Triage tents are being installed in New York’s Central Park to operate as a field hospital.
A naval hospital ship has also docked in New York Harbour, carrying 1,000 beds and 12 fully-equipped operating rooms.
The state has recorded the highest number of cases and deaths in the United States, but Governor Andrew Cuomo is warning no Americans are immune.
“Anyone who says this is a New York City-only situation is in a state of denial. You see this virus move across the state. What is happening to New York is not an anomaly,” says Mr Cuomo.
The number of people who have died in New York state alone has exceeded 1,200 and increased by 965.
