Coronavirus: Dozens more COVID-19 cases confirmed as Diamond Princess quarantine ends

Another 79 people have tested positive for COVID-19 on board a cruise ship that has been quarantined for two weeks - as passengers and crew started disembarking.

The new cases were confirmed as the controversial quarantine ended on the Diamond Princess, bringing the total on the ship to 621.

443 people were allowed to leave the ship on Wednesday, and about 2,000 others will be gradually evacuated by Friday.

The ship is currently moored off the coast of Yokohama in Japan, and the Foreign Office is hopeful that affected Britons will be able to get a flight back to the UK later this week.

Officials have warned British passengers and crew they may not be able to get on the plane if they leave the ship - and they will need to complete another 14 days of isolation when they land in Britain.

Other countries have sent flights to evacuate people from the ship already, with the US flying more than 300 nationals on Monday.

Australia is due to fly 169 out of the 220 Australians who were on board to Darwin, while six South Koreans and one Japanese spouse were flown to South Korea on Wednesday.

Passengers who have tested negative for the coronavirus and have no symptoms must have their body temperature checked before they are allowed to disembark.

Vicki Presland, an Australian tourist on board the Diamond Princess, said she was "very keen to get off this ship" after being confined to her cabin.

British tourists Allen and Vanessa Sandford have published videos of how they quelled their boredom during the quarantine, showing them pacing up and down their cabin, watching films and making their bed.

A Japanese infectious disease specialist, who spent a day as a volunteer doctor on the cruiseliner, has criticised his government's handling of the outbreak on the ship, saying it was run by "bureaucrats" instead of disease experts.

In a YouTube video that has garnered more than one million views, Kentaro Iwata said: "The cruise ship was completely inadequate in terms of the infection control.

"There was no single professional infection control person inside the ship and there was nobody in charge of infection prevention as a professional. The bureaucrats were in charge of everything."

Some people in their ship cabins waved farewell from their balconies as fellow passengers returned to dry land, with soldiers helping to escort the elderly.

A 77-year-old Japanese man, who disembarked with his wife, told Kyodo News: "I'm a bit concerned if I'm okay to get off the ship, but it was getting very difficult physically. For now, we just want to celebrate."

Crew members, who have continued working throughout the two-week quarantine period, are expected to stay on the ship.
