Hundreds of people evacuated from the quarantined cruise ship Diamond Princess in Japan arrived in the United States on two chartered flights late Sunday and early Monday.

The planes landed at Travis Air Force Base in Northern California and Lackland Air Force Base in Texas, and passengers will now face another round of quarantine - though this time on land.

The U.S. quarantine will last 14 days, which follows their shipboard confinement that began Feb. 3.

The passengers were offered evacuation due to the high risk of the virus, the U.S. State Department said.

A total of 340 U.S. passengers were transported from the cruise ship to Haneda airport in Tokyo.

Some U.S. citizens opted to remain on the ship to avoid another quarantine or the chance they might catch COVID-19 from other evacuees. 

On Monday, Japan said that there were an additional 99 coronavirus cases diagnosed on the ship, bringing the total number of infected to 454 -- about 1 in 8 of the original passengers and crew on board.

Of the newly evacuated U.S. citizens, 14 tested positive for the COVID-19 but were allowed on the flight to the United States because they did not show symptoms.

U.S. officials said those passengers were kept isolated on the flight.

Similar evacuation flights are planned to return other passengers to Australia, Canada, Italy and Hong Kong.
