Scientists show how easily coronavirus can spread in a supermarket


A video was published showing how easily a cough from coronavirus could pass through the air.

The UK is currently locked out as the COVID-19 epidemic continues.

As of 9 a.m. on April 9, 243,421 people had been tested, of which 65,077 were positive.

And of the people hospitalized in the UK who tested positive for the coronavirus, 7,978 unfortunately died.

But researchers in Finland show they have produced a video showing how the virus could hang in the air for “several minutes,” reports Wales Online.

Researchers Modeled How Cough Particles Traveled In A Supermarket

Researchers at Aalto University created the 3D model to examine how small respiratory particles are transported through the air after coughing, sneezing and speaking.

The animation shows a person coughing in a supermarket aisle before the particles spread quickly to other aisles in the store.

Researchers modeled the airborne movement of aerosol particles smaller than 20 microns.

For a dry cough, which is a typical symptom of the current coronavirus, the particle size is generally less than 15 micrometers.

The researchers added that extremely small particles of this size do not sink on the ground, but rather move in the air currents or remain floating in the same place.

Aalto University Assistant 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 added, “Stay at home if you are not feeling 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. “
