What happens when a person with Covid-19 coughs in a common space? That was the question that researchers from Aalto University of Finland were made and responded by conducting a 3D model of the behaviour of water particles emitted by coughing from a coronavirus infection.
The model takes into account the context of a supermarket, to demonstrate how coronavirus droplets can spread through the hallways and possibly reach others-through the suspension in the air of these particles for several minutes.
“Someone infected with the coronavirus can cough and walk away but then it leaves extremely small aerosol particles that carry the coronavirus. These particles could end up in the respiratory tract of other people nearby, “ explained the assistant professor at the Ville Vuorien study house.
According to the analysis of this model, after a cough, the virus droplets could travel up to two meters away.
The video created by the Finnish researchers took into account a number of factors, such as the store ventilation and particular weather conditions.
It is also important to know that the virus droplets end up diluting.
On the other hand, the World Health Organization has determined that the coronavirus is not spread through the air, except in very specific and reduced medical environments.
Finally, both the WHO and the Finnish Institute for Health and Well-being recommend stay home in case of discomfort and maintain a physical distance of at least a meter and a half from other people. Instructions also include coughing into the sleeve or handkerchief and constant handwashing with soap for more than 20 seconds.
