Poliomyelitis

Symptoms

Initial symptoms are those of a influenza-like illness (fever, headache, joint and muscle pain, vomiting, among other things) and can last up to 10 days. Its most serious forms may cause respiratory paralysis leading to death. Post-polio syndrome presents a new neurological weakness that may be progressive or abrupt on muscles previously affected or unaffected. It may or may not be accompanied by new health problems such as excessive fatigue, muscle pain, pain in the joints, intolerance to cold, reduced physical stamina and function, and atrophy.

Who is affected by the condition

It mainly affects children and the mechanisms for its transmission may be through faecal-oral channels or a common vehicle (contaminated water or food).

Post-polio syndrome affects patients who have had poliomyelitis for 20 years or more.

Diagnosis

Diagnosis is given clinically, supplemented with laboratory and electromyographic (EMG) tests.

Standard treatment

Symptomatic treatment with analgaesics, a ventilator where necessary, gentle exercise and possibility of orthopaedic devices to prevent deformities or to enable function.

Standard tests

In acute diagnoses, studying secretions, stools and cerebrospinal fluid. EMG in acute and later stages for diagnosing post-polio syndrome.

Prevention

Poliomyelitis has no cure but it can be prevent by vaccination.
