The development of polio vaccines in the mid-twentieth century and a robust international response have helped more than one hundred countries become polio-free. New cases in the United States and Israel in 2022 underscore the risk that, until it is eradicated globally, polio can make a comeback in any part of the world. https://www.cfr.org/backgrounder/why-hasnt-world-eradicated-polio

No, it wasn't sanitary systems that stopped polio. It was the vaccine. If you are going to make such counterfactual claims, at least have a link to the source so we can all laugh at it.
