This happened in Charlotte at the whitewater center three years ago. Not that “rare”.

In total numbers, I’m sure it’s “rare.”

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.

There are between 0 and 8 cases of this per year.

It is indeed rare (fortunately) considering how many people are in contact with warm water in the summer time.

Millions upon millions swim in fresh water ponds, lakes, streams and rivers every summer... and in a bad year less than 2 handfuls of people contract this. Its INCREDIBLY rare.... sadly it is usually fatal if you get it, but it is indeed INCREDIBLY RARE.
