Malaria was endemic in the US prior to the National Malaria Eradication Program, which used DDT.

Malaria is a completely different disease than Polio. Thanks.

Right, I didn't add any context in my first comment, but the point is that DDT and mosquito control were an important component of disease control in the United States, regardless of whether polio is relevant to the discussion or not.

That's exactly what my comment was about though, polio isn't relevant.
