Coronavirus disease 2019 (COVID-19) is a respiratory infection caused by SARS-CoV-2 (COVID-19 virus). The COVID-19 virus is transmitted mainly through close physical contact and respiratory droplets, while airborne transmission is possible during aerosol-generating medical procedures.
Transmission of the COVID-19 virus had not been conclusively linked to contaminated environmental surfaces in available studies. However, as per the WHO guidance document, it is informed by evidence of surface contamination in health-care settings and past experiences with surface contamination that was linked to subsequent infection transmission in other coronaviruses.
Therefore, our aim is to reduce any role that fomites might play in the transmission of COVID-19 in health-care and non-healthcare settings.
Transmission of the COVID-19 virus has been linked to close contact between individuals within closed settings, such as households, health facilities, assisted living, and residential institution environments.
In addition, community settings outside of health-care settings have been found vulnerable to COVID-19 transmission events including publicly accessible.
Cleaning helps to remove pathogens or significantly reduce their load on contaminated surfaces and is an essential first step in any disinfection process. Cleaning with water, soap (or a neutral detergent) and some form of mechanical action (brushing or scrubbing) removes and reduces dirt, debris and other organic matter such as blood, secretions and excretions, but does not kill microorganisms. Organic matter can impede direct contact of a disinfectant to a surface and inactivate the germicidal properties or mode of action of several disinfectants. In addition to the methodology used, the disinfectant concentration and contact time are also critical for effective surface disinfection. Therefore, a chemical disinfectant, such as chlorine or alcohol, should be applied after cleaning to kill any remaining microorganisms.
