新型冠状病毒在环境中的存活潜力和感染风险

新型冠状病毒肺炎(COVID-19)传播速度快、范围广,主要通过飞沫和接触传播.本研究通过整理新型冠状病毒(SARS-CoV-2)在不同物体表面的存活时间及主要影响因素的相关研究,发现SARS-CoV-2的稳定性与重症急性呼吸综合征冠状病毒(SARS-CoV)相近,室温下可在多种物体表面或介质中存活数天(不锈钢表面2 ...

Survival potential and infectiousness of SARS-CoV-2 in environment

Coronavirus disease 2019(COVID-19)spreads rapidly and widely in the world,which is mainly transmitted through respiratory droplets and contact with contaminated media.In this study,SARS-CoV-2 was found to have a similar stability to severe acute respiratory syndrome coronavirus(SARS-CoV)by analyzing its survival time on different subject surfaces and main influencing factors in related research.SARS-CoV-2 can survive for several days at various subject surfaces or media at room temperature(stainless steel:2 days,plastic:3 days,glass:4 days,etc.),and SARS-CoV-2 can persist for longer time at low temperature and low relative humidity,which has caused severe threat to public health and has posed severe challenges to the prevention and control of COVID-19.According to available data,SARS-CoV-2 has the characteristics of high infectiousness and high covertness,similar to influenza A virus.By understanding the survival potential and infectiousness of SARS-CoV-2 in environment,targeted disinfection and effective protection can be implemented to reduce the incidence of COVID-19.
