Researchers Identify Brain-Eating Amoeba in U.S. National Park Hot Springs, Raising Health Concerns
A recent study has identified the presence of Naegleria fowleri, commonly known as the brain-eating amoeba, in hot springs and hydrothermally fed waters across several popular U.S. national parks, including Yellowstone, Grand Teton, and Lake Mead Recreation Area. The Centers for Disease Control and Prevention (CDC) reports that this pathogen, although rare, is highly lethal, with a 98% fatality rate among those infected. The amoeba thrives in warm freshwater environments and can cause Primary Amebic Meningoencephalitis (PAM) when it enters the human body through the nose. Researchers from the U.S. Geological Survey and Montana State University conducted the study, finding the amoeba in 34% of the water samples tested. The study highlights the need for increased public awareness and risk management strategies in these recreational areas.
