A cruise ship that reported an outbreak of a stomach virus is ready to sail from South Florida with new passengers. Princess Cruise Lines says 92 passengers and 13 crew members aboard the Ruby Princess were affected by Norovirus. It causes vomiting, diarrhea and stomach pain. The ship returned to Port Everglades Sunday and is getting ready to sail Sunday after being disinfected. A second ship, Crown Princess, had reported passengers and crew members getting sick, but spokeswoman Julie Benson says the cause of the illnesses is not yet known. The ship returned to Port Everglades Saturday and returned to sea later that night. All cabins and public areas on the ships were disinfected, which briefly delayed their next departures. Both ships were carrying just over 3,000 passengers each.
