CDC investigates new cruise ship outbreak after dozens report gastrointestinal illness

The outbreak occurred during a voyage from Jan. 11 through Feb. 1 on a Regent Seven Seas Cruises ship.

The cruise line notified the CDC of the illnesses during the sailing - and the agency listed the cause of the outbreak as unknown.

The outbreak was reported on the cruise line's Seven Seas Mariner.

The vessel departed from Miami and was sailing to Honolulu.

A total of 631 passengers were on board the ship at the time.

The CDC said the cruise line took multiple steps to limit the spread of illness on board.

The CDC asked passengers who reported symptoms to provide stool samples, so health officials could test for a possible cause of the outbreak.

The agency said laboratory testing was still pending.

Fox News Digital reached out to Regent Seven Seas Cruises for comment.

Fox News Digital previously reported on the first confirmed norovirus outbreak of 2026.

That outbreak occurred on a Holland America Line cruise and left nearly 90 passengers and crew members ill during a voyage that ran from Dec. 28 through Jan. 9.
