Almost no one has survived a brain-eating amoeba, as they call it. I am sorry for your inconvenience (though I always said Oregon was the last state I would ever choose to live) but this was in the water coming from their taps and hoses. People were afraid to take their kids to the lake, but thought filling a pool in the backyard from their own water was safe. Or letting them play in the tub to cool off. Or having one of those slide things outside with the hose was safe.
This amoeba cannot be treated. It has a 98% fatality attached to it.
