#17 – Polio
Polio is a disease which was identified and initially recognized in the year of 1840. It is a disease that is easily spread by person to person and through contaminated food and water.
Most cases of this disease don’t exhibit symptoms unless the disease was introduced through the blood. In most cases of polio, the disease causes muscle paralysis and weakness. Polio was a very common disease in the 50s, but at the moment it has been eradicated in over 30 countries thanks to the poliovirus vaccine.
