Overview
- The CDC logged 95 passengers and 6 crew with diarrhea or vomiting out of 2,007 guests and 640 staff on the AIDAdiva.
- AIDA Cruises reported the outbreak on Nov. 30 during the Nov. 10–Dec. 16 voyage and says reported cases are declining.
- The operator isolated ill individuals, intensified cleaning and disinfection, collected stool samples, and consulted the CDC’s Vessel Sanitation Program.
- This incident is the 21st cruise-ship gastrointestinal outbreak reported in 2025, topping counts from 2024 and 2023 as monitoring continues.
- Norovirus spreads through contaminated food, water, surfaces and aerosolized vomit, and thorough handwashing with soap and water is the most effective prevention.
