"They say, you know, it's a hoax," he said. "We hear this all the time."
Abbu has personally experienced patients who, even nearing death, remained in denial and continued to assert untruths about the pandemic.
"I've had two patients who have died and even right until the time that they died, they didn't believe that they had it," Abbu said.
"It's not as though we are trying to get the patient to acknowledge that they have COVID before they die. These patients are so much in denial, they are volunteering this information."
Abbu said one patient who didn't believe they had COVID-19 went home and later died. The family of another patient who died didn't believe it was due to COVID-19 and asked if they could have an autopsy to confirm, he said.
