These Supercomputer Simulations Depict How COVID-19 Spreads At A Table

At the beginning of this month, the guidelines for COVID-19 were revised by the Center for Disease Control and Prevention. They stated that the infected particles of disease could stay in the air for minutes to hours and spreads between two individuals, who are more than 6 ft/1.8m apart.

Now a recent simulation has appeared showing exactly how the virus spreads at a dinner table.

The simulation run by Japanese researchers on a supercomputer called Fugaku depicted a scenario where four people are seated at a dining room table facing each other. The research established that when speaking to the person seated in front of them, about 5% of droplets got to the individual.

When speaking to the person positioned diagonally, only a quarter of the amount traveled. By turning sideways to talk to the person settled right next to the individual, more than 25% of droplets reached the person.

They also inspected situations of droplet transmission based on humidity levels. Strangely, the scientists found out that fewer droplets were spread when the humidity level was high. 

The experiment is a disgusting but efficient depiction of showing how harmful having dinner conversations without masks are. It is also a way of reminding how important social distancing is.
