Polio is an infection caused by a virus. Thanks to vaccination campaigns worldwide, the disease is almost eradicated, except in a few countries.
To avoid the virus spreading from these countries, the World Health Organisation (WHO) has imposed some extra preventive measures.
- All travelers (of all ages) staying more than 4 weeks in countries where WPV1, cVDPV1 or cVPDP3 exist, with risk of international diffusion, have to be vaccinated against polio. This vaccine has to be administered at least 4 weeks and maximum 12 months before leaving one of these countries. Administration of the vaccine has to be documented in the International Certificate of Vaccination or Prophylaxis (on the pages 4 and 5 reserved for mandatory vaccines):
- Afghanistan (WPV1)
- Madagascar (cVDPV1)
- Malawi (WPV1)
- Pakistan (WPV1)
