What is Post-polio?
Post-polio syndrome (PPS) is a condition that can affect polio survivors decades after they recover from their initial poliovirus infection. Unlike poliovirus, PPS is not contagious.
Which body part is affected by polio?
Polio is a viral disease which may affect the spinal cord causing muscle weakness and paralysis. The polio virus enters the body through the mouth, usually from hands contaminated with the stool of an infected person. Polio is more common in infants and young children and occurs under conditions of poor hygiene.
How many polio survivors are still alive?
The World Health Organization estimates that 10 to 20 million polio survivors are alive worldwide, and some estimates suggest that 4 to 8 million of them may get PPS.
Can polio affect adults?
Today, despite a worldwide effort to wipe out polio, poliovirus continues to affect children and adults in parts of Asia and Africa.
Is polio a DNA virus?
Poliovirus is composed of an RNA genome and a protein capsid. The genome is a single-stranded positive-sense RNA (+ssRNA) genome that is about 7500 nucleotides long….

Does polio affect memory?
There have been consistent reports of cognitive deficits (83) in PPS including word finding difficulties (84), poor concentration, limited attention, memory impairment (85), and mood disturbances (86). The non-motor aspects of PPS are often under evaluated despite their considerable quality of life implications (87).
Does polio affect brain?
The polio virus attacks specific neurons in the brain stem and spinal cord. Surviving cells sprout new nerve-end terminals and connect with other muscle fibers. These new connections may result in recovery of movement and gradual gain in power in the affected limbs.
Can a baby be born with polio?
In spite of this the incidence of polio virus infections causing disease in the fetus or in the new- born child is small [l]. A number of cases reported, however, have been strongly sug- gestive of an intra-uterine infection with polio virus.
Can polio affect you later in life?
Post-polio syndrome is rarely life-threatening, but severe muscle weakness can lead to complications: Falls. Weakness in your leg muscles makes it easier for you to lose your balance and fall. You then might break a bone, such as a hip, leading to other complications.
Who was a famous person with polio?

Can polio come back in old age?
Post-polio syndrome is a group of potentially disabling signs and symptoms that appear decades after the initial polio illness. These signs and symptoms usually appear between 30 to 40 years after having polio. Infection from the polio virus once caused paralysis and death.
Can you recover from polio?
People who have milder polio symptoms usually make a full recovery within 1–2 weeks. People whose symptoms are more severe can be weak or paralyzed for life, and some may die. After recovery, a few people might develop “post-polio syndrome” as long as 30–40 years after their initial illness.
What is the shape of polio?
The poliovirus capsid contains 60 copies each of the four viral polypeptides VP1, VP2, VP3, and VP4. The arrangement of proteins in the capsid creates icosahedral symmetry. The virion surface is covered with star-shaped mesas at its fivefold axes surrounded by deep canyons and three-bladed propellers.
Can a woman with polio get pregnant?
Conclusion: Pregnancy in female survivors of polio is associated with an increased risk for complications during pregnancy and delivery, as well as an adverse perinatal outcome. Awareness towards risk factors should improve pre-natal care and possibly prevent complications.
Does polio affect hands?
The infected person may or may not have any symptoms, but can still spread the virus. Symptoms vary from mild flu-like symptoms to life-threatening paralysis. In less than 1% of cases, polio causes permanent paralysis of the arms, legs or breathing muscles.

Between 2 and 10 out of 100 people who have paralysis from poliovirus infection die, because the virus affects the muscles that help them breathe. Even children who seem to fully recover can develop new muscle pain, weakness, or paralysis as adults, 15 to 40 years later.
