Scientists: after a conversation, the coronavirus “hangs” in the air for 14 minutes

Ejected from the mouth during a conversation, microdroplets of secretions containing coronavirus can remain in the air for up to 14 minutes, experts at the US National Institutes of Health warned. The study was published in the journal PNAS.

The authors of the work asked volunteers to pronounce certain phrases, and with the help of special lasers they measured how long the micro drops thrown out in the air would last in the air. As it turned out, in a minute of a loud conversation, a minimum of 1000 micro-droplets are formed that stay in the air for more than eight minutes, and in some cases up to fourteen.

The study did not take into account air movement, temperature changes, and other factors, scientists say. However, the very fact that the virus is able to stay in the air even for several minutes is a powerful argument in favor of the fact that infected people use masks.
