SINGAPORE — A ship operated by Genting Cruise Lines has returned to Singapore port after a suspected COVID-19 case on board sparked a health scare. Some 2,900 passengers and crew members remain on board pending test results.

Singapore Tourism Board cruise director Annie Chang says a 40-year-old passenger was isolated Tuesday after being identified as a close contact of a confirmed case on land. She says he subsequently tested positive for COVID-19 on board the World Dream cruise ship, and has been sent to a hospital for further testing. His three travelling companions tested negative.

Chang says all leisure activities on board the World Dream cruise ship have ceased, with the vessel undergoing a thorough disinfection process after returning to port early Wednesday. All passengers are confined in their cabins until test results are out and contact tracing is completed.

Dream Cruises, a unit of Genting Cruise Lines, says the ship departed Sunday on a three-night cruise with 1,646 passengers and 1,249 crew members. The company says that as a precautionary measure, World Dream’s subsequent two-night cruise scheduled to depart late Wednesday has been cancelled.
