摘要
Dear Editor,The severe acute respiratory syndrome coronavirus 2(SARS-Co V-2)is the causative pathogen of the pandemic coronavirus disease 2019(COVID-19),which has infected nearly 90 million people and resulted in 2 million human deaths by the end of the year 2020.SARS-Co V-2 can survive in aerosols or on the surfaces of various materials for up to 72 h(Ong et al.2020;van Doremalen et al.2020).In China,although the human-to-human transmission pathway is under well control,the fomite transmission pathway now accounts for a significant fraction of new infection cases.Therefore,environmental disinfection of public areas and workspaces potentially contaminated by SARS-Co V-2 is an important measure to control the spread of COVID-19 by fomite transmission.A disinfectant that is safe and readily available at a low cost is urgently needed to meet environmental disinfection requirements.
