New York Governor Andrew Cuomo has pleaded for medical supplies, warning Covid-19 is spreading in his state faster than “a bullet train”.
“The apex is higher than we thought and the apex is sooner than we thought,” Mr Cuomo told reporters on Tuesday.
He said the federal government was not sending enough equipment to combat the crisis, noting the state needs 30,000 ventilators.
New York now has over 25,000 confirmed virus cases and at least 210 deaths.
The World Health Organization (WHO) said on Tuesday the US could become the new epicentre of the coronavirus pandemic.
“We are now seeing a very large acceleration in cases in the US. So it does have that potential,” WHO spokeswoman Margaret Harris said.
Mr Cuomo’s warning comes as President Donald Trump suggested having the US back in business by early next month.
“We need federal help and we need the federal help now,” Mr Cuomo said.
New York currently has 7,000 ventilators, but needs 30,000, the governor said.
Mr Cuomo continued: “The [infection] forecaster said to me, ‘We were looking at a freight train coming across the country.’
“‘We’re now looking at a bullet train.'”
The state is also looking into creating more healthcare areas, possibly by turning college dormitories and hotels into makeshift hospitals.
With 25,665 cases in New York, the state accounts for more than half of all US infections.
The number of new cases in the state is doubling every three days, the governor said, and showing no sign of slowing down.
Mr Cuomo said the rate of infections could overwhelm the healthcare system. New York may need up to 140,000 hospital beds in a worst-case scenario, he said.
The governor also said he would not “put a dollar amount on human life”, in what was seen as an implicit criticism of Mr Trump’s concerns that measures to contain the virus could wreck the US economy.
“My mother is not expendable and your mother is not expendable,” said Mr Cuomo.
He said he was not willing to “sacrifice that 1 or 2%” of vulnerable people.
“We are going to fight every way we can to save every life that we can because that’s what, I think, it means to be an American.”
