One of the worst outbreaks ever documented took place in Czechia, in a swimming pool where, unknown to the management, a cavern full of stagnant water formed behind one end of the pool. 16 young people died in a span of a few weeks.

There was recently a case of this in Louisiana. The 4th since 1937. It's exceedingly rare.
