Heat-Driven Spread Expands Brain-Eating Amoeba Risk in North Carolina
Rising temperatures are linked to a northward shift and longer potential season for exposure to the brain‑eating amoeba Naegleria fowleri, highlighted by a central North Carolina teenager in critical condition. A 2021 CDC study found exposures moving north over four decades, though overall cases remain extremely rare and no nationwide increase is detected. Officials stress prevention (nose clips, keeping the head above water, avoiding disturbed sediment) and sustained surveillance as climate warming could broaden where and when PAM risk exists.
