Abstract:
The corona virus disease 2019 (COVID-19), which started in Wuhan in December 2019, is a new infectious disease. The disease is highly contagious, and the correct selection of effective disinfectants is essential. This article analyzed the environmental resistance of coronavirus and its sensitivity to commonly used disinfectants by reviewing domestic and foreign literatures, and concluded that coronavirus has strong survivability in the environment, but it can be efficiently inactivated by most disinfectants. However, it should be noted that the commonly used concentration of chlorine-containing disinfectants (effective chlorine concentration of 500 mg/L) cannot quickly kill coronavirus, and a concentration of 1 000 mg/L or higher is required. Other biocidal agents, such as benzalkonium chloride and chlorhexidine digluconate, are less effective. This article aimed to provide references for selecting the appropriate disinfectants and disinfection methods to cut off the spread of the virus.
