The US states of New York, New Jersey and Connecticut will require visitors from Covid-19 hotspots elsewhere in the country to quarantine for 14 days, officials have said.
The governors of the three north-eastern states - once coronavirus hotspots themselves - announced the joint travel advisory today.
New York Governor Andrew Cuomo said he did not want visitors from other states bringing Covid-19 in with them, because "we worked very hard to get the viral transmission down".
The quarantine rule will apply to visitors from states where 10% of the population is infected with Covid-19 on a seven-day rolling average, Mr Cuomo said.
Nine states, including Alabama, Arkansas, Arizona, Florida, North Carolina, South Carolina, Washington, Utah and Texas..
The quarantine will come into effect on Thursday.
