How common is post polio syndrome?
Post-polio syndrome affects people who have had acute episodes of poliomyelitis.
It occurs 10 years or more after the original illness, and can occur as long as 40 years afterward.
According to one estimate, 25% to 50% of the 300,000 polio survivors in the United States may develop the syndrome..
What are the long term effects of polio?
Between 5 and 10% of people who develop paralytic polio will die. Physical symptoms may return 15 years or more after the first polio infection. These new symptoms are called the ‘late effects of polio’. They include new muscle weakness, joint and muscle pain and fatigue.
How long do polio survivors live?
For years, most polio survivors lived active lives, their memory of polio mainly forgotten, their health status stable. But by the late 1970s, survivors who were 20 or more years past their original diagnosis began noting new problems, including fatigue, pain, breathing or swallowing problems, and additional weakness.
Where did polio originally come from?
1894, first outbreak of polio in epidemic form in the U.S. occurs in Vermont, with 132 cases. 1908, Karl Landsteiner and Erwin Popper identify a virus as the cause of polio by transmitting the disease to a monkey.
How old is the oldest polio survivor?
Loraine Allen may be the oldest survivor of polio in the U.S. Allen is 97.
Can polio return in later life?
Post-polio syndrome refers to a cluster of potentially disabling signs and symptoms that appear decades — an average of 30 to 40 years — after the initial polio illness. Polio once resulted in paralysis and death. However, the inactivated polio vaccine greatly reduced polio’s spread.
Is polio contagious years later?
When and for how long is a person able to spread polio? Patients are most infectious from seven to ten days before and after the onset of symptoms. However, patients are potentially contagious as long as the virus is present in the throat and feces.
What does Polio do to muscles?
When it multiplies in the nervous system, the virus can destroy nerve cells (motor neurons) which activate skeletal muscles. These nerve cells cannot regenerate, and the affected muscles lose their function due to a lack of nervous enervation – a condition known as acute flaccid paralysis (AFP).
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.
Who gets post polio syndrome?
PPS happens in some people who have recovered from polio. It starts an average of 35 years after the original polio and may eventually make it hard to breathe. PPS may cause the muscles to shrink.
What really caused polio?
What causes polio? Polio is caused by the poliovirus. The virus enters the body through the mouth. It is spread through contact with the feces (stool) of an infected person or through exposure to phlegm or mucus when an infected person coughs or sneezes.
