Found this. Confirms polio cases and also detectable in water, but that doesn't mean that the water is the source of infection. Just means the infected people are shedding it through urine or bathing or whatever. Seems to me like 10-100 cases wouldn't be enough, but who knows if they're using PCR where just one particle can be replicated enough to detect (wouldn't be anywhere near enough to make anyone SICK though - our immune systems deal with stuff all the time).

Could all be smoke to cover for vaccine side effects and scare folks some more. Guillain Barre has the same symptoms as polio, it's just said to be autoimmune response versus a viral infection.

Fear porn so people will be inclined to get the polio vaxx. I wouldn't get any vaxx.
