At community nucleic acid sampling sites, there will inevitably be different levels of population aggregation that can lead to transmission if an infected person is present. The proper distance is kept, the mask is correctly worn, the hand hygiene is achieved, and the spreading and contact spreading of spray can be effectively prevented. However, the subject needs to open the respiratory tract when taking samples, and aerosol is unavoidable. If the subject is poorly fitted, such as failing to expose the pharynx, or is strongly reflecting, the sampling time will be prolonged, and there is a risk of coughing, nausea, sneezing, and aerosol generation during this process. If there is a positive in the subject, the risk of generating infectious aerosols around the operating point is further increased. Although the sampling points are mostly set outdoors and the ventilation condition is better, the aerodynamic condition during sampling is difficult to evaluate, the population density control and the matching degree of the testees are variable, the aerosol spreading risk is not negligible, if the condition is limited, the sampling points have to be set indoors or in a semi-open environment, for example, in the condition that a community does not have a proper open air field, the weather is not friendly (rain, snow, heat, cold, sand storm, tropical storm and the like), and the aerosol spreading risk must be considered.
