Last Modified: Jun 2, 2020 Disinfection involves the destruction of microorganisms, but not usually spores, on inanimate surfaces or objects. Disinfection is not sterilization. Sterilization describes a process that destroys or eliminates all forms of microbial life, including spores. Disinfection methods can involve the use of physical (e.g., heat or ultraviolet light) or chemical (e.g., disinfectants) processes to reduce, inactivate, or destroy pathogenic microorganisms. Many factors can affect the effectiveness of the disinfection process. These include the microorganism being targeted, the organic and inorganic load present, the characteristics of the disinfectant (or disinfectant method) being used, as well as other factors such as temperature, pH, water hardness, relative humidity, and the physical nature of the object or surface being disinfected. For the use of physical disinfection methods, including heat, there are likely to be specific requirements and processes based on the situation and/or the disease agent involved.
