The CDC randomly inspects and scores cruise ships to prevent the spread of stomach viruses. The 11 dirtiest ships this year so far scored 89 or less, including one that received 62 points. For cruise ships, scoring an 85 out of 100 on the Centers for Disease Control and Prevention's Vessel Sanitation Program review is considered a failure. The CDC has reported 10 bacterial and viral outbreaks on cruise ships since the start of 2024. The CDC checks cruise ships for details such as how frequently the pool's hair and lint strainer is disinfected.
