What is it? It is also known as «Polio» or «Infantile paralysis». Its name came from the greek words «poliós» which means grey, «myelós» which means spinal cord, and «itis» which means inflammation. It is a viral infectious disease, transmitted by fecal-oral route. It mainly affects the spinal cord, but can also affects the brainstream, causing «Polioencephalitis». 1% of polio cases afect the Central Nervous System (muscle weakness and flaccid paralysis).
Types of paralysis Different types of paralysis can occur depending on the part of the body they affect. Spinal polio: causes asimetric paralysis and mainly affects the legs. Bulbar polio: leads to weakness of the nerves controlled by cranial nerves. Bulbospinal polio: combination of bulbar and spinal paralysis.
