I forwarded the YT link that @simsa03 posted to my co-worker K, who lives in the vicinity of NYC. He said that he knows where the hospital in question is located.

Also, Mark said that someone working at his office (a man in his seventies) recently had pneumonia and had to leave the assignment. AFAIK, the man was not tested for #COVID-19. The staff is currently mostly working from their hotels, but they were not doing so at the time.
