At Saint Joseph's Hospital in New York, U.S., coronavirus patients have accounted for more than 85 percent of all admissions in the last four weeks. About 140 medical staffs tested positive for COVID-19. "It's been a nightmare. We have a volume of sick people like you can't believe. In one shift, I pronounce six people dead," Dr. Anthony Leno, director of the Emergency Medicine of Saint Joseph's Hospital, sighed.
