TOKYO, Feb. 28 (CNN) - A British man who was aboard the quarantined Diamond Princess cruise ship and another woman has died from the novel coronavirus, according to Japan’s Health Ministry on Friday.

He is the first British citizen to die since the virus outbreak.

The man remained in Japan receiving treatment, as dozens more British passengers who were found not to have the virus were evacuated back to the UK while the woman is in her 70s.

The American-owned cruise ship was put under quarantine by Japan after a coronavirus outbreak was detected on board.

At least 705 people contracted the virus during the quarantine. For a time, the ship had the largest concentration of cases outside of mainland China, where the virus is thought to have originated.

Japan has now confirmed 11 deaths from the coronavirus.
