WTF Is Polio? 17 Facts About the Disease That We’re This Close to Eradicating

Polio has been eradicated from all but three countries around the world: Afghanistan, Pakistan, and Nigeria. That means it is 99.9% eradicated and it makes our fight to end the disease all the more pressing. That’s why we’re calling on the Canadian government to make an important contribution to help eliminate this virus once and for all.

Here are some facts you might not know about the virulent disease.

1. The first clinical description of polio was provided by Michael Underwood, a British physician, in 1789.

2. The first outbreaks appeared in Europe in the early 1800s.

3. The first known outbreak in Canada was in 1910.

4. Polio is an infectious disease caused by poliovirus. There are three strains of poliovirus. Type 2 was officially declared eradicated in September 2015 and type 3 has not been detected since November 2012. It is assumed that type 1 is the only type that remains and the cause for the few cases of polio that occur each year.

5. In 1916, New York experienced the first large epidemic in the United States, with more than 9,000 cases and 2,343 deaths. Nationwide there were 27,000 cases and 6,000 deaths.

14. In 1953, the disease reached its peak in Canada. There were almost 9,000 cases and 500 deaths. This was the worst national epidemic since the 1918 influenza pandemic.

15. There is no cure for polio, but it is preventable with a vaccine. There are two types of vaccine. IPV, which is an injected shot, was developed by Jonas Salk and declared safe in 1955. The other vaccine, OPV, is given orally in drop form and was developed by Albert Sabin and introduced in 1961.
