What are the symptoms of polio?

Polio is an infectious disease that seriously endangers the physical and mental health of children, causing harm to the child's entire body. I hope friends can be alert to the occurrence of paralysis and have a thorough understanding of the symptoms of the disease in life. So, what are the symptoms of polio? I hope the following introduction will be helpful to you.

Poliomyelitis starts with fever, headache, diarrhea, vomiting and general discomfort. Parents often think it is a cold or indigestion. The fever subsides after 1-4 days, and a few days later, the fever reappears, and it is higher than the first time. The prominent manifestation is hyperesthesia-like pain, not allowing others to touch, accompanied by blushing, headache, sore throat, vomiting, sweating, and then drowsiness. Paralysis occurs after 3-7 days, and the most common part is the lower limbs. One week after the paralysis occurs, if it does not continue to develop, it can gradually recover.

If you go to the hospital for treatment in time, polio can be cured. In the past, some long-term sequelae that could not be recovered were once considered "incurable diseases"; now there are treatments such as acupuncture, massage or surgery. There are polio patients in the people around the patient. The patient has the above-mentioned symptoms of polio, such as fever, limb pain, limb paralysis, etc. The patient's limb paralysis is flaccid paralysis (i.e., loose and weak limbs), muscle atrophy, and thinning of the limbs. The child has normal intelligence and normal bowel and bladder functions. The child is normal after birth, and develops limb paralysis due to fever after growing up to 6 months. There are various deformities of limb paralysis, and the degree of lesions in the limbs is asymmetrical; the diseased limbs are cold due to poor blood circulation, but feel normal.

It is an infectious disease caused by polio virus. Because the disease mainly changes in the anterior horn cells of the spinal cord and the motor nerves of the brain stem, it is medically called poliomyelitis. This disease can cause muscle weakness and partial limb paralysis. Because it often occurs in children, it is also called "infantile paralysis." The polio virus is mainly excreted from the patient's feces, and the detoxification time is very long, up to 5-6 weeks or longer. The main transmission route is through pollution sources, food, hands, flies, etc., and then transmitted through the digestive tract. After the virus invades the body, it enters the lymph nodes and blood circulation from the throat, and then invades the spinal cord, brain, and nervous system, making people sick. Symptoms usually appear 7-14 days after the virus invades the body.

After comprehensively understanding the above knowledge, everyone has a clearer understanding of the symptoms of polio. The onset of paralysis will harm the health of children's legs and bring more obstacles to their development. I hope that parents can pay attention to changes in their children's legs and the disease should be treated in time.
