In the United States, we don’t think much about polio because it has generally been eradicated from our country. Great progress has been made in eradicating it from the rest of the world, but there are some countries that still have an issue with polio. In May 2017, The World Health Organization updated its polio vaccine recommendations, and the CDC issued guidance for travel to and from countries affected by these new polio vaccine requirements.

Travelers to Afghanistan, Nigeria, or Pakistan may need proof of polio vaccination prior to departing the country. These recommendations will be updated periodically as more surveillance is conducted. But travelers to these countries should seek council from a travel health specialist to make sure they are up-to-date with polio vaccine recommendations and documentation requirements.
