Anil Subba, a Nepali Uber driver from Jackson Heights, Queens, died just hours after doctors at Elmhurst Hospital thought he might be strong enough to be removed from a ventilator.

In the nearby Corona neighborhood, Edison Forero, 44, a restaurant worker from Colombia, was still burning with fever when his housemate demanded he leave his rented room, he said.

Not far away in Jackson Heights, Raziah Begum, a widow and nanny from Bangladesh, worries she will be ill soon. Two of her three roommates already have the symptoms of Covid-19, the disease caused by the coronavirus. Everyone in the apartment is jobless, and they eat one meal a day, she said.

“We are so hungry, but I am more terrified that I will get sick,” said Ms. Begum, 53, who has diabetes and high blood pressure.
