Yokohama: Japan has quarantined a cruise ship carrying 3,711 people and was testing those on board for the new Coronavirus on Tuesday after a former passenger was diagnosed with the illness in Hong Kong.

"Eight people on the vessel, which arrived at Yokohama Bay on Monday, have symptoms such as fever," top government spokesman Yoshihide Suga said. Television footage showed several quarantine officers boarding the Diamond Princess cruise ship at the port of Yokohama on Monday evening to check all 2,666 passengers and 1,045 crew.
