Abstract

Abstract:

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.

Key words: Severe acute respiratory syndrome coronavirus 2, Aerosol, Transmission route
