摘　　要：新型冠状病毒肺炎疫情暴发初期,对严重急性呼吸综合征冠状病毒2(SARS-CoV-2)易感人群、传播方式、传播力度认识的不足,是导致医务人员感染的主要原因。目前,已知SARS-CoV-2除通过直接接触和飞沫传播外,尚有气溶胶传播的风险,即在有限的空间内,病毒通过空气流动,从呼吸道进入人体肺部,进而造成感染。文章对病毒气溶胶基本特性及传播扩散机制相关研究进展进行综述,阐述防范SARS-CoV-2气溶胶在实验室、病区等密闭空间传播的重要性。At the beginning of the outbreak of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection,the lack of understanding of susceptible population,mode of transmission and intensity of transmission is the main factor leading to the infection of many medical staff.In addition to direct contact and droplet transmission,there is also a risk of aerosol transmission,that is,in a limited space,the virus flows through the air,enters lungs from the respiratory tract,and then infects each other.This review focuses on the research progress on the basic characteristics and spread mechanism of virus aerosol,and expounds the importance of the spread and prevention of SARS-CoV-2 aerosol in confined space,such as clinical laboratories and inpatients areas.
