A gastrointestinal outbreak on Oceania Marina has been reported to the CDC (Centers for Disease Control and Prevention).
69 passengers, which is 5,8% out of the 1185 guests on board, and 11 crew members (1,4% of 769), have been reported ill with nausea and vomiting during the last sailing of ms Marina - a 16-day repositioning Panama Canal cruise from Callao port, Peru to New York City, USA.
During the first five months of the year, this is the 8th GI outbreak. There were 9 gastrointestinal illness outbreaks in all of 2014. Royal Caribbean and Princess have been the leaders with the biggest number sick ships during the last two years.
After each Norovirus outbreak, there is a debate how it occurred. The cruise industry and lines' employees always blame the passengers. The CDC does not figure the causation out. The experts blame the outbreak on dirty surfaces, a cook or waiter working while ill, inadequate cleaning/air contamination or contaminated cruise water/food.
