New York Gov. Andrew Cuomo and his health commissioner, Howard Zucker, had all but made such discharges mandatory. If a hospital determined a patient who needed nursing home care was medically stable, the home had to accept them, even if they had been treated for COVID-19. Moreover, the nursing home could not test any such prospective residents — those treated for COVID-19 or those hospitalized for other reasons — to see if they were newly infected or perhaps still contagious despite their treatment. It was all laid out in a formal order, effective March 25. New York was the only state in the nation that barred testing of those being placed or returning to nursing homes.
