Polio is also a common disease among children, so as parents of babies, it is necessary to have a simple understanding of this disease so that problems can be detected and treated early in daily parenting. So, what are the symptoms of polio?
1. The typical clinical symptoms of polio can be divided into four stages, with the first being prodromal manifestations, which are the initial symptoms. Children often present with fever, and their body temperature usually returns to normal levels after 1-4 days of fever. However, they may experience recurrent fever in a few days. So when there are repeated fever symptoms, parents must be vigilant.
2. Subsequently, polio will enter a paralysis phase, during which the affected muscles will become weak, tendon reflexes will weaken, and muscle tone will also decrease. Delayed paralysis is more pronounced. Then it will enter the recovery period, where the affected muscles can gradually recover, but there are also some affected muscle tissues that are difficult to restore to normal levels.
3. Finally, there is the sequelae period. At this time, some limbs of the child may become paralyzed or muscle atrophy, and various deformities may form in the feet, such as inability to touch the ground with the toes or heels while walking, walking on the outer side of the instep, and inversion of the foot. Abnormalities in other parts of the body, such as spinal curvature, knee flexion, and upper limb deformities, may also occur.
