The 'rona spreads even among those masking, sticking close to home, and rarely going out for anything more than a visit to the grocery store. So, if the spread continues, they are either catching it from family members bringing it in, or from the grocery store.
Grocery store? We've known all along that the virus can hang in the air for many minutes. So, you step up to the cashier, breathing, of course, and if you have the virus, some of it probably escapes your mask. And, since it hangs in the air, the next person comes along and breathes it, some of it getting through their mask. In all that we've done, cannot we see we need to fix the air-flow systems in our stores? Yes, that is an expensive thing, but it needs to be done. The air needs to be either sucked downwards, and into a grate in the floor, or upwards into the ceiling and out. Or, cleaned before being recirculated.
We know these particles hang in the air. We've known that since March. Yes, masks work. But, they are not perfect. The spread continues, and this is one thing we should see that needs to be done. We should do it.
