Many people think that poliovirus always causes polio, which can cause
lifelong paralysis. However, some people may get infected with
poliovirus and not develop any symptoms, while others may have minor

-Benefits of polio vaccine-

· Saves lives.
· Protects young children from serious disease and lifelong disability.

Side effects of the polio vaccine-

· The most common side effects are usually mild and include redness and
pain from the shot.

*What is polio?*

Polio (or poliomyelitis) is a disease caused by poliovirus. It can cause
lifelong paralysis (can’t move parts of the body), and it can be deadly.
But, the polio vaccine can protect against polio.

*What are the symptoms of *poliovirus infection*?*

Most people who get infected with poliovirus do not have any symptoms.

A small number of people (4 to 8 people out of 100) will have flu-like
symptoms. These symptoms usually last 2 to 5 days then go away on their

In rare cases, poliovirus infection can

*Poliomyelitis* /poʊlioʊmaɪəlaɪtɪs/, often called *polio*
or *infantile paralysis*, is an acute, viral, infectious disease spread
from person to person, primarily via the fecal-oral route.^[1] The term
derives from the Greek /poliós/ (πολιός), meaning
"grey", /myelós/ (µυελός “marrow”),
referring to the grey matter of the spinal cord, and the suffix /-itis/,
which denotes inflammation.,^[2] i.e., inflammation of the spinal
cord’s grey matter, although a severe infection can extend into the
brainstem and even higher structures, resulting in polio/encephal/itis,
producing apnea that requires mechanical assistance such as an iron lung.

Although approximately 90% of polio infections cause no symptoms at all,
affected individuals can exhibit a range of symptoms if the virus enters
the blood stream.^[3] In about 1% of cases, the virus enters the central
nervous system, preferentially infecting and destroying motor neurons,
leading to muscle weakness and acute flaccid paralysis. Different types of
paralysis may occur, depending on the nerves involved. Spinal polio is the
most common form, characterized by asymmetric paralysis that most often
involves the legs. Bulbar polio leads to weakness of muscles innervated by
cranial nerves. Bulbospinal polio is a combination of bulbar and spinal

Poliomyelitis was first recognized as a distinct condition by Jakob Heine
in 1840.^[5] Its causative agent, poliovirus, was identified in 1908 by
Karl Landsteiner.^[5] Although
