Virucidal properties must be included in a chemical product used for which of the following infection control procedures?

Disinfection is the infection control procedure where virucidal properties in a chemical product are essential. Disinfectants are designed to eliminate most pathogenic microorganisms, including viruses, from surfaces and objects. This is particularly important in environments like esthetics practices, where the risk of viral transmission can occur through contact with contaminated surfaces or instruments.

Cleansing involves the removal of dirt, debris, and some microorganisms, but it does not necessarily involve killing them, which is why virucidal properties are not a requirement here. Sanitization aims to reduce the number of microorganisms to safe levels, but it does not guarantee the elimination of viruses. Sterilization is the process that eliminates all forms of microbial life, including viruses, but it typically involves different methods such as heat or chemical agents specifically designed for that purpose, rather than focusing solely on virucidal action.

Therefore, the inclusion of virucidal properties is a fundamental aspect of disinfection, ensuring that surfaces that may come into contact with clients are safe from viral pathogens.
