You know it stops being rare when it keeps happening. It soon will be impossible to swim in lakes and rivers, along with ponds soon. This is climate change. The warm weather, and wamer water is allowing these things to thrive.
I mean they've always been active in the South. Any warm unchlorinated water means they'll be there eating bacteria. They just very rarely accidentally find themselves in your brain and start eating that. They're so common that the amount of people who have antibodies against them from finding their way into some random orifice is very high.
It is one of my biggest semi-irrational fears but I had never considered that you could have antibodies for them.
Would that mean we could vaccinate for them?
Opposite actually. PAM is because they end up locked behind the blood brain barrier where the really effective immune cells can't get to them. A vaccination is pointless because they are already easily destroyed by immune cells otherwise. It's like accidentally wandering into a bank vault full of Cheetos while they were delivering more Cheetos and getting yourself locked in for fowleri. A poor situation for them and a poor situation for the Cheeto Bank.
