What are the causes of polio?

What are the causes of polio? The causes of polio are mainly divided into four aspects: polio virus is transmitted orally through food, such as water contaminated by infected feces; the virus enters the blood circulation through the lymph, forming viremia, and the virus can break through the blood-brain barrier and invade the central nervous system; the virus replicates in the nervous system, leading to pathological changes; other factors such as excessive fatigue, strenuous exercise, intramuscular injection, tonsillectomy and genetic factors.

1. Genetic factors

Poliomyelitis sequelae are common in some families, with members of the family developing the disease many years apart. This cannot be explained by transmission within the family, but suggests the role of genetic factors.

2. Age, gender and pregnancy

The incidence of this disease is equal in male and female children, but the incidence of paralysis in boys is higher than that in girls. The incidence of this disease in adults is higher in females, but the incidence of paralysis is equal. The incidence of this disease is higher during pregnancy, and the condition is also more serious, which may be related to the suppression of immunity during pregnancy.

3. Injection and trauma

Limbs that have been injected or have been traumatized by fracture, surgery, or other reasons are more likely to become paralyzed.

4. Tonsillectomy

People who have had their tonsils removed in the recent or distant past are eight times more likely to develop post-polio symptoms than those who have tonsils removed.

5. Vigorous exercise

In the early stages of paralysis, strenuous exercise and fatigue can increase the incidence and severity of paralysis.

The above introduces the causes of polio. Through these causes of polio, everyone knows the main symptoms of polio. However, the treatment method can only relieve the patient's pain and cannot completely cure it. Therefore, we must pay attention to whether the patient has a psychological illness. Many children cannot tolerate long-term bed rest and cannot live like normal children.
