Polio travel advisory: what travelers should know before international trips
The CDC has updated its travel advisory, highlighting about 30 polio-circulating countries (including the UK, Germany and Pakistan) and urging travelers to ensure timely polio vaccination. Polio remains a global risk even though the U.S. has been polio-free since 1979; vaccines (like IPV) provide long-term protection, so travelers should verify their vaccination status and consult CDC country notices before trips.
