Can poliomyelitis be genetic?

No. Poliomyelitis occurs as a rare response to infection by one of 3 subtypes of the polio virus. These viruses commonly live in the intestinal tract and when common, 95% of those infected had no symptoms.Of those who developed the disease, the active distruction of nerve cells and eventual atrophy(shrinkage) of muscles the nerves supplied produced long term disability.
Inherited polio? Poliomyelitis is caused by infections with polio virus and certain other viruses. It is not inheritable.
