Just over 300 people have been sickened in norovirus outbreaks on three different cruise ships in December, new government data shows.

Not all cruise ships are as clean as they seem. The CDC's 2024 report highlights the ships that fell short on sanitation.

According to the 2024 report, the average score out of 151 inspections was 95.9. Twenty-three of those vessels were inspected for a second time. The nine dirtiest ships received scores between 86 and 89. Meanwhile, one ship initially received a rare low score of 62 before it was reviewed again the following month and given an 89.

The Caribbean will welcome many new cruise ships in 2025. Here’s what to expect from the most exciting new vessels in the upcoming year.
