1 December 2022. COVID 19: Returning to indoor mask requirements in Los Ángeles County. "There is this common line of thinking that the pandemic is over and COVID is no longer of concern, but these numbers clearly demonstrate that COVID is still with us," Ferrer said. Here in the stupid US, particularly San Francisco, I was on the Metro yesterday and most people were not wearing a face mask on crowded Metro trains. The older guys were masked. But of course the 20s-30s age group who think they are invincible and above it all, were not masked and don't care if they share their COVID with other people. Insanity. Since some people have no symptoms and don't know they're spreading COVID. Some would say, "But I'm fully vaccinated." That doesn't make any difference. It helps, but one can still get COVID and spread it. Most in the US are not getting the latest booster.
