Cruise Royal Caribbean says virus not reason for Anthem return By Tom Stieghorst / February 29, 2016 Share 1 -- Royal Caribbean International said an occurrence of norovirus on the Anthem of the Seas is not the reason for the ship's early return to Cape Liberty in New Jersey.The ship is returning two days early from its current cruise and is expected to dock March 2 rather than its scheduled return of March 4.On Feb. 27, Royal Caribbean said it would cut the cruise short and return to port citing a storm threat. “We’ve been watching a large storm off the coast of Cape Hatteras,” the company said. “We want to be extra cautious when it comes to weather in the area."The decision follows Anthem’s encounter with a stronger-than-expected storm off the Carolina coast on Feb. 7 that left four passengers with injuries and damaged cabins and public areas. Royal called off the balance of that cruise, citing the potential for further bad weather, and returned to Cape Liberty.In a tweet this morning, Royal acknowledged that some passengers are showing norovirus symptoms. It said about 10 passengers per day have fallen ill on the cruise which left New Jersey on Feb. 21. “Didn’t affect decision to return,” the tweet said.Royal said about 6,000 people are aboard the ship.
