A couple from Northamptonshire who tested positive for coronavirus been diagnosed with pneumonia.
David and Sally Abel were on board the Diamond Princess cruise ship in Japan for their 50th wedding anniversary.
The couple were placed in quarantine for two weeks on the ship, where four Britons have caught the illness.
Mr Abel has now been diagnosed with acute pneumonia, while Mrs his wife has mild pneumonia.
The family of David and Sally Abel said they have now been moved to a "prison"-like hospital.
Steve Abel, their son, posted video updates on the couple's YouTube channel alongside his wife Roberta on Friday night and Saturday morning.
He said the pensioners were left in a hospital room that has no shower or bathing facilities, and only provided with basic paper towels.
Speaking on Friday evening, he said: "They are in a really bad way.
"Dad is very weak. He can't walk around - he's in a wheelchair now. I haven't seen him in a wheelchair, but mum tells me he has to be put in a wheelchair to go from the ambulance to the hospital.
"They are really distressed. His exact words to me were, 'this has to stop now, we can't take any more of this. It's like a prison."'
"They haven't eaten properly. Neither of them can eat the food."
The news comes as a repatriation flight carrying 32 British and European evacuees from the cruise ship lands back in the UK.
Passengers will now be taken by road to Arrowe Park Hospital on the Wirral, where they will be placed in quarantine for 14 days.
So far, none of the 32 have tested positive for Covid-19
In a statement issued after the plane landed, Foreign Secretary Dominic Raab said: "We have brought 32 British and European citizens safely home from.
"The FCO worked hard to get them back to the UK securely.
"Our number one priority has consistently been the health and safety of UK nationals."
