Polio can be eradicated. The World Health Organization identifies three types of wild poliovirus; none can survive outside the human body. Research shows that if the poliovirus cannot find an unvaccinated person to infect, it will die out. The virus doesn’t even have an outbreak because we’re so heavily protected against it. Also, as devastating disease polio is, it’s limited because it only affects humans. According to Polioeradication.org, No poliovirus has been found to exist and spread among animals; therefore, it can’t spread as vastly as other diseases that affect humans and other animals. Lastly, we have a vaccine.
