Nearly 20 percent of facilities in Japan that provide nursing care have run out of surgical masks amid the new coronavirus outbreak.

More than 1,000 care facilities across Japan responded to a survey over the weekend by the Nippon Careservice Craft Union.

Passengers have been disembarking from the coronavirus-hit cruise ship Diamond Princess. Nine-hundred and seventy people had left the vessel at its port in Yokohama near Tokyo in the 3 days through Friday. About 300 passengers and 1,000 crew members remain on board.

A 14-day quarantine period imposed by health authorities ended on Wednesday. People with no symptoms and who test negative for the virus have been permitted to leave.

Japan's health ministry says 99 more people on board the quarantined cruise ship Diamond Princess have tested positive for the new coronavirus.

The ministry said on Monday that of the newly found virus carriers, 85 are passengers and 14 are crewmembers.
