TOKYO — Americans aboard a quarantined ship will be flown back home on a chartered flight Sunday, the U.S. Embassy in Japan said.

About 380 Americans are aboard the Diamond Princess cruise ship, which has docked at Yokohama, a port city southwest of Tokyo.

So far, 285 people from the ship have tested positive for a new virus.

The embassy said the aircraft will arrive in Japan late Sunday, and people will be flown to Travis Air Force Base in California, with some passengers continuing to Lackland Air Force Base in Texas.

After arriving in the U.S., all will need to go through another two weeks of quarantine.

The virus has infected more than 67,000 people globally and has killed at least 1,526 people, the vast majority in China. In the United States, 15 people have tested positive for the sickness, named COVID-19.
