Cruise Norovirus Outbreaks Rare Despite Headlines

Cruise travelers worried about norovirus outbreaks this season can breathe easier, as infections aboard ships remain far less common than often portrayed. According to a recent report from Cruise Radio, cruise ships are not the viral hotspots they’re frequently made out to be—and are in fact under stricter health scrutiny than most land-based settings.

Norovirus, a highly contagious virus causing vomiting and diarrhea, spreads through contaminated food, surfaces or close contact. While it garners widespread attention when cases occur on cruise ships, the actual numbers tell a different story. In Canada alone, around one million cases of norovirus are reported each year, mostly in schools, hospitals and care facilities—not at sea.

By contrast, only 16 outbreaks were reported across the entire cruise industry in 2024, affecting fewer than 900 individuals. As of mid-2025, just 17 outbreaks have been confirmed, according to the U.S. Centers for Disease Control and Prevention (CDC). Cruise lines are required to report outbreaks when 2% of passengers and crew, or 3% of guests alone, become ill—a level of transparency not mandated at resorts or airports.

Cruise ships are also rigorously inspected. In Canada, the Public Health Agency’s Travelling Public Program conducts unannounced sanitation checks at seven ports, requiring a minimum score of 86 out of 100.

Experts recommend simple preventative steps to stay healthy onboard: wash hands regularly, use hand sanitizer at buffets, avoid touching shared surfaces and report symptoms early. Most cruise lines waive medical fees in such cases to help contain potential outbreaks.
