Health authorities in Missouri are issuing urgent warnings after confirming a tragic death from a rare but almost always fatal infection. The victim, whose identity has not been released, contracted primary amoebic meningoencephalitis (PAM) after recent exposure to the waters of Lake of Three Fires in Taylor County, Iowa.
The culprit is Naegleria fowleri, a microscopic, single-celled amoeba found in warm freshwater. The infection occurs when contaminated water is forced up the nose, allowing the amoeba to travel to the brain. It then destroys brain tissue, causing a devastating and rapid inflammatory response.
What Are the Symptoms?
The initial signs of PAM are deceptively mild and can be mistaken for other illnesses, which is why it is so critical to seek immediate medical attention if you develop symptoms after swimming. They typically start about five days after infection and include:
- Severe headache
- Fever
- Nausea and vomiting
- Stiff neck
Later symptoms rapidly progress to:
- Confusion and disorientation
- Seizures
- Hallucinations
- Coma
How to Stay Safe This Summer
Despite the alarming nature of this infection, it is exceedingly rare. Health officials emphasise that the risk is low, but recommend simple precautions for anyone enjoying lakes, rivers, or hot springs:
- Hold your nose shut or use nose clips when jumping or diving into water.
- Avoid submerging your head in warm freshwater, particularly in areas known to have the amoeba.
- Stay away from stirring up sediment at the bottom of lakes.
It is crucial to remember that you cannot get infected by drinking contaminated water, and the disease is not contagious.
The Lake of Three Fires remains closed to the public as the investigation and testing continue. This tragic event serves as a sobering reminder of the importance of water safety awareness during the warm summer months.
