Multiple cruise ships have experienced significant gastrointestinal illness outbreaks this year, raising concerns among travelers. The most recent incident occurred aboard the Rotterdam, operated by Holland America Line. Over a two-week voyage that began in Fort Lauderdale, Florida, at least 116 individuals—comprising both passengers and crew members—fell ill. Health authorities attribute the outbreak to norovirus, a highly contagious virus known for its rapid spread in confined spaces.

Cruise environments are particularly vulnerable to such health issues due to their communal dining areas and close living quarters. This year has seen an alarming increase in reported cases compared to previous years. Already, seven outbreaks have been documented in 2025, with two occurring just in February. Historically, there were only three outbreaks in the same period last year. The Radiance of the Seas, managed by Royal Caribbean, also suffered from an outbreak affecting 168 people before docking on February 8. While the exact cause remains undetermined, experts suspect norovirus due to its prevalence in similar situations.

Despite these challenges, it's important to remember that cruise-related norovirus cases represent less than 1% of all U.S. occurrences. The broader surge in norovirus incidents across the country suggests that the issue extends beyond the maritime sector. To ensure a safer travel experience, the Centers for Disease Control and Prevention (CDC) advises frequent handwashing, avoiding areas where others show signs of illness, and promptly reporting suspected cases to ship staff. By adhering to these precautions, travelers can help mitigate the risks associated with gastrointestinal illnesses during their voyages.
