Holland America Line’s Veendam was hit with a possible norovirus outbreak on its December 20-27 cruise, ending in San Diego on Sunday. Fifty-seven of 1,429 passengers or almost 4 percent of passengers were reported ill with vomiting and diarrhea as the primary symptoms, according to the U.S. Centers for Disease Control, which investigates illnesses on cruise ships.
Ten of 588 crew members, or 1.7 percent of the crew, also were ill during the cruise. While the CDC lists the causative agent as “unknown,” the reported symptoms mimic that of norovirus, which occurs on both land and sea in places where large numbers of people gather.
