While most supermarkets have imposed social distancing measures, a new study suggests that they may not be enough to stop the spread of the virus.
Researchers at Aalto University have found that a single cough can spread the coronavirus across an entire supermarket.
In the study, the researchers looked at how extremely small respiratory particles are transported through the air after coughing, sneezing and even talking.
The team modeled a scenario where a person coughed in a supermarket aisle, and surprisingly found that the particles spread quickly in the supermarket.
Professor Ville Vuorinen, the author of the study, said, “A person infected with the coronavirus can cough and move away, but leave behind extremely small aerosol particles carrying the coronavirus. These particles could then be found in the airways of other people nearby. “
Based on the results, the researchers urge the public to stay home if they feel unwell.
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. “
