The scientists therefore strongly advise avoiding public spaces. Professor Ville Vuorinen of Aalto University in Finland says: “If you have to go to a shop, you go there as rarely as possible. Stay there as short as possible.”
Researchers at the Bauhaus University in Weimar have already shown the effect of the simplest face masks, as they currently have to be worn in Austrian supermarkets, on the distribution of the virus. They filmed the air movements after coughing and sneezing at hand, in the crook of the arm, with a mask and finally without any barriers. The results were clear.
