The CDC reported that cruise ships operating under its jurisdiction experienced 16 stomach bug outbreaks this year, the highest number since 2012, affecting hundreds of passengers and crew members. Notably, the famous Cunard liner faced back-to-back outbreaks, sickening a significant portion of its guests and crew.
