Polio: Advice for travellers

Original publication date: March 7, 2018

Updated: April 22, 2025

Current situation

The World Health Organization (WHO) declared the international spread of poliovirus a public health emergency of international concern (PHEIC) in May 2014 and issued temporary recommendations to polio-affected countries to prevent or reduce further spread of the disease. The polio PHEIC, and the temporary recommendations, are reviewed every 3 months. 

These temporary recommendations may impact your travel.

Some countries may have more than one type of circulating poliovirus. The following destinations have circulating wild poliovirus type 1 (WPV1) or circulating vaccine derived poliovirus (cVDPV) types 1 or 3:

• Afghanistan
• Democratic Republic of the Congo
• French Guiana
• Guinea
• Mozambique
• Pakistan

Travellers who are visiting these countries for longer than 4 weeks may be required to receive a dose of polio vaccine 1 to 12 months before they leave this destination and return to Canada or travel on to another international destination. This may be required even if you have previously received all the recommended polio vaccine doses as part of the routine vaccine schedule in Canada. 

Make sure that the polio vaccination is documented on the International Certificate of Vaccination or Prophylaxis.

The following destinations have reported cVDPV type 2, with or without evidence of local transmission:

• Algeria
• Angola
• Benin
• Cameroon
• Chad
• Côte d'Ivoire
• Democratic Republic of the Congo
• Djibouti
• Egypt
• Equatorial Guinea
• Ethiopia
• Finland
• Gambia
• Germany
• Ghana
• Guinea
• Indonesia
• Israel, the West Bank, and the Gaza Strip
• Kenya
• Liberi
• Mali
• Mozambique
• Niger
• Nigeria
• Poland
• Senegal
• Sierra Leone
• Somalia
• South Sudan
• Spain
• Sudan
• Uganda
• United Kingdom
• Yemen
• Zimbabwe

A country with local transmission of cVDPV2 may encourage travellers visiting for longer than 4 weeks to receive a dose of the polio vaccine 1 to 12 months prior to departing that country. This is to prevent spread to other countries.

About polio

Polio (poliomyelitis) is a highly infectious disease and can spread easily from person to person through contaminated food and water. It enters the body through your mouth, mainly from food or water that is contaminated with feces.
Most people infected with the poliovirus don’t have any symptoms. Those who get symptoms may at first experience:

• fever
• sore throat
• headache
• Abdominal pain
• nausea and vomiting
• tiredness
• loss of appetite
• aching muscles
• stiff neck or back

Typically, symptoms last between 2 and 10 days and go away on their own.

In rare cases, poliovirus infection can damage a person’s nervous system, which includes the brain and spinal cord. This can result in weakness or paralysis (the loss of the ability to move all or part of your body). Nerve and muscle damage caused by polio can be permanent.

Recommendations

Talk to a healthcare provider or visit a travel health clinic preferably about 6 weeks before your trip to get personalized health advice. Even if you’re short on time, it’s still worthwhile to make an appointment.

Discuss with the healthcare provider:

• which pre-travel vaccines or medications may be right for you.
• whether your routine vaccinations, like polio, are up-to-date. Many require a booster as an adult.
• the medications you’re currently taking or planning to bring with you.

Polio vaccination recommendations:

Get vaccinated for polio if you:

• haven’t received all the recommended doses of polio vaccine according to your provincial/territorial vaccination schedule
• don't know your vaccination history

Infants and children under 18 years of age:

• Polio is part of the routine childhood immunization schedule for children in Canada. 
• Make sure your child has received all recommended doses before travelling.

Adults (18 years and older):

• Get a booster dose if you've received all the recommended doses of polio vaccine according to provincial/territorial vaccination schedule and haven't received a polio booster dose since your 18th birthday.
• Get your remaining scheduled doses before leaving if you haven't completed your polio vaccine series.
• Get fully vaccinated against polio before leaving if you haven't received any polio vaccines.

Proof of vaccination

• Temporary polio vaccine recommendations have been issued by the WHO for some polio-affected countries.
  • Depending on the type of circulating poliovirus,these countries may require long-term travellers (visiting longer than 4 weeks) to show proof of polio vaccination when leaving the country.
  • To meet this requirement, long-term travellers to polio-affected countries should receive the polio vaccine between 4 weeks and 12 months before their date of departure from the country.
• Make sure that the polio vaccination is documented on the International Certificate of Vaccination or Prophylaxis. This is the only document accepted as proof of vaccination. In Canada, they are provided at yellow fever vaccination centres.
• Carry the certificate as proof of vaccination.
