Poliomyelitis is an acute infectious disease caused by viruses invading the blood circulation system. Some viruses can invade the nervous system. Most patients are children aged one to six. The main symptoms are fever, general discomfort, limb pain, and paralysis in severe cases. It is commonly known as polio. Parents should understand the early symptoms of polio in infants so that they can receive timely treatment to avoid missing the best time for treatment.

The incubation period of polio is 5-14 days, and it can be clinically divided into several types: latent infection, abortive type, non-paralysis type, and paralysis type.

Early symptoms of polio

1. The symptoms of prodromal polio include fever, fatigue, general discomfort, upper respiratory tract infection and gastroenteritis, which last for 1-4 days.

2. In the early stage of paralysis, fever may occur again 1-6 days after the disappearance of the prodromal symptoms (bimodal fever). In this stage, the patient may enter directly from the prodromal stage or develop the disease directly in this stage, with symptoms such as high fever, severe headache, vomiting, stiff neck, positive Klinefelter's sign, etc. At the same time, the symptoms of polio often include muscle pain all over the body, sweating, etc.

3. The paralysis period is usually 2-7 days. Paralysis occurs when the body temperature begins to drop and gradually worsens until the body temperature returns to normal.

Spinal type: The most common type, presents as asymmetric flaccid paralysis, mostly affecting the lower limbs, followed by the upper limbs. The neck and back muscles, diaphragm, and intercostal muscles may also be paralyzed. The proximal large muscle groups are paralyzed earlier and more severely than the distal small muscle groups, and sensation is mostly unaffected.
