Why do children are more likely to get poliomyelitis than adults?

Children are more likely to get poliomyelitis than adults primarily because they have not yet developed immunity to the poliovirus, often due to lack of vaccination or previous exposure. The virus tends to spread in areas with low vaccination rates, and children are more frequently in close contact with each other, increasing transmission risk. Additionally, children's immune systems are still developing, making them more susceptible to infections in general.
