PORT EVERGLADES, Fla. (AP) -- A Royal Caribbean International cruise ship has returned to South Florida, concluding a voyage that saw more than a hundred people develop a gastrointestinal illness.

The cruise line reported Friday that 105 of 1,991 guests and 3 of 772 crew members experienced a possible norovirus during the 11-night trip. Those affected by the short-lived illness have responded well to over-the-counter medication being administered onboard the ship.

The cruise line said in a statement that crew members conducted enhanced cleaning to help prevent the spread of the illness. After returning to port, crew members aboard the Vision of the Seas conducted an extensive and thorough sanitizing onboard the ship and within the cruise terminal to help prevent future illness.

The source of the illness wasn't immediately reported.
