My cousin, who is a member of Hatzolah, stopped by my house on Shabbos. He stopped wearing a mask or maintaining any distancing (except where legally required). The only symptom he had at a certain point was loss of smell. He told me that he and his brother visit their elderly (as in over 90 year old) father daily. He was one of those who told me that the local doctor would have had the schools and shuls open if legally permitted.
