Dr. Steve Kasspidis, of Mount Sinai Queens in Astoria, told Sky News that the daily routine of treating infected patients has become increasingly grim.

“People come in, they get intubated, they die, the cycle repeats,” he said. “The system is overwhelmed all over the place.”

“9/11 was nothing compared to this,” he added. “We were open waiting for patients to come who never came, OK? Now they just keep coming.”

A 55-year-old lab tech at Mount Sinai West in Manhattan, who declined to give her name, said “everyone is scared” — and also compared the pandemic to the 2001 terrorist attacks.
