Cases per day in my large London Borough are averaging about 2 or 3 a day. Yes 2 or 3. Single digits. Not 200 or 2000. Why on earth should thousands of people make themselves hugely uncomfortable in masks for that?? We seriously need to get a grip here.
That's because of lockdown! We had exponential growth before lockdown - that's why it was needed. The Covid virus started with 1 person and spread to millions. That's exponential growth. Your 2 or 3 would rise quickly to 200/300 and then to 2000/3000 if people don't carry on taking precautions. Yes, we can start to relax the lockdown, but EVERYONE needs to do their bit to stop it spreading again - that's means respecting personal distance, self isolation with symptoms, washing hands, etc etc.
