(CNN) — More than 3,000 passengers and crew were being held on a major cruise liner in Hong Kong on Wednesday morning after a Covid scare prompted authorities to order the ship to return to port.
Nine people on board Royal Caribbean’s Spectrum of the Seas, which was on a “cruise to nowhere” around the South China Sea, were identified as close contacts of a positive Covid case.
Roughly 2,500 passengers and 1,200 crew were told to remain on the ship to undergo coronavirus testing.
Royal Caribbean said it was informed of the close contacts on January 4 and subsequently tested and isolated these passengers, according to a statement posted to the cruise line’s Hong Kong Facebook page. The nine close contacts reportedly tested negative via PCR tests.
To sail on Spectrum of the Seas, passengers and crew were required to be fully vaccinated, to file a health declaration and to test negative within 48 hours of boarding. Unvaccinated children had to show a negative test and fill out a health declaration.

In its statement, the Hong Kong government said it was concerned the nine people may have been in contact with a positive Omicron Covid case.
Hong Kong reported its first Omicron coronavirus case last week, following nearly three months without any local cases.
Hong Kong has kept up strict border regulations and quarantine rules for the duration of the pandemic. Omicron slipping through the net has led to the government to clamp down further on travel, banning flights from Australia, Canada, France, India, Pakistan, Philippines, the United States and the United Kingdom effective January 8.
Local Hong Kong restrictions have also been implemented, with indoor dining banned and entertainment venues such as cinemas, museums and bars and clubs temporarily shutting their doors.
Future cruises to nowhere are also off the table for now.
Global cruising chaos
The move “reflects increases in cases onboard cruise ships since identification of the Omicron variant,” the CDC website says.
The industry body that represents the world’s major cruise lines, Cruise Lines International Association (CLIA), expressed disappointment at the CDC’s elevated risk level.
“The decision by the CDC to raise the travel level for cruise is particularly perplexing considering that cases identified on cruise ships consistently make up a very slim minority of the total population onboard — far fewer than on land — and the majority of those cases are asymptomatic or mild in nature, posing little to no burden on medical resources onboard or onshore,” the industry body said in a statement last week.
