Hello; Way to go off on a tangent and also to do some misinformation of your own. Given the choice I will take covid19 over polio every time. The common cold is also a respiratory virus and is also a corona virus by the way. Covid19 is much worse for some than the common cold. Covid19 is much less of a problem than the common cold for some folks . Many had asymptomatic infections with the covid19 virus, they did not even know that had been infected.We are awash in disinformation and misinformation that's aimed at disrupting our response to COVID-19 and otherwise hobbling us. All I keep saying is that we should listen to the experts on these issues.
COVID and polio are different. The polio virus is carried in feces and primarily infects young children after they touch contaminated water or dirt and then put their fingers in their mouths. From there, the virus can invade the brain and spinal cord, leading to paralysis and, in some cases, death. Adults are less at risk of infection, because of less exposure to the sewage and a greater likelihood of being vaccinated.
That's entirely different than a respiratory virus like COVID-19.
Back when I was a child there was not a polio vaccine for a long time. Not for adults and not for children. We lived thru it without lockdowns or school closures.
