Introduction to polio knowledge

Poliomyelitis is also called poliomyelitis. This disease is particularly terrible. When a child becomes ill, it will cause great harm to the child's physical health. We need to understand relevant knowledge and do a good job of prevention. Let us now learn about the relevant knowledge of polio, hoping it can help you.

Poliomyelitis (hereinafter referred to as polio), also known as poliomyelitis, is an acute infectious disease caused by the polio virus. The main clinical manifestations are fever, sore throat and limb pain, and some patients may develop flaccid paralysis. During the epidemic, there are many cases of latent infection and no paralysis. The incidence rate in children is higher than that in adults. Before the universal vaccination, infants and young children were particularly prone to the disease, so it is also called infantile paralysis. The main lesions are in the gray matter of the spinal cord, and those with severe damage may have paralysis sequelae. Since the widespread use of vaccines to prevent this disease in the late 1950s, its incidence has dropped significantly. After smallpox was eradicated in the 1970s, polio has been set as the next target to be eradicated by the end of this century.

It is more common in patients with medullary respiratory paralysis, and can be followed by bronchitis, pneumonia, atelectasis, acute pulmonary edema, azotemia, hypertension, etc. In the acute stage, about 1/4 of patients have abnormal electrocardiograms, indicating myocardial lesions, which can be caused directly by viruses or secondary to severe hypoxia. Gastrointestinal paralysis can be complicated by acute gastric dilatation, gastric ulcers, and intestinal paralysis. Urinary retention is prone to urinary tract infection. Those who are severely paralyzed and bedridden for a long time have bone atrophy and decalcification, which can be complicated by hypercalcemia and urinary tract stones.

The above content is an introduction to polio knowledge. I hope parents and friends can learn more about it. In life, we must do a good job of prevention, so as to reduce the occurrence of the disease. When children become ill, we should take them for treatment in time and strengthen nursing work.
