ABSTRACT
Objective To observe the destructive effects of chlorine disinfectants on the nucleic acid of novel coronavirus, and to assess the feasibility of real-time fluorescent quantitative PCR technology for the evaluation of the disinfection effect of novel coronavirus. Methods A suspension quantitative inactivation test was used to observe the inactivation effects of different concentrations of chlorine containing disinfectants and different action times on the novel coronavirus. RT-PCR method was used to detect novel coronavirus nucleic acid for the disinfection effect evaluation. Results The chlorine disinfectants of 1 000 mg/L and 2 000 mg/L could destroy the nucleic acid of ew coronavirusafter application for over 30s. The chlorine disinfectant of 750 mg/L could destroy the nucleic acid of new coronavirusafter application for over 15min. Chlorine disinfectant of 500 mg/L could not completely destroy the nucleic acid of new coronavirusafter 30 min action. Conclusion The disinfection method stipulated in the national prevention and control plan using 1 000mg / L effective chlorine for the epidemic sites of new coronavirus for 30 minutes could completely destroy the nucleic acid of new coronavirus. The Real-time quantitative PCR can be used to evaluate the disinfection effect of new coronavirus.
