About the "at home" statistic. What proportion of the population is staying at home? If it's say 90%, then even if the case rate among these people is five times lower than among the people who are not staying home, there will still be more 'at home' cases. Also, there's a big risk of bias - people who are in risk groups are more likely to stay at home, because they know that it would be dangerous for them to go outside.

I'm not saying that there's nothing to the statistic, just that we have to be very careful about how we interpret things, and make sure that we think about the contextual factors.

Generally speaking though, I also think elevators should be taken into consideration more. I haven't heard much about recommendations regarding elevators, but surely it would help if people take the stairs as much as possible? I always take the stairs since the pandemic started, even the few times I've been to the office, which is eight floors up. Granted, a lot of people can't take the stairs because of health issues or because it's just too many floors, but those of us who can, should.
