U.S.(Washington Insider Magazine) – Norovirus cases are rising across the U.S. and cruise ships, with nearly 900 passengers infected in December alone, according to the CDC.
The RMS Queen Mary 2 was among several cruise lines impacted, with 13% of passengers and 5% of crew experiencing symptoms like vomiting and diarrhea.
Norovirus Cases Exceed Pre-Pandemic Levels
The CDC reports 91 suspected or confirmed outbreaks in early December—higher than previous winter seasons since 2012.
In 2024, there were 16 cruise ship outbreaks linked to norovirus, salmonella, and E. coli, marking the highest number in 12 years.
Why Is Norovirus Spreading?
Norovirus is a highly contagious virus spread through contaminated food, water, surfaces, and person-to-person contact. Most outbreaks occur in hospitals, restaurants, and long-term care facilities.
Who’s Most at Risk?
- Young children and older adults face the highest risk of severe dehydration.
- The virus lingers on surfaces for weeks, increasing the risk of continued infections.
Cruise Lines Implement Strict Sanitation Measures
Following multiple outbreaks, cruise operators, including Cunard and Holland America, have intensified cleaning, sanitization, and isolation protocols to prevent further spread.
CDC’s Prevention Guidelines
To reduce infections, the CDC recommends:
✅ Frequent handwashing with soap
✅ Sanitizing surfaces regularly
✅ Avoiding shared utensils and food
With norovirus cases continuing to rise, health officials stress vigilance and hygiene as crucial steps in controlling the outbreak.
