Two planes carrying hundreds of US citizens from a coronavirus-hit cruise ship have left Japan, officials say.
One plane has landed at a US Air Force air base in California, and its passengers will be isolated at military facilities for 14 days.
There were some 400 Americans on board the Diamond Princess. The ship with some 3,700 passengers and crew has been in quarantine since 3 February.
Meanwhile, China reported a total of 2,048 new cases on Monday.
Of those new cases, 1,933 were from Hubei province, the epicentre of the outbreak.
More than 70,500 people across China have been infected by the virus. In Hubei alone, the official number of cases stands at 58,182, with 1,692 deaths. Most new cases and deaths have been reported in Wuhan, Hubei's largest city.
What's happening to the Diamond Princess?
The cruise ship was put in quarantine in Japan's port of Yokohama after a man who disembarked in Hong Kong was found to have the virus.
On Sunday, Japanese officials said the number of infections on the ship had risen by 70 to 355, making it the largest cluster of cases outside China.
At least 40 US citizens who were on board are infected and will be treated in Japan, Dr Anthony Fauci, Director of the National Institute of Allergy and Infectious Diseases told US broadcaster CBS.
The two aircraft chartered by the US government left Tokyo's Haneda Airport in the early hours of Monday. The second flight was due to land at another base in Texas.
More than 300 passengers are being repatriated voluntarily, the US state department said. Fourteen of them were reported during transit to have tested positive for the virus and were being kept separate from the other passengers, it said.
Those entering the US will undergo a 14-day quarantine, on top of the time they have already spent confined on the ship.
"And the reason for that," Dr Fauci added, "is that the degree of transmissibility, on that cruise ship, is essentially akin to being in a hotspot."
Some of the Americans have declined to be evacuated, preferring to wait until the ship quarantine comes to an end on 19 February.
Passenger Matt Smith, a lawyer, said he would not want to travel on a bus to the plane with possibly infected people.
To assist with relief efforts, Japan's government has given away 2,000 iPhones to passengers on the ship - one for each cabin.
The smartphones were distributed so people could use an app, created by Japan's health ministry, which links users with doctors, pharmacists and mental health counsellors. Phones registered outside of Japan are unable to access the app.
Other evacuation flights have been arranged to repatriate residents of Israel, Hong Kong and Canada. On Monday, Australia announced that it would evacuate 200 of its citizens too.
