Interesting development: Doctors were treating a patient who had infections of both SARS-COV2 and polio virus, with Remdesivir. It knocked out both viruses! So it looks like they have an effective treatment for polio infection. Doctors usually discover a polio infection after paralysis begins, when it's too late to reverse the damage. Only about 1 in 200 of those unvaccinated and infected by polio get paralyzed. Most of those people don't even know their mild illness is polio.

But Remdesivir might be useful to limit the damage if given immediately as soon as symptoms appear. Polio is rampant in countries that do not vaccinate, like Pakistan. But since people who receive the oral polio vaccine shed infective virus for a couple of weeks, it could be useful for American anti-vaxxers who get exposed to the OPV vaccine-induced virus that is floating around.
