Two passengers, a man and a woman, who were aboard the Diamond Princess cruise ship have succumb to coronavirus. 

Both were in their 80s with underlying health conditions. 

According to the BBC, they were being treated in hospitals after being taken off the previously quarantined ship. 

The male victim was 87 and the female victim, 84. 

Though they have not been publicly named, officials say the man was from Kanagawa of Tokyo and suffered from bronchial asthma and the woman died from pneumonia that was believed to be caused by COVID-19. 

Japan's Health Minister, Katsunobu Kato, said both had been sent to medical facilities last week after showing symptoms. 

At least 621 people on the Diamond Princess tested positive for the virus, which made this particular group of infected individuals the biggest cluster outside China.

The virus, which originated in China's Hubei province in 2019, causes pneumonia-like symptoms. 

At this point, there have been a total of 2,118 deaths and nearly 75,000 confirmed infections recorded in mainland China.
