Disinfectants work by destroying the cell wall of microbes or interfering with the metabolism. Germicides differ markedly, primarily in their antimicrobial spectrum and rapidity of action. What is the guidance for the disinfection of outdoor spaces such as open markets, roads? endobj
Disinfection Disinfection is a process that reduces the number of microorganisms to a level at which they do not present a risk to patients or clients. WebWhen used correctly, commercially available disposable disinfectant wipes, cloths, or towelettes are effective for cleaning and disinfecting environmental surfaces in dental settings. Disinfectiondescribes a process that eliminates many or all pathogenic microorganisms, except bacterial spores, on inanimate objects (Tables 1 and 2). Because sterilization of all patient-care items is not necessary, health-care policies must identify, primarily on the basis of the items intended use, whether cleaning, disinfection, or sterilization is indicated.

If used they should be single patient use and the soap only used by that patient. Factors that affect the efficacy of both disinfection and sterilization include prior cleaning of the object; organic and inorganic load present; type and level of microbial contamination; concentration of and exposure time to the germicide; physical nature of the object (e.g., crevices, hinges, and lumens); presence of biofilms; temperature and pH of the disinfection process; and in some cases, relative humidity of the sterilization process (e.g., ethylene oxide). <>

This practice could be physically and psychologically harmful and would not reduce an infected persons ability to spread the virus through droplets or contact.
