Polio

What is Polio and How does it Spread?

Polio is a potentially deadly, life-altering disease caused by a virus that affects the nervous system and attacks the brain and spinal cord, often making the patient paralyzed. Mainly spread by person-to-person contact by eating raw or undercooked food or drinking water or other drinks that are contaminated with the faeces of an infected person.

What is Polio Vaccine and Why should Travellers get the vaccine?

The Polio vaccination protects individuals from the Polio virus. There are two variants in circulation: injectable and oral. Oral vaccination is used throughout most of the developing world. Canada uses an injectable polio vaccine to prevent any accidental outbreaks.

Who Should get Polio Vaccine?

All children should receive the Polio vaccine. They should receive one dose at two months, four months, six to 18 months and four to six-years-old. Travellers going to certain parts of Africa and Asia may be at risk of polio. A one-time adult Polio vaccine booster dose is recommended for previously vaccinated travellers to certain countries. Even though some people are vaccinated in their childhood, they should still need to get a booster dose. People who handle specimens of Poliovirus, health care workers who may come in contact with infected people should get vaccinated.
