The only polio around is vaccine derived polio.
“In April 1955 more than 200 000 children in five Western and mid-Western USA states received a polio vaccine in which the process of inactivating the live virus proved to be defective. Within days there were reports of paralysis and within a month the first mass vaccination programme against polio had to be abandoned. Subsequent investigations revealed that the vaccine, manufactured by the California-based family firm of Cutter Laboratories, had caused 40 000 cases of polio, leaving 200 children with varying degrees of paralysis and killing 10.” The more you know...... Polio is a nickname for poliomyelitis, which means inflammation of the grey matter of the spinal cord. If you get a lesion on your spinal cord, that part of your body may develop paralysis. This disease nearly always occurred in children, which is why it was called infantile paralysis for decades. Polio was basically non-existent before the 1800’s. You don’t really see it in medical literature until the 1890’s when it began to appear in epidemic form. As it turns out, the paralysis of poliomyelitis can be caused by many different things. Several viruses can cause it, as can several different bacterial infections. Surprisingly pesticides could also cause it. Studies were conducted in the late 1800’s with a popular pesticide called Paris Green. They purposely fed animals too much pesticide and it paralysed them in their “hind quarters” just like what was happening with children. Scientists did autopsies on the animals, found lesions in their spinal cords, and pronounced they had died from polio-from pesticide poisoning. The pesticide contained a metal called arsenic, and may explain why parents originally referred to polio as teething paralysis. A popular medical treatment at the time was “teething powders”, a concoction given to infants who were teething. They contained massive amounts of similar metal - mercury. Teething powders became popular in the early 1800’s and appeared about the same time you started seeing isolated cases of polio. Coincidence?
