Hint: According to the World Health Organization (WHO), one in every 200 polio contaminations causes permanent paralysis, and this disease has been eradicated due to the development of a polio antibody. In 2010, the World Health Organization reported only 1,352 cases of polio worldwide. (World Health Organization)

Complete answer:
Poliomyelitis is the full name for the illness Polio. It induces muscle shortening in very rare situations, resulting in inability to move or loss of motion. Poliovirus may be transmitted from person to person, through food or water contaminated with human defecation, and in rare cases, through infected saliva. Polio can be classified into three types:
1) Subclinical: This type of polio has no side effects because it does not affect the focal sensory system – the mind and spinal cord. Normally, 95 percent of polio cases identified are subclinical.
2) Non-Paralytic: This type of polio affects the focal sensory system but does not cause loss of motion.
3) Paralytic: This is the most severe and rare type of polio, causing complete or partial paralysis in the patient. There are three types of paralysed polio:
Spinal Polio – As the name implies, it affects the spine.
Bulbar polio affects the brain stem.
Bulbospinal Polio – This type of polio affects the spine and brainstem.
Poliovirus has an incubation period of 1-14 days and 7-14 days.The poliovirus belongs to the Picornaviridae family of enteroviruses. Enteroviruses are short-term residents of the gastrointestinal tract that thrive in an acidic environment. Picornaviruses are small, ether-heartless infections with an RNA genome.

Note:
Poliovirus only infects individuals. It reaches the body through the mouth and spreads through: contact with infected individual's faeces (dung). Drops from a tainted person's wheeze or hack (more uncommon).
