Video shows how easily coronavirus passes through the air – proving why it is so important to stay at home


A video released by researchers in Finland shows how easily the coronavirus can get through the air – further proving why it is so important to stay at home.

The UK is currently in its third week of foreclosure and the measures will be reviewed in the coming days.

However, it is very likely to continue as the battle to slow the spread of Covid-19 continues.

And animation from Aalto University researchers showed how a single cough could hang in the air for “several minutes”, spreading to infect others in the process.

Researchers looked at how extremely small respiratory particles are transported through the air after coughing, sneezing and even talking.

How coughing or sneezing starts

Their example shows a supermarket and a person coughing in a store aisle before showing how quickly the particles have spread through the store.

The animation was modeled on the air movement of aerosol particles smaller than 20 micrometers.

A dry cough, however, has a typical particle size of less than 15 microns.

Professor Ville Vuorinen said: “A person infected with the coronavirus can cough and move away, but then leave extremely small aerosol particles carrying the coronavirus. These particles could then end up in the airways of other people nearby. “

Jussi Sane, chief specialist at the Finnish Institute of Health and Welfare, said: “Stay at home if you don’t feel well and keep a physical distance from everyone.

“The instructions also include coughing up your sleeve or a handkerchief and taking care of good hand hygiene.

“Based on the consortium’s modeling, it is not yet possible to issue new recommendations directly.

“However, these results are an important part of the whole, and they must be compared with data from actual epidemic studies. “
