>> People should ask their ONE rav and their ONE doctor.
this is not always true. Specifically, in a case of unknown entity like a new virus, it is prudent to ask multiple doctors and take into account the worst case. this is according to Rav Twersky above, some other poskim, and Dr. AAQ himself. If your Rabbi is making this mistake before paskenining, please explain it to him. Some local Rabbis here initially tried that – just call their friendly frum doctor form a well-known institution. This is still daas yahid.
