Children or young people with fever, asymmetric flaccid limb paralysis or medullary paralysis without sensory impairment are often almost all poliomyelitis, but it may also be caused by Coxsackievirus, some echoviruses and enterovirus 71. Spinal cord damage is mainly in the lumbar and cervical vertebrae. The brainstem or brain may also be invaded. Neurons are destroyed and paralysis cannot be restored; if it is squeezed by congestion, edema, it can be restored to varying degrees or completely. The characteristics of paralysis are flaccidity, bilateral asymmetry, not distributed according to the distribution area of ​​peripheral nerve trunks, and not accompanied by sensory impairment and imbalance. The onset can be slow or acute, and the main manifestation is fever, generally between 38℃ and 39℃, accompanied by sweating, coughing, runny nose and other upper respiratory tract inflammation phenomena. After 2 to 3 days, the body temperature can return to normal. After 1 to 6 days, the fever reappears, forming two fever peaks with the first fever, that is, "biphasic fever". This is a special fever type of poliomyelitis fever, which can be distinguished from colds. Subsequently, typical symptoms such as muscle pain, hyperesthesia, stiffness of the neck and back, and even limb paralysis gradually appear.
