Fourteen Americans who were evacuated from the quarantined Diamond Princess cruise ship docked in Yokohama, Japan, tested positive for the coronavirus on Sunday.
According to the New York Times and USA Today, the infected passengers were placed in segregated areas on a chartered flight that flew back to the United States. There was a total of 340 Americans on board, and had all been quarantined on the cruise ship in Yokohama for nearly two weeks.
The flight landed Monday morning at Travis Air Force Base in Fairfield, California, both outlets reported. All passengers on board will be placed in a 14-day quarantine.
The U.S. had previously confirmed 15 cases of coronavirus in the country. Now, that number is at 29.
On Feb. 6, Princess Cruises confirmed to PEOPLE that 20 passengers on board the quarantined Diamond Princess cruise ship had tested positive for the illness, including three Americans.
Of the previously confirmed cases of the coronavirus in the U.S., seven were in California. The other cases confirmed were in Seattle; Phoenix; Madison, Wisconsin; Chicago and Boston.
However, the CDC emphasizes that Americans should not panic, saying that the risk of contracting coronavirus is still “low,” with the relatively few cases in the U.S.
