary, but also will produce side effects could not occur; and if the processing method for disinfection and sterilization, sterilization will lead to failure.
Processing requirements to meet the different levels of the two. Disinfection requires only kill or / and remove pathogenic microorganisms, the number reduced to no longer causes disease. Sterilization requires not only kill or / and remove pathogenic microorganisms, but also for all microorganisms all killed or / and removed, including non pathogenic microorganisms.In conclusion, disinfection only requires the place and articles to reach harmless levels, while sterilization requires no live bacteria
