The Princess Cruise line Ruby Princess has reported a stomach illness outbreak on its latest cruise. The ship had voyage dates of March 3 to March 10, 2013. Symptoms include vomiting and diarrhea. There is no known cause, although the cause of most outbreaks on cruise ships is norovirus. Symptoms of that highly contagious virus include nausea, diarrhea, vomiting, abdominal pain, along with possible headache and low grade fever.

The outbreak was communicated to the Vessel Sanitation Program of the Centers for Disease Control and Prevention on March 10, 2013, so no on board response to the outbreak was conducted.
