Identification and Definition
History of Polio
Signs and Symptoms of Polio
Most people who get infected with poliovirus (about 72 out of 100) will not have any visible symptoms.
About 1 out of 4 people with poliovirus infection will have flu-like symptoms that may include:
- Sore throat
- Stomach pain
These symptoms usually last 2 to 5 days then go away on their own.
A smaller proportion of people with poliovirus infection will develop other more serious symptoms that affect the brain and spinal cord:
- Paresthesia (feeling of pins and needles in the legs)
- Meningitis (infection of the covering of the spinal cord and/or brain) occurs in about 1 out of 25 people with poliovirus infection
- Paralysis (can’t move parts of the body) or weakness in the arms, legs, or both, occurs in about 1 out of 200 people with poliovirus infection
Transmission of Polio
Complications of Polio
Adults who seemed to have recovered fully from polio as children can develop muscle pain, weakness, or paralysis decades later. This is known as post-polio syndrome.
Additionally, polio can result in death from paralysis of muscles that help the person breathe.
Recommended Control Measures for Polio
Vaccinations for this disease should be mandatory everywhere in order to protect people from the spread of polio once again. It is important to ensure that this disease remains eradicated and to try to eradicate it in the two countries where the disease is still an issue.
