Using computer simulations, experts from China analyzed how space affects the behavior of viral particles. Yellmed.ru.
In particular, they found out how aerosol particles are dispersed when a coughing person walks in a narrow corridor and in an open space.
It turns out that narrow corridors increase the risk of coronavirus transmission.
Researchers have identified several ways for the particles to scatter.
In the first case, droplets of the virus separate from the moving person and form a clot of viral particles, resembling a ball, several meters behind the infected person. Such a "ball" is capable of hanging in a "stale" zone for a long time.

In open space, however, viruses take a different route. Suspended particles "stick" to the back of the coughing, forming a long, thin "tail" of SARS-CoV-2 virus particles, which gradually dissipate in the air.
"This poses a major challenge when determining a safe social distance in a narrow corridor where a person can inhale viral drops, even if the patient is far in front of him," the study authors note. "Children are especially at risk."
