Rohan Aggarwal, 26, a resident doctor treating patients suffering from the coronavirus disease (COVID-19), looks at a patient's x-ray scan during his 27-hour shift at Holy Family Hospital in New Delhi, India, May 1, 2021. "If a patient has a fever, and I know he's sick but he's not requiring oxygen, I can't admit him," said Aggarwal. "That's the criteria. People are dying on the streets without oxygen. So people who don't require oxygen, even if they are sick, we don't admit them usually," he added. "Another choice is I have an old male and I have a young guy. Both are requiring high-flow oxygen; I have only one bed in the ICU. And I can't be emotional at that time, that he is a father to someone. The young have to be saved."
