What are the common symptoms of polio?

Polio is a relatively common disease, and most of the patients are children. Compared with other orthopedic diseases, polio has more distinct characteristics. When choosing the treatment method for polio, we must base it on the characteristics of polio. So what are the common symptoms of polio? Let's talk about it in detail below.

Experts say that polio accounts for 80 to 90 percent of clinical infections, mainly in children. The clinical manifestations are mild, and the central nervous system is not affected. Symptoms such as mild fever, malaise, headache, sore throat and vomiting appear 3 to 5 days after exposure to the pathogen, and generally recover within 24 to 72 hours. This is the characteristic of polio.

Severe cases often stabilize for a few days after the mild course, and then suddenly develop. More often, there is no prodromal symptom, especially in older children and adults. The incubation period is generally 7 to 14 days, occasionally longer. After the onset of fever, severe headache, stiff neck and back, deep muscle pain, sometimes hyperesthesia and paresthesia, urinary retention and muscle spasm in the acute phase, deep tendon reflex disappearance, may not progress further, but deep tendon reflex disappearance, asymmetric muscle weakness or paralysis may also occur, which mainly depends on the location of spinal cord or medulla oblongata damage, which is also the characteristic of polio.

Polio is also characterized by respiratory weakness, which may be caused by spinal cord involvement that paralyzes the respiratory muscles or by viral damage to the respiratory center itself. Dysphagia, nasal regurgitation, and nasal speech are early signs of medullary involvement.

The above is an introduction to the common symptoms of polio, I hope it will be helpful to everyone. Once you have polio, you must go to the hospital for treatment in time to avoid delaying the disease.
