We can, but if we’re not careful, it can come back.

After eradicating polio for decades, we saw a case for the first time in 2022. https://pmc.ncbi.nlm.nih.gov/articles/PMC9577438/

And given the drop in rates of immunization post covid, we can very expect more if the trend continues.

It’s weird that we require interventions that do have some documented risk to our own citizens so that foreigners can visit without restriction. If an illness is eradicated in our borders, why should we let in people who might have it? Odd tradeoff calculus.

Read up on herd immunity. The problem isn't specifically 'foreigners' but the general question of whether enough people are vaccinated to prevent the disease from roaring back when it inevitably - it is not possible to stop people from bringing diseases into the country - reoccurs.

		Thank you for being condescending. Why would you assume someone doesn’t know about herd immunity? You absolutely could require proof of immunization to enter a country. We don’t even try.
