Norovirus outbreak hits Ruby Princess sailing from San Francisco
A norovirus outbreak sickened 125 people aboard Princess Cruises’ Ruby Princess during a 20-day round-trip cruise sailing from San Francisco to Alaska and Canada. Federal health officials said 102 passengers and 23 crew reported illness, with symptoms including vomiting and diarrhea, prompting enhanced cleaning, isolation of sick individuals, and shipwide disinfection before the next sailing.
Key Takeaways
- Scale: 125 total cases were reported (102 passengers, 23 crew) on Ruby Princess.
- Route: The voyage ran round-trip from San Francisco to Alaska and Canada on a 20-day itinerary.
- Response: The crew increased sanitation, isolated ill people, and planned thorough cleaning before the next departure.
- Why it matters: Norovirus spreads easily in close quarters, and risks can be higher for vulnerable passengers.
What happened on the cruise from San Francisco?
More than 120 passengers and crew members fell ill during a Princess Cruises voyage that began in San Francisco, according to federal health officials cited by WSMV. The ship, Ruby Princess, was on a 20-day round-trip journey to Canada and Alaska when the illnesses were reported.
WSMV reported that 102 passengers and 23 crew members were stricken, and officials identified the stomach virus as norovirus. The report noted that not everyone was sick at the same time, and not all infected people were necessarily ill when the ship arrived or left port.
How many people got sick, and what were the symptoms?
The total case count reported was 125 people: 102 passengers and 23 crew, per WSMV. Symptoms associated with the outbreak included vomiting and diarrhea, which are commonly reported in gastrointestinal illness outbreaks.
Princess Cruises said in a statement that the crew responded promptly and implemented “enhanced sanitation protocols across the ship,” WSMV reported. The company also said the ship would be thoroughly cleaned and disinfected before departing on its next trip.
Why is norovirus such a big deal on cruise ships?
Norovirus is highly contagious and can spread quickly in crowded conditions, WSMV reported. While the illness is often short-lived for many people, the same report warned it can be dangerous for people with underlying health conditions, young children, and adults 65 and older.
That risk profile matters for cruising specifically because ships concentrate thousands of people in shared dining, recreation, and lodging spaces for days at a time. Even a “limited number” of cases can raise concerns about onboard transmission and whether enhanced sanitation measures are enough to prevent further spread.
What did the cruise line do next, and what should travelers watch for?
Princess Cruises said it took immediate steps to respond, including enhanced sanitation, and that the ship would undergo thorough cleaning and disinfection before its next departure, according to WSMV. Yahoo’s report framed the event as another reminder that cruise outbreaks can draw heightened scrutiny when cases accumulate over a voyage.
If you’re cruising soon, pay attention to any health advisories shared by the line during boarding and follow onboard guidance if you feel sick.
