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.
