More than 10 medical personnel were seen boarding a cruise ship docked at Yokohama Port on Saturday morning as the vessel has been quarantined in the wake of a coronavirus outbreak.

Some passengers could be seen exercising on the deck of the Diamond Princess, while others enjoyed the views.

Japan' health minister Katsunobu Kato says 39 more people on board a cruise ship at the port of Yokohama have been found to be infected with the new coronavirus. A quarantine official has also been infected separately.

Kato told reporters on Wednesday morning that the new infections were confirmed from 53 people tested. This brings the total number of passengers and crew infected on the vessel to 174 out of 492 people tested.
