Royal Caribbean Group said today (December 20) 48 people on its Symphony of the Seas cruise ship tested positive for COVID-19, fueling concerns that the new Omicron variant of the coronavirus could put a damper on a recovery in the cruise industry.

The cruise operator said it had 6,091 guests and crew members on board the ship, which ended a week-long cruise in Miami on Saturday after setting sail on December 11.

The passengers who tested positive were asymptomatic or mildly symptomatic, Royal Caribbean said in a statement, adding that six guests were disembarked earlier in the cruise and transported home.

Royal Caribbean said 95 per cent of the community on board were fully vaccinated, while 98 per cent of those who tested positive were also fully vaccinated.

Symphony‘s future itineraries are not impacted, it added.
