The mayor of New York City, the epicentre of the nation's coronavirus epidemic, on Sunday described the outbreak as the biggest domestic crisis since the Great Depression and called for the US military to mobilise to help keep the healthcare system from becoming overwhelmed.
"If we don't get more ventilators in the next 10 days, people will die who don't have to die," said Mayor Bill de Blasio, as the nation's most populous city saw COVID-19 cases top 9,600 and deaths climb to 63.
New York Governor Andrew Cuomo urged the federal government to take over acquisition of medical supplies so states do not have to compete with each other for desperately needed resources.
Help is not coming quickly enough, Cuomo said.
"Time matters, minutes count, and this is literally a matter of life and death," he said. "At the same time, there is not going to be chaos, there is not going to be anarchy. Life is going to go on. Different. But life is going to go on."
Cuomo gave New York City officials 24 hours to come up with a plan to deal with residents still congregating in parks and other places and not practicing social distancing.
De Blasio said New York City was not getting needed medical supplies from the federal government to contend with the rapid spread of the sometimes deadly illness.
