US President Donald Trump has said quarantining New York “will not be necessary”, after the state’s governor said doing so would be “preposterous”.
Mr Trump said the latest decision was taken on the recommendation of the White House Coronavirus Task Force.
The president had earlier said he might impose a quarantine on New York, and parts of New Jersey and Connecticut, to slow the spread of Covid-19.
There are more than 52,000 cases in New York.
The state has about half of the total confirmed Covid-19 cases in the entire US.
Mr Trump tweeted that instead of quarantine, a “strong travel advisory” would be issued to New York, New Jersey and Connecticut by the Centers for Disease Control and Prevention (CDC).
The CDC then published a statement urging residents of those three states to “refrain” from all non-essential domestic travel for 14 days.
The agency said the advisory did not apply to “critical infrastructure” service providers, including healthcare professionals and food suppliers.
Speaking to reporters earlier on Saturday about the situation in New York, Mr Trump said: “We’d like to see [it] quarantined because it’s a hotspot… I’m thinking about that.”
