Sterilization is the process of decontaminating surfaces and objects, while sterilization makes sure that all the harmful microorganisms are killed /deactivated, disinfection is basically for surface cleaning only, and done by chemicals.

Sterilization ensures that there is no microbe transmission from one to another and the microbes don’t grow. Medical sterilization is of utmost importance, and all the doctors, as well as pathologists make sure that the needles, bandages, dressings etc. are appropriately sterilized so that the patients are not infected with microbes from someone else.
