Kinda hard when reading this thread to not get caught up one way or the other, but just to try to lower the flames here a bit in the spirit of Rabbi Reisman's wise words posted upthread. It does not have to be all or nothing. Meaning, that while reasonable people can and do disagree (sometimes unreasonably
), there are actual doctors and competent Rabbis who maintain that in certain communities (Lakewood for example) the virus seems to have now run its course (at least for now). And there has been more than a few weeks of almost no social distancing (for better or for worse, thats just been whats going on especially with the kids) with no signifigant uptick. This would seem to allow for some lessening of restrictions.
And while I think they would all agree on the need to be vigilant for any sign of a re-bound, the current data (new infection rate, hospitalization etc.) being relayed by Hatzala and local medical facilities, tells a certain story for now. Of course vulnerable people need to be extra careful, and it would behoove everyone to continue with certain precautions- as relevant and possible, but we are clearly not in the same place now that we were before Purim.
And as an aside, please correct me if I'm wrong, but while I understand the reluctance of most doctors to say so outright (they and everyone have been fooled so much by everything about this novel virus and been wrong about so much so often), the overwhelming data seems to support the fact that those who have antibodies are almost certainly not going to catch it again (for at least a significant amount of time, let's not forget there are countries well ahead of us on this, and there has not been any significant reports of reinfection). So to say that only those who have antibodies should come to shul presents a whole different precaution level. (Of course there are other issues with that in cases where it effectively ends safe backyard minyanim for those not yet infected.)
