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. Experts so far cannot agree if SARS-CoV-2 transmission could be airborne (Lewis, 2020) , via small droplets or aerosols, although research has shown the risk. Figure 1 shows the droplet cloud that may contain SARS-CoV-2 virus with and without a screen in the middle of a table in a restaurant. The air with displacement ventilation does not mix so that the risk of inhaling airborne infectious disease virus from a neighboring student can be greatly reduced. for a long time, everyone should wear a mask to reduce infection risk although the SARS-CoV-2 virus concentration in indoor air may not be very high. Wearing mask would help as it can reduce the exposure to SARS-CoV-2 virus in air.	./cache/cord-319236-gxcs77pl.txt	./txt/cord-319236-gxcs77pl.txt
