10 more test positive for coronavirus from cruise ship quarantined off Japan

Ten more people aboard a cruise ship quarantined off Japan have tested positive for the novel coronavirus that has sickened more than 28,000 and killed more than 560 people in mainland China, Japan’s health ministry said Thursday.

That brings the number of people who have tested positive for the coronavirus from the Diamond Princess to 20. The ship is quarantined off Yokohama with around 3,700 passengers and crew aboard.

The first 10 were discovered in the first batch of testing, and the second 10 were confirmed after 71 more results were available, the health ministry said.

The ship has docked in Yokohama to disembark the 10 new cases and to load food and other supplies.

Of the newly confirmed 10, two are Americans — one a woman in her 60s, the other a woman in her 70s, health ministry officials said Thursday. Four are Japanese, two are Canadian, one is from New Zealand and one is from Taiwan.

The other 10 were previously identified by Princess Cruises as two Australians, three Japanese, three from Hong Kong and one from the U.S., as well as one Filipino crew member. They have been taken to hospitals.

A person from Hong Kong had been on the ship and later tested positive for novel coronavirus, which set off testing for 273 people who either showed symptoms or had close contact with that patient.

More Americans from Wuhan arrive in the U.S.

Hundreds of U.S. nationals, who were extracted from locked-down Wuhan, arrived in the U.S., a U.S. official familiar with the situation told NBC News.

Two planes carrying the Americans from Wuhan, the center of the novel coronavirus epidemic, arrived at Travis Air Force Base, southwest of Sacramento, California early Wednesday morning.

The passengers will be subjected to a 14-day quarantine upon arrival, U.S. Northern Command said earlier in a tweet.
