Cruise Ship Stomach Illnesses Reach 12-Year High in 2024

CDC data reveals a sharp rise in norovirus outbreaks on cruise ships, with December seeing five major incidents affecting nearly 900 passengers and crew.

The CDC reported 16 gastrointestinal illness outbreaks on cruise ships in 2024, the highest number since 2012, with most caused by norovirus.
December 2024 alone saw five outbreaks, including a significant one on the Queen Mary 2, where nearly 13% of passengers fell ill.
Norovirus, known for its high contagion rate, is resistant to hand sanitizers and spreads easily in crowded, enclosed environments like cruise ships.
The rise in cases parallels a nationwide surge in norovirus activity, with outbreaks increasing by 36% compared to the same period last year.
Health officials recommend thorough handwashing, surface disinfection, and isolation for 48 hours after symptoms stop to prevent further spread.
