I think the biggest challenge is that we don't yet have a really good grasp of what activities drive infection and which do not.  I remember in March, this one guy put a youtube video on how to decontaminate groceries where he basically used aseptic technique, with a "dirty zone" and a "clean zone" and really thorough cleaning with dilute bleach, and proper disposal and cleaning of anything that had been in the "dirty zone".  At the time it seemed like an overkill, but I remember wondering whether maybe it wasn't, if fomite transmission was common and easy.

At the same time, we think masks are effective at mitigating infection transmission, but we don't know how effective they are.  Do they reduce infection by 25%, 90%, or 99.9%?  So, if you are with someone wearing a mask, are you basically safe, or are you still at risk?

I think we have a better feel for what is risky and what is safe, but it is still not perfect.  We are probably doing some things (or avoiding some things) that don't material reduce our risk, but unfortunately, we don't know for sure which activities these are.
