Mask-wearing culture

At the beginning of the COVID-19 outbreak, people wearing masks were rarely seen on the street in many Western countries. They believed that face masks were only needed by special groups of people such as medical staff and the sick.

As the pandemic rages in Europe and the US, some countries and cities have rolled out mandatory rules or recommendations on wearing a mask in public.?

Now more and more people are wearing masks.
