A commercial aircraft carrying 80 tons of gloves, masks, gowns and other medical supplies from Shanghai touched down in New York on Sunday, the first of 22 scheduled flights that White House officials say will funnel much-needed goods to the United States by early April as it battles the world’s largest coronavirus outbreak.

The plane delivered 130,000 N95 masks, 1.8 million face masks and gowns, 10 million gloves and thousands of thermometers for distribution to New York, New Jersey and Connecticut, said Lizzie Litzow, a spokeswoman for the Federal Emergency Management Agency. Ms. Litzow said that flights would be arriving in Chicago on Monday and in Ohio on Tuesday, and that supplies would be sent from there to other states using private-sector distribution networks.

While the goods that arrived in New York on Sunday will be welcomed by hospitals and health care workers — some of whom have resorted to rationing protective gear or using homemade supplies — they represent just a tiny portion of what American hospitals need.
