Naegleria fowleri infections are rare*. In the 10 years from 2009 to 2018, 34 infections were reported in the U.S. Of those cases, 30 people were infected by recreational water, 3 people were infected after performing nasal irrigation using contaminated tap water, and 1 person was infected by contaminated tap water used on a backyard slip-n-slide.

34 infections in 9 years seems rare to me.

But there is no commonly accepted definition of rare.

But you could safely say that most doctors will never see a case.

But you could safely say that most doctors will never see a case.

Which means that it is probably underdiagnosed (if that is a word).

About 3.5 cases per year. That’s rare. There’s more bubonic plague in the U.S.!
