How does polio affect the body?
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..
Where did polio originally come from?
Like a horror movie, throughout the first half of the 20th century, the polio virus arrived each summer, striking without warning. No one knew how polio was transmitted or what caused it. There were wild theories that the virus spread from imported bananas or stray cats. There was no known cure or vaccine.
What body systems are affected by polio?
Polio affects the body by attacking your central nervous system. It infects the spinal cord, brain and surrounding tissues. Your symptoms vary depending on which area of the spinal cord and brain it attacks. If you are affected by a lesser strain of poliovirus, you may experience minor symptoms that mirror the flu.
How is polio treated today?
Once the virus that causes polio has infected a person, there is no treatment that will cure polio. Early diagnosis and supportive treatments such as bed rest, pain control, good nutrition, and physical therapy to prevent deformities from occurring over time can help reduce the long-term symptoms due to muscle loss.
How long is a person with polio contagious?
How long is a person with polio contagious? Patients infected with the polio virus can pass the virus on for 7–10 days before the onset of disease. In addition, they can continue to shed the virus in their stool for 3–6 weeks.
What is polio how it is caused?
Polio, or poliomyelitis, is a disabling and life-threatening disease caused by the poliovirus. The virus spreads from person to person and can infect a person’s spinal cord, causing paralysis (can’t move parts of the body).
Can polio be cured?
The poliovirus can easily be imported into a polio-free country and can spread rapidly amongst unimmunized populations. Failure to eradicate polio could result in as many as 200 000 new cases every year, within 10 years, all over the world. There is no cure for polio, it can only be prevented.
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.
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).
Does polio affect the heart?
Polio patients have a high prevalence of risk factors for coronary heart disease as well as cardiac-related disease. These factors include dyslipidemia. Although our present findings are similar to those from previous studies, we found a higher percentage of women with dyslipidemia.
What stopped polio?
Several key strategies have been outlined for stopping polio transmission: High infant immunization coverage with four doses of oral polio vaccine (OPV) in the first year of life in developing and endemic countries, and routine immunization with OPV and/or IPV elsewhere.
How long does it take for polio symptoms to appear?
Polio symptoms generally appear between three and 21 days after infection. However, many people infected with poliovirus have no symptoms and may not even know they are affected.
