US President Donald Trump has said he is considering imposing a quarantine on New York in a bid to slow the spread of the coronavirus.
"We'd like to see [it] quarantined because it's a hotspot," he told reporters. "I'm thinking about that."
He spoke as confirmed cases in the state increased to more than 52,000, with at least 728 deaths.
But the state's governor, Andrew Cuomo, said he had not discussed such measures with the president.
"I didn't speak to him about any quarantine," he told reporters shortly after he held a call with Mr Trump.
"I haven't had those conversations," he added. "I don't even know what that means."
