Polio is a highly infectious viral disease that can cause paralysis and even death. It is spread through contact with the feces of an infected person or through contaminated food or water. There is no cure for polio, but it can be prevented by vaccination.
The polio vaccine is one of the most effective vaccines available. It is safe and effective, and it has helped to reduce the incidence of polio by more than 99% since its introduction in the 1950s.
