The main symptoms of polio

We all know the harm of polio. This disease brings serious troubles to the healthy growth of children. We should master the symptoms of this disease, which can help us detect the disease in time. We should always pay attention to our legs. If any abnormality is found, we should seek timely treatment. So what are the main symptoms of polio?

Symptoms of polio:

During the epidemic season, if susceptible people come into contact with patients and develop symptoms such as sweating, irritability, hyperesthesia, sore throat, neck, back and limb pain, stiffness, and loss of tendon reflexes, this disease should be suspected. The prodromal period should be differentiated from general upper respiratory tract infections, influenza, gastroenteritis, etc. Patients in the early stages of paralysis should be differentiated from various viral encephalitis, purulent meningitis, tuberculous meningitis, and epidemic encephalitis B. The appearance of flaccid paralysis is helpful for diagnosis. The incubation period is 3 to 35 days, generally 7 to 14 days. According to the severity of symptoms and the presence or absence of paralysis, it can be divided into latent infection, abortive type, non-paralysis type, and paralysis type.

Hidden infection (asymptomatic type): no symptoms appear after infection, the virus reproduces only in the digestive tract, does not produce viremia, and does not penetrate the central nervous system, but the virus can be isolated from the pharynx and feces, and specific neutralizing antibodies can be found in the body. Abortive type (mild): the virus invades non-nervous tissues throughout the body. The clinical symptoms lack specificity, and may include ① symptoms of upper respiratory tract inflammation, such as varying degrees of fever, pharyngeal discomfort, pharyngeal congestion and hyperplasia of posterior pharyngeal wall lymphoid tissue, swollen tonsils, etc.; ② gastrointestinal symptoms, nausea, vomiting, diarrhea or constipation, abdominal discomfort, etc.; ③ flu-like symptoms, joint and muscle aches, etc. Symptoms last for 1 to 3 days and recover on their own.

Non-paralytic type: polio virus invades the central nervous system, and circulating nerve fibers spread throughout the body. Symptoms of this stage may appear at the beginning of the disease, but most patients may be asymptomatic or have reduced symptoms for 1 to 6 days after the prodromal period, and then enter this stage. Paralytic type: It is characterized by the clinical manifestations of the non-paralytic type, plus lesions involving the gray matter of the anterior horn of the spinal cord, the brain and cranial nerves, leading to muscle paralysis.

Wherever polio vaccines are widely used, the disease has almost disappeared. Every child should receive the Sabin oral vaccine (attenuated oral polio vaccine) in early infancy to protect against all three types of polio. As with many infections, children start out feeling sick, with fever and headache. They may vomit, be constipated, or have some diarrhea. Most cases do not progress to paralysis, and some recover completely. If some degree of paralysis remains after the acute infection is over, the child must continue to receive regular specialized treatment.

If someone in your community has polio, you should not let your child go to crowded places, especially to stores and movie theaters. You should not take your child to swimming pools, where there are many people. On the other hand, if you do not allow your child to meet his old friends, that would be too much. If you are always so careful, you will never let him cross the street. Doctors suspect that cold and fatigue can make children more susceptible to polio, but children should avoid them at all times.

Through the above information about the main symptoms of polio, do you all understand that polio patients are angels with broken wings. We should spend more time and effort to take care of them. Only in this way can they develop and grow normally. Since paralysis is extremely common, it has harmed the leg health of many children and also hindered their development. Parents and friends need to seriously understand the knowledge of polio and learn more about the symptoms of this disease.
