CDC Sounds Global Polio Alert as Cruise Destinations Hit List

The CDC has issued a Level 2 Travel Health Notice for poliovirus after detections in 32 countries across Africa, Europe, Asia and the Middle East. The advisory highlights cruise hubs such as Spain, the UK, Germany and Indonesia and urges travelers, including cruise passengers, to be up to date on polio vaccination and consider a lifetime booster if they completed the routine series. The warning is not a cancellation call but a reminder to review vaccination status before international voyages, especially itineraries that visit multiple countries.
