More than 100 passengers and 13 crew members aboard the Caribbean Princess fell ill with norovirus, the CDC reports. Isolated travelers and aggressive sanitation followed as the ship cruises north of the Dominican Republic.

Princess Cruises confirmed 102 passengers and 13 crew showed mild gastrointestinal symptoms during the April 28 voyage. The line disinfected every area and added extra cleaning protocols before the vessel’s next journey.

The outbreak adds to a pattern: in March, nearly 200 passengers aboard the Star Princess suffered similar symptoms, and last year 2,200 people were sickened across 18 cruise‑ship outbreaks nationwide.

Investors will watch how the company manages the incident and potential reputational costs. The company’s decisive response and comprehensive cleaning may mitigate long‑term brand damage, but the incident underscores the fragility of cruise‑industry safety protocols.
