summary

Children are the objects that we should focus on protecting, because children are still young and don't know how to express their discomfort. This requires us adults to understand some children's diseases and prescribe the right medicine to the case. For some common symptoms, let's popularize what polio is.

What is polio

First, polio, also known as polio, is an acute infectious disease caused by poliovirus. The main clinical manifestations are fever, sore throat and limb pain. Some patients may have flaccid paralysis. When epidemic, most cases are occult infection and no paralysis. The incidence of children is higher than that of adults. Before general vaccination, most cases are infants, so it is also called poliomyelitis.

Second, recessive infection (asymptomatic type): it accounts for 90-95% of all the infected people. After infection, there are no symptoms. The virus reproduction only stays in the digestive tract, does not produce viremia, and does not penetrate into the central nervous system. However, the virus can be isolated from the pharynx and feces, and specific neutralizing antibodies can be found in the body.

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

Therefore, we adults should pay more attention to children's physical health. We should take good care of children and not be careless. Especially when children are not able to protect themselves, if we don't pay attention at this time, it may cause unimaginable consequences. Everyone is responsible for protecting children.
