I live in Central Europe and it is mandatory to wear masks in the streets now, as well as in shops and on public transport. No mask, you won’t be allowed in the shop or on the bus. I don’t know what happens with people who genuinely can’t wear a mask, but online shopping is pretty good here.
I was back in London the other week, and out of 12 people on a bus I caught, only two were wearing masks. Mask compliance was also low in shops. The vast majority of those not wearing masks were BAME, which surprised me, given the higher risk.
Where I live, the numbers have dropped hugely - more than halved from November’s figures, and now around 30-40 cases per 100,000. The number of deaths has also halved. November was when mask wearing everywhere became compulsory. We’ve also had complete lockdown and a curfew. Drastic measures, but they seem to be working.
