It is well recognized that Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) virus could be spread through touch and large droplets. However, we may have under-estimated the disease transmission by small droplets or aerosols that contain SARS-CoV-2 virus. Social distancing in public transport vehicles, such as airplanes, is not feasible. It is also not possible to wear masks in restaurant. This paper recommended wearing masks in airplanes and use partition screens in the middle of a table in a restaurant to reduce the infectioncausedbySARS-CoV-2virus. Advanced ventilation systems, such as personalized ventilation and displacement ventilation, are strongly recommended for transport vehicles and buildings.

众所周知，严重急性呼吸系统综合症冠状病毒2（SARS-CoV-2）病毒可以通过接触和大液滴传播。但是，我们可能低估了包含SARS-CoV-2病毒的小液滴或气溶胶对疾病的传播。在诸如飞机之类的公共交通工具中进行社会隔离是不可行的。在餐厅也不能戴口罩。本文建议在飞机上戴口罩，并在饭店桌子中间使用隔断屏风，以减少SARS-CoV-2病毒引起的感染。强烈建议将先进的通风系统（例如个性化通风和置换通风）用于运输车辆和建筑物。
