Two young British holidaymakers have been forcibly quarantined in a "prison-like" Vietnamese hospital after a passenger on board their plane tested positive for the Coronavirus.

They were among dozens of passengers who flew from London to Hanoi last week who have been found by authorities and shut in hospitals and hotel rooms.

Friends Sam Carroll and Ciara Diver, both in their early twenties, were tracked to their holiday resort in Ha Long Bay by authorities days after disembarking from the plane.

52 passengers from the flight are thought to have visited Ha Long since disembarking, and around 300,000 residents have now been told to complete a health declaration after undergoing a health check.

Mr Carroll, from Richmond, London said: "We are in quarantine and have just been told that even if we don't have it we might have to stay here for two weeks."

Conditions in the hospital are less than desirable, and the pair are concerned they cannot communicate with the staff, who do not speak much English.
