I've posted before about this. Well today I was in a cleaning mood and afterward washed my hands with tap water and dish soap. After that, yes, I picked/scratched the inside of my nose. I've read that N. Fowleri can live on dry surfaces for up to 5 minutes, now I'm convinced I have it...again. We're on a well system, and in our community it's treated, but I'm still leary. There have been numerous times in the bath where my children have gotten our tap water up their nose, and I've also done it in the shower. I know the odds are very low, but can someone reassure me that I DON'T have it???
