Nearly 1,700 passengers on a Royal Caribbean 'cruise-to-nowhere' from Singapore were told to stay in their cabins after a Covid-19 case was detected on board, forcing the Quantum of the Seas ship back to port, authorities said.
All passengers had cleared a mandatory polymerase chain reaction test for Covid-19 up to three days before the cruise started on Monday, the Singapore Tourism Board (STB) said.
The infected passenger, an 83-year-old man, had reported to the onboard medical centre with diarrhoea, and others on board were told of the infection early today.
Royal Caribbean and the STB said all guests and crew of the ship who had close contact with the infected guest had subsequently tested negative for the virus.
