Polio is a contagious infection caused by the poliovirus. The virus is transmitted person-to-person or through contaminated food and water. Symptoms include fever, fatigue, nausea and aching muscles, with paralysis occurring rarely. As a result of vaccination, Canada has been polio free since 1994. There are only a few countries in the world where the disease remains and work is underway to globally eradicate polio. Infants and children in Ontario are immunized for protection against polio.

To obtain or inquire about an immunization record, or for general immunization information, please contact your local public health unit.
