The poliovirus is still prevalent, therefore the Centers for Disease Control and Prevention advises visitors to take extra measures while visiting countries including Canada, the United Kingdom, Madagascar, and Indonesia.
In a recently revised advice, the government listed 30 nations where visitors are at risk for the disease and issued a Level 2 notice encouraging them to "practice enhanced precautions."
The virus still survives in certain areas where polio is still widespread, and it has been found in other locations across the world. However, it was eliminated in the western hemisphere in 1994.
According to the CDC, there is still active poliovirus in the following places:
- Afghanistan
- Algeria
- Benin
- Botswana
- Burundi
- Cameroon
- Canada
- Central African Republic
- Chad
- Côte d'Ivoire
- Democratic Republic of the Congo
- Djibouti
- Egypt (health care facilities, refugee camps and humanitarian aid settings only)
- Ghana
- Indonesia
- Israel
- Madagascar
- Malawi
- Mali
- Mozambique
- Niger
- Nigeria
- Pakistan
- Republic of the Congo
- Somalia
- Sudan
- Togo
- United Kingdom
- Yemen
- Zambia
The organization advises adults who have received all of their recommended doses of the inactivated polio vaccine to receive a single booster dose if they are traveling to these areas with children. When leaving the country, you might need to present immunization documentation.
