Data from the U.S. Centers for Disease Control and Prevention (CDC) show that incidence of a common stomach illness is on the rise on cruise ships.
In an update posted several days ago, the federal agency is now listing 13 outbreaks of norovirus on cruise ships this year, which is the highest number of outbreaks recorded on cruises since 2012. The most recent reported norovirus outbreak was on June 20 on a Viking Cruises ship in which about 120 passengers and crew members reported being ill out of about 1,200 people who were on board.
