How to avoid infection by subway and elevator? Japanese program measurement: this position is the safest.

Up to now (3/4), 42 cases of new coronary pneumonia have been diagnosed in Taiwan Province Province, among which people with unknown causes are infected. Although it has not reached the standard of community communication, many experts have suggested that the previous propaganda that "healthy people don't need to wear masks" is no longer applicable, and it is better to wear masks as much as possible when going out.

How to protect yourself when you are away from home? As the epidemic continues to heat up, although everyone tries to reduce going out, they still need to go out to work every day, and it is inevitable to take public transportation, such as MRT, train and high-speed rail.

Japan's Fuji TV "Live news!" I invited Katsumi Shanshui, an associate professor at Kyoto University of Industrial Fibers, to analyze the spread of the virus in subway cars.

The program measures how the virus spreads in the car. Associate Professor Shanchuan said that "the spread of the virus will be affected by air conditioning", which means that the virus in the car will spread through central air conditioning.

Image source: official website, cut from FNN, said that "standing near the car door" is the most dangerous place, because when passengers stand near the car door in a crowded way, the air conditioner will be difficult to open and the virus will concentrate on the crowd.

Image source: official website, cut from FNN, usually sinks and lands near the passenger's head due to its large size. At this time, if you touch your eyes, mouth and nose, you may be infected. On the contrary, it is safer for passengers to sit in their seats.

Image source: FNN official website elevator is the safest and most common enclosed space in the elevator station. Professor Shanchuan said that because the space in the elevator is very uniform, the infection risk of each passenger is not much different in theory.

Image source: Cut from FNN official website, but it should be noted that people who want to go to higher floors or stay for a long time will be safer to stand in the innermost position, because when someone coughs or sneezes, droplets will spray forward, and standing in the back position can relatively reduce the chance of infection.
