It's just flu, only a bit more contagious.
People die from flu every year, everywhere. Becase and only because it doesn't affect young people as much as the common flu, death-rate is a bit bigger as well. Symptoms are milder if we were to compare with the common flu.
Wearing a mask doesn't help you escape the flu. Masks help not spreading it if you already have it, but I assume that if you do, you won't go places.
It's a bit annoying how a darn flu got to be soooo bad.
People die from influenza everywhere, every year. We are mortals. Get used to it.
