That’s good news, can you say if no one wore a mask there would have been cases? maybe there would have been, no one knows for sure.
I don’t know.
All I know is three things:
First of all, the disease started one country away. Right next door.
Second of all, the country 100% locked down. Completely.
Everywhere closed. The only stores open, were groceries, and other food stores. Immigration stopped. The country closed down.
Third, every single person, everyone, everywhere, wore a mask.
Everyone.
For two months.
That seemed to break the disease.
That was however, pretty early in the breakout. It is tougher now, in the US, no question.
Someone claimed there is a country in Europe, which did NOT mask up.
They also have had good fortune.
