Polio or poliomyelitis is a communicable viral disease which affects the nerves and can lead to partial or permanent paralysis. It is transmitted through stool or saliva. The global effort to eradicate polio has been very successful and from 350,000 cases in 1988 only 40 cases were reported worldwide in 2012. There is no cure for the diseases though vaccination can prevent the disease for life. India has done remarkably in eradicating polio and from 2011 no new cases were reported.
