Japanese scientists scared Web users by showing on the video what happens when someone in the room coughs without covering their mouth with a handkerchief or hand, writes Medialeaks.
Even high barriers will not save saliva from invisible particles, and in the subway, it seems better to go down now in a full set of personal protective equipment.
The world is gradually emerging from the coronavirus crisis, which means that people will soon have to get out of their homes and go to work. True, life will not be soon past: for example, Muscovites will not be able to part with masks and passes for a long time, and now they will have to walk only on schedule.
But those who can still get to their office may have to work for fear of contracting a coronavirus from one of their colleagues. And even after the video created by the staff of the Japanese Institute of Physical and Chemical Research RIKEN, even more so.
Scientists using computer graphics simulated the movement of microparticles flying out of a person’s mouth when coughing. The situation on the record imitates an office in which company employees are sitting at the same table opposite each other.
At the same time, the frames show that even the barrier installed in the center of the table will not save from droplets invisible to the naked eye.
Two people sitting opposite a coughing colleague seem doomed: a cloud of droplets of droplets in the video settles right on them.
Japanese researchers simulated another situation. They increased the height of the fence so that its upper edge was higher than the heads of workers.
But even if at the time of the ejection of bacteria all particles of saliva hit the barrier, then after the movement of air in the room it still applies to those who are sitting opposite.
As a bonding bonus, scientists have shown how microbes will spread in a filled subway car. Spoiler: Do not save anyone.
Scientists believe that even open windows will not help at rush hour: air will continue to circulate through the car without significant ventilation, so all passengers risk becoming infected.
The experiment’s video was posted on Twitter on NHK’s official account on June 4, and the video has already been watched over a million times.
