Deaths from the "brain eating amoeba" Naegleria fowleri are fairly rare but each is highlighted in the press, as headlines containing brain eating beget clicks.
While it's not yet understood why this fresh water amoeba is a pathogen and ends up in the brain specifically; molecules in neurons may be structurally similar to molecules the amoeba is sensitive to and moves towards (1, 2).
Are there any guidelines to help reduce risk of exposure to, or infection of Naegleria fowleri when dealing with exposure to fresh water ponds, lakes, or rivers for recreation or even just washing-up ones self?
