There was a great piece on the radio a week ago describing the "Swiss Cheese Defense" against COVID. Each thing we do to reduce transmission--testing, face masks, closing bars, etc--is like a single piece of Swiss cheese--it has holes. But if we stack multiple slices atop each other, every new slice reduces the chance of something getting through the holes. So just keep a few slices between you and COVID, and your chances are really good.
