What symptom expression does polio have

summary

I believe that everyone is familiar with polio. This disease often appears in our daily life, and now more and more children suffer from polio, which seriously affects their physical and mental health. So, what are the symptoms of poliomyelitis? Let's learn about it, and hope to help you.

What symptom expression does polio have

（1） Recessive infection (asymptomatic type): 90-95% of all infected patients. After infection, no symptoms appeared. The virus reproduction only stayed in the digestive tract, did not produce viremia, and did not infiltrate into the central nervous system. However, the virus could be isolated from the pharynx and feces, and specific neutralizing antibodies could be found in the body.

（2） Contusion type (mild): About 4-8%, the virus invades non nervous tissues of the whole body. The clinical symptoms are lack of specificity, such as: (1) upper respiratory tract inflammation symptoms, such as fever, pharyngeal discomfort, pharyngeal congestion, lymphoid tissue hyperplasia in the posterior pharyngeal wall, tonsillar enlargement, etc.; (2) gastrointestinal symptoms, nausea, vomiting, diarrhea or constipation, abdominal discomfort, etc.; (3) influenza like symptoms, joint and muscle soreness, etc. The symptoms lasted for 1-3 days and recovered spontaneously.

（3） Non paralytic type: poliovirus invades the central nervous system, and the circulating nerve fibers spread throughout the body, which can appear the symptoms at the beginning of the disease, but most patients can enter this stage after 1-6 days of asymptomatic or symptom relief.

matters needing attention

The earlier we treat it, the better the effect will be, so as to avoid delaying the development of the disease and causing serious consequences. Do a good job in daily nursing, strengthen sports training, give more encouragement and support to children, avoid bringing negative emotions to children, is not conducive to the development of the disease.
