Overview
- Since the voyage began, 95 passengers and 6 crew have been counted as cases, representing 4.8% of guests and 0.9% of crew among 2,647 people on board.
- The tally is cumulative over the trip rather than simultaneous illnesses, and the event was reported to the CDC on November 30 after recent U.S. port calls triggered notification rules.
- Under CDC guidance, the ship has stepped up cleaning and disinfection, collected stool samples for testing, and isolated symptomatic passengers and crew.
- CDC officials are monitoring compliance remotely as the ship transits near the Panama Canal toward Pacific ports, with a scheduled return to Hamburg on March 23, 2026.
- Norovirus is highly contagious and a common cause of acute gastroenteritis in close environments such as cruise ships, and there is no licensed vaccine.
