I had read that you cannot get N Fowleri by drinking contaminated water. My concern is that sometimes we may have to drink water that may not be chlorinated or may be infected like in rural area. So if I just drank contaminated water and blew my nose as soon as I drank it, can the water go up or be pulled up in the upper nasal passages near the olfactory nerves to cause an infection through postnasal drip or any other way? Can one get infection of N Fowleri like this if N Fowleri was by chance present in the water?
