Polio

After entering the body, the poliovirus multiplies in the throat and intestines before potentially spreading into the bloodstream and nervous system. In most cases, infection is asymptomatic or causes only mild flu-like symptoms. However, in a small proportion of cases, the virus attacks nerve cells in the spinal cord, leading to muscle weakness or paralysis.

The symptoms of polio vary depending on severity. Mild cases may include fever, sore throat, headache, nausea, and fatigue. In more severe cases, patients may experience intense muscle pain, stiffness, and sudden onset of flaccid paralysis, often affecting the legs. Respiratory muscles can also be involved, which may become life-threatening without medical support.

There is no cure for polio once infection has occurred, so treatment focuses on supportive care. This may include pain management, physical therapy, and respiratory assistance if breathing muscles are affected. Rehabilitation plays a key role in helping individuals regain function or adapt to long-term disability.

A major long-term complication of polio is post-polio syndrome, which can occur years or decades after initial infection. This condition is characterized by new muscle weakness, fatigue, and joint pain in individuals who previously recovered. It is believed to result from gradual deterioration of surviving nerve cells that compensated for earlier damage.

Diagnosis of polio is based on clinical presentation and confirmed through laboratory testing of throat swabs, stool samples, or cerebrospinal fluid. Due to global eradication efforts, cases are now rare in most parts of the world, but surveillance remains important to detect and prevent outbreaks.

The most effective prevention strategy is vaccination. The inactivated polio vaccine (IPV) and the oral polio vaccine (OPV) have been instrumental in dramatically reducing global cases. Widespread immunization campaigns have brought the world close to eradication, though continued vaccination is necessary to prevent resurgence.

Polio is a preventable but potentially disabling disease. Thanks to global vaccination efforts, cases have declined dramatically, but maintaining high immunization coverage and strong public health systems remains essential to achieving and sustaining eradication worldwide.
