基　　金：National Science Foundation of China(92043201). 摘　　要：What is already known on this topic?Aerosol transmission was one route for the spread of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)and usually occurred in confined spaces.What is added by this report?Aerosol transmission was found to exist between handshake buildings,i.e.,buildings with extremely close proximity that formed relatively enclosed spaces.Transmission was mainly affected by the airflow layout caused by switching air conditioners on and off as well as opening and closing doors and windows.What are the implications for public health practice?Centralized isolation and home isolation in handshake buildings creates a risk of SARS-CoV-2 aerosol transmission under certain conditions.Attention should be paid to the influence of air distribution layout on aerosol diffusion in isolation wards,and disinfection of isolation venues should be strengthened. 关键词：AEROSOL STRENGTHENED ISOLATION
