Naegleria infection is caused by an amoeba commonly found in warm, freshwater lakes, rivers and hot springs. Exposure to the amoeba usually occurs during swimming or other water sports. The amoeba — called Naegleria fowleri — travels up the nose to the brain, where it causes severe brain damage.

Most people who have naegleria infection die within a week of showing symptoms.
