Much of the Bay Area, including Berkeley, is under "shelter-in-place" guidelines at least through early April. It's basically semi-compulsory social distancing: we're not locked in our houses, but we're only supposed to leave for grocery shopping, medical services, or to go on a walk (six feet distant from any fellow pedestrians).
The goal of all this is to "flatten the curve" of new coronavirus infections. It won't stop new infections, but it will spread them out so the medical system isn't overwhelmed.
I'm supremely lucky in that shelter-in-place isn't a huge burden on me -- I work from home anyway, and I'm enough of an introvert that I frankly don't leave the apartment as often as I should even under the best of circumstances. But society-wide this sort of living arrangement will be tough to maintain over a long period of time. Yet I don't have a clear sense of what sorts of conditions would signify it's safe to lift the guidelines and let public events (anything from sports to school) proceed again. Even if the guidelines work to flatten the curve, wouldn't it get pointy again the moment people started congregating in masses again?
Put differently: shelter-in-place and social distancing rules are a holding pattern. But it's not clear to me at least what we're holding for. Anybody have an answer to that?
