In Japan, a simulation was organized, the purpose of which was to figure out what happens when 4 people sit at a table with an area of 60 square meters. see in a restaurant and one of them is a carrier of COVID-19. The study was conducted by scientists from the Center for Computational Sciences of the RIKEN Institute together with colleagues from Kobe University, liga.net reports, citing The Asahi Shimbun.
The researchers looked at 3 key scenarios:
- when people sit opposite each other,
- when the ldi sit side by side
- and when people are placed diagonally.
By the time the experiment began, it was already known that when a person speaks, about 5% of the drops that he exhales reach the nearest interlocutor, and then microdrops spread to other people at the table.
According to the researchers, simulations of the Fugaku supercomputer showed that a person is more likely to contract coronavirus through droplets if he sits next to his partner and turns his head to talk than if they were sitting opposite each other.
So, it turned out that the man who was sitting next to him gets five times more drops than if they were sitting opposite each other.
A more successful seating scheme is diagonally opposite each other, the researchers note. When a person talks to someone diagonally across the table, they get about 75% fewer drops than in the previous scenario.
The researchers also note that diners can reduce the possibility of contact with droplets from others if they do not turn to talk to each other when they sit next to a restaurant counter.
To do this, the head of the research group Makoto Tsubokura, a professor of computer science at Kobe University, suggested that restaurants install mirrors in front of visitors so that they can communicate with each other safely.
The researchers also noted that the survivability of the virus in dry rooms is higher than in wet ones. Therefore, scientists advise to ventilate rooms, or use air humidifiers.
Be healthy!
We will remind, earlier we told how beet juice will help to improve health, and we were also surprised at what unusual cakes became popular in the past quarantine summer.
