In what is the first known case of primary amoebic meningoencephalitis (PAM) in the state of Kansas, the Sedgwick County Health Department was notified by the Centers for Disease Control and Prevention (CDC) of the presence of the deadly amoeba, Naegleria fowleri in a sample from a resident who died.

Health Department officials said Thursday that the victim’s infection likely occurred while swimming in Winfield City Lake in Cowley County.

Naegleria fowleri is a relatively rare, pathogenic amoeba found in warm or hot freshwater like lakes, rivers and hot springs. It is also possible to get it from dirty, unchlorinated or under-chlorinated swimming pools. This parasite is found worldwide, and in the United States it is found in mainly in the southern-tier states.

People typically get infected by swimming, jumping or playing in freshwater and get the water up their nose. From there the parasite travels to the brain and spinal cord and necrotizes or basically eats brain tissue. The disease is known as primary amoebic meningoencephalitis (PAM) and it has a very rapid progression. Typical symptoms may start after a day or two; headache, fever, nausea and vomiting. Later symptoms may include seizures, irrational behavior, hallucinations and finally coma and death. The course of the disease typically last about a week. Because the symptoms are very similar to bacterial meningitis, PAM may not even be considered in the diagnosis.

Fortunately, it’s a pretty rare disease, with only approximately 30 cases in the past decade. Unfortunately, treatment is usually unsuccessful with only a handful of people surviving infection.

You should always assume there is some risk when swimming in freshwater. The location and number of amoeba present in a body of water varies from time to time. The Centers of Disease Control and Prevention recommends these four steps to reduce your risk of infection:

• Avoid water-related activities in bodies of warm freshwater, hot springs, and thermally-polluted water such as water around power plants.

• Avoid water-related activities in warm freshwater during periods of high water temperature and low water levels.

• Hold the nose shut or use nose clips when taking part in water-related activities in bodies of warm freshwater such as lakes, rivers, or hot springs.

• Avoid digging in or stirring up the sediment while taking part in water-related activities in shallow, warm freshwater areas.
