Brain-Eating Amoebas
While very rare, the threat of contracting a brain eating amoeba called Naegleria while swimming in pool waters is very real. In fact, a 12-year-old Arkansas girl is thought to have contracted it back in 2010.
Given that only two people in North America are known to have survived the rare infection, you’d best bet that you won’t find me anywhere near pools anytime soon.
