Person in Missouri Contracts Rare 'Brain-Eating' Amoeba; Had Visited Lake of the Ozarks Before Falling Ill
The Missouri Department of Health confirmed the infection with Naegleria fowleri, which has caused 167 US cases since 1962 and is nearly always fatal, with only four survivors.
- A Missouri resident was confirmed infected with Naegleria fowleri, a brain-eating amoeba, likely contracted while water skiing at Lake of the Ozarks in August 2025.
- This infection occurs when the amoeba enters the nose from warm freshwater, and preliminary reports suggest Lake of the Ozarks exposure days before symptoms began.
- Naegleria fowleri causes primary amebic meningoencephalitis , a nearly always fatal brain infection with early symptoms like headache, fever, and nausea progressing rapidly to death.
- Since 1962, 167 U.S. cases of PAM were reported with only four survivors, and infections remain rare despite the amoeba's widespread presence in warm freshwater.
- Health officials advise recreational water users to assume the amoeba is present in warm freshwater nationwide and recommend precautions such as holding the nose to reduce infection risk.
