The norovirus stomach virus that has infected people as of late has struck a third U.S. cruise ship, sailing from New Orleans.
Royal Caribbean's "Voyager of the Sea" left a couple of hours late on Saturday because of the illnesses where 200 passengers became ill.
This virus causes vomiting and diarrhea and is easily spread in close quarters such as cruise ships.
Earlier in the weekend, two Princess Cruise Line ships sailing from Fort Lauderdale reported outbreaks of illness. They were delayed in departing while they were being disinfected.
