As part of its coronavirus restrictions, Hong Kong has restricted cruises to short trips in nearby waters, with ships asked to operate at reduced capacity and to only allow vaccinated passengers who test negative for the virus.
The Spectrum of the Seas ship had about 2,500 passengers and 1,200 staff on board. The nine close contact passengers were isolated from the rest of the people on board and preliminary tests taken during the journey returned negative results, authorities said.
“Spectrum of the Seas is taking appropriate measures under guidelines by the Department of Health,” Royal Caribbean told Reuters in a statement.
The ship, which in October was prevented from departing on a similar journey due to coronavirus fears, returned to the terminal early on Wednesday.
The nine close contacts will be sent to a quarantine centre, while the rest of the passengers and staff will have to undergo several compulsory tests in coming days, the government said.
Additionally, people who have been to 47 places across Hong Kong around the same time as the close contacts of recent patients have been issued compulsory testing notices, the government said in a separate statement.
The venues include the central Victoria Park, the newly-opened M+ modern art museum, ferry piers, restaurants, stores, clinics and others.
