A 12-year-old boy has died from a brain-eating amoeba after swimming in a South Carolina lake over the July Fourth weekend

Officials with the Centers for Disease Control say climate change raising freshwater temperatures may contribute to conditions that allow the amoeba to thrive.

Most people who come into contact with Naegleria fowleri never get sick. The amoeba can only infect a person when contaminated water goes up the nose, often during swimming or diving. It then travels to the brain, where it destroys brain tissue.
