I had consulted a couple of doctors and even after the high fees they hardly answer your queries and they were barely aware about N Fowleri infection risk. I am grateful to Doctors who clear my doubts here. Big thank you. Sorry for repeated queries, psychologist can't help as in past for panic attacks I had tried consulting one. Is it possible that if some dirty water or unchlorinated water drops fall into the mouth and nose while laughing and if we cough or gasp, inhale a bit deeply by mistake like in a sneeze or while trying to stop a cough, can we get infected if N Fowleri present in the water drops? Can one get infected while brushing teeth with unchlorinated water?
