Unlike the majority of European countries, in Sweden the mask is not compulsory.
In Stockholm, few wear it.
This strategy is defended in particular by the Swedish epidemiologist Anders Tegnell.
: "There is no reason to introduce something like this, and we continue to follow the development of dissemination in Sweden and the development of knowledge about the real effect of face masks".
In recent months, Sweden had distinguished itself from other European countries by not confining its population and by keeping cafes, restaurants and businesses open.
Only social distancing measures and regular hand washing were recommended.
A questionable assessment according to some figures, because with more than 5,800 dead and 84,000 cases of Covid-19, Sweden is among the countries most affected in relation to its population.
But unlike other European countries, Sweden has not seen an upsurge in the virus since June.
