A pandemic-weary public already facing the uncontrolled spread of COVID-19 and monkeypox is feeling jittery about the resurgence of a dreaded disease that was thought to be largely eradicated.

But experts say the U.S. is highly protected from the widespread transmission of polio, at least in areas that are highly vaccinated.

What they’re saying: “If you’re an unvaccinated person living in Rockland or Orange County (New York), where sewage is showing there’s polio in it, I would be concerned and get vaccinated,” Aaron Glatt, infectious disease chief at Mount Sinai South Nassau, told Axios.

Glatt and several other experts interviewed by Axios said those current on their shots have little reason to be concerned. About 93% of children in the U.S. are vaccinated against polio by their second birthday and received nearly full protection, per the CDC.
