Confirmed coronavirus cases in New York State have risen by nearly a third in one day to more than 15,700, as authorities warn of widespread medical supply shortages.
New York governor Andrew Cuomo revealed the new statistics on Sunday, suggesting cases in the state now account for about 5% of confirmed COVID-19 cases globally.
There have been 117 recorded deaths due to coronavirus - and the state is one of several to have ordered residents to stay indoors.
Mr Cuomo said the government was "literally scouring the globe looking for medical supplies".
There have been more than 8,000 cases confirmed in New York City alone, causing mayor Bill de Blasio to echo calls to the federal government for help.
He urged US President Donald Trump to use the military to move ventilators and medical equipment to crisis areas.
"It's bad and only getting worse," Mr de Blasio told NBC, begging for Washington to step in.
Mr de Blasio accused the president of "not lifting a finger" to help his hometown.
"If the president doesn't act, people will die who could have lived otherwise," he said.

Negotiators from Congress and the White House resumed top-level talks on a ballooning $1trn-plus (£864bn) economic rescue package, as President Trump tries to save the nation from the rapidly spreading coronavirus pandemic.
Mr Trump appeared confident about the nation's ability to defeat the pandemic soon, even as health leaders acknowledged the US was nowhere near the peak of the outbreak.
Nationwide, there were 32,717 cases and 409 deaths as the US overtook Spain as the country with the third-highest number of cases, according to Johns Hopkins University.
New Jersey and St Louis were added to a growing list of areas where residents were told not to go to work.
President Trump has defiantly pushed back against criticism he was slow to respond to the crisis, though he continues to send mixed messages as to what the federal government is doing.
In recent days, he invoked the Defense Protection Act, a rarely used, decades-old measure that allows him to marshal the private sector.
But on Sunday, officials said it had not actually been used to compel the private sector to manufacture supplies like masks and ventilators.
