Japanese officials said that the total number of confirmed Covid-19 cases on the Costa Atlantica cruise ship has increased to 91.
The testing has been completed for half of the crew onboard.
Yesterday, officials reported that the total number of cases on the ship increased to 48.
The ship is docked in a shipyard in Nagasaki and is undergoing repairs.
The ship only carries crew and was transported by Mitsubishi Shipbuilding in February when the repairs could not be carried out in China due to the outbreak.
The crew on the ship was not allowed to leave the wharf after the ship arrived in Japan. However, it was reported that some of the crew had gone outside the restricted area.
A Nagasaki official said that only one of the infected crew members is in the hospital, while the remaining crew is on board and is monitored by one doctor and four nurses.
Two other Costa Cruises ships, Costa Serena and Costa Neoromantica are also in Nagasaki and have a combined crew of approximately 1,000.
The ships are scheduled to depart by the end of this month and do not have any reported cases of Covid-19 onboard.
The infections on the Costa Atlantica cruise ship follow the outbreak on Princess Cruises’ Diamond Princess cruise ship, which was one of the major clusters of the coronavirus.
It was reported that approximately 700 confirmed cases and ten deaths were linked to Diamond Princess.
The pandemic has so far killed over 191,000 and infected more than 2.72 million people around the world.
