Is polio hereditary?

Polio is generally not inherited because it is a disease caused by infection with the polio virus and has nothing to do with genes.

The disease is spread through contaminated water, food or saliva, rather than being passed from parent to child through genes. Polio affects the central nervous system, especially the spinal cord, and can cause muscle weakness or even paralysis, but its onset is mainly related to viral infection and the body's immunity.

Currently, polio vaccination can effectively prevent the occurrence of the disease. After a full course of vaccination, the body is able to build immunity against the virus, greatly reducing the risk of infection. Even if there is a case of polio in the family, it does not mean that the child will inherit the disease, but it needs to be careful to avoid contact with the source of viral infection.

Parents need to take their children to get the vaccines in the national immunization program on time and pay attention to personal and family hygiene. If you find that your child has muscle weakness or other suspicious symptoms, please see a doctor immediately so that the condition can be evaluated in time and appropriate treatment measures can be taken. Following the doctor's advice is an important step in protecting your child's health.
