BEIJING (AP) – Japan on Friday reported 41 new cases of a virus on a cruise ship that’s been quarantined in Yokohama harbor while the death toll in mainland China rose to 636, including a doctor who got in trouble with authorities in the communist country for sounding an early warning about the disease threat.

Following an online uproar over the government’s treatment of Dr. Li Wenliang, 34, the ruling Communist Party said it was sending an investigation team to “fully investigate relevant issues raised by the public” regarding the case.

Before Friday’s 41 confirmed cases, 20 infected passengers were escorted off the Diamond Princess at Yokohama near Tokyo. About 3,700 people have been confined aboard the ship.
