Polio Circulation Alert for International Travelers
The CDC has issued a Level 2 travel health alert regarding circulating poliovirus in multiple countries across Africa, Asia, the Middle East, and Europe. Travelers planning international trips should verify their polio vaccination status before departure.
Affected Regions
Poliovirus circulation has been documented in over 30 countries, including:
Africa: Afghanistan, Algeria, Benin, Cameroon, Chad, Côte d'Ivoire, Democratic Republic of the Congo, Niger, Nigeria, Somalia, Sudan, Guinea, Angola, Senegal, Ethiopia, South Sudan, Djibouti, Burkina Faso, Central African Republic, Tanzania, and Namibia
Middle East/Asia: Pakistan, Yemen, Israel, West Bank and Gaza, Laos, and Papua New Guinea
Europe: Germany, Poland, United Kingdom (England, Scotland, Wales, Northern Ireland)
Key Recommendations
- Verify vaccination status: Ensure you are up to date on polio immunization before international travel
- Consult healthcare providers: Review your vaccination records at least 4-6 weeks before departure
- Documentation: Some countries may require proof of polio vaccination for entry
- Post-travel monitoring: Be aware of symptoms (fever, muscle weakness, paralysis) and seek medical attention if they develop
Background
Polio remains a public health concern in regions with limited vaccination coverage. While polio has been nearly eradicated globally, sporadic cases and localized outbreaks continue in areas with low immunization rates or compromised disease surveillance systems.
