3,700 trapped aboard cruise ship after coronavirus embarks arstechnica.com

Over 3,700 people on a luxury cruise ship now docked in Yokohama, Japan, are trapped aboard, with guests confined to their cabins for the remainder of 14-day quarantine after the 2019 novel coronavirus (2019-nCoV) joined them at sea.
Officials were clued into 2019-nCoV’s presence on the ship after a guest from Hong Kong tested positive on land.
There, he tested positive for the coronavirus on February 1, according to Princess Cruise Lines, which operates Diamond Princess and is owned by British-American cruise operator, Carnival.
As of February 4, the initial infected guest from Hong Kong was said to be in stable condition.
Also, another cruise ship, the World Dream, carrying about 3,600 passengers from China to Vietnam, is being held in Hong Kong for health screening.
