Regarding masks, the false security is really coming to light. At one of my customers, they are extremely anal about screening and masks and sanitizing. I work there about three days a week, and one time I lowered my mask slightly to drink from a bottle of water, and a safety engineer came running up and said "You have to wear you mask at all times, no exceptions! If you need to eat or drink, you have to go outside or to one of the controlled break rooms".
Anyway, all was good until last week when five engineers turned up positive. They were not partying at bars, they don't hang out after work, and it was determined that it had to have come from the workplace. They all wore mask 100% of the time and social distancing was a minimum of 10 feet where they work and it was well ventilated. But even a quality medical mask lets 30% of particles through, and these particles will be the ones that are light and float around. People who are vulnerable and go out to eat and shop in public are kidding themselves. Of course a mask helps, but it's just common sense that anything but a respirator is going to let the virus out, as it did at this plant. If I was overweight or diabetic or had underlying respiratory issues, I wouldn't leave the house.
