Question.
If you would now hear about one new diagnosis within the frum community who them spread it to 10 people, would that be the same or different from that attorney and why
No , if one frum person infected ten that would not at this point bring on that level of concern. Very different at this point. At the time that attorney tested positive Wuhan had just given us a glimpse of how virulent Covid was, and cases had started popping up around the globe despite containment efforts. It was a given to anyone closely following the global pattern that the frum community with its extreme exposure to each other on so many levels, amplified by Purim, would be hit hard.
At this point even if there was a flare up of ten people you are dealing with a frum community that was as about as exposed as it could be around purim. Identical exposure would hardly replicate the wave of infections that hit then, especially considering the precautions that the vulnerable, and to some degree even most of the young and healthy among us are taking.
If you would hear of a similarly exposed population being hit with a new wave despite all, and indications were that the frum community would likely be next, then absolutely I would advocate that immediate measures be taken.
