Thanks for the references. Skimming through them it seems it's only the case for warm freshwater. Citing from your 1st reference: > Naegleria fowleri infects people when water containing the ameba enters the body through the nose. This typically occurs when people go swimming or diving in warm freshwater places, like lakes and rivers. Does it mean sea water is safe or at least safer?
