Well as someone who caught covid along with my 2 colleagues at work and fortunately, although had mild symptoms though still very painful, took me 4 days to recover with very painful muscle ache in my upper back, I would highly recommend wearing a mask when in crowded areas like stores.
The UK variant is now in America and it will hit hard according to Michael osterholm who is an epidemiologist. People need to listen to scientific facts, not quacks. I remember watching Mr osterholm on Joe rogan back in early March 2020 and everything he said back then has happened in the US. He estimated that about 400000 people would likely die in the US by the end of 2020 and he wasn't far off. Wear your mask everyone and help save lives.
