KANSAS CITY, Kansas - A Johnson County resident has died following an infection caused by an amoeba found in freshwater, according to the Kansas Department of Health.

Authorities were unable to determine the source of the infection, citing “several potential fresh water exposures in Kansas,” the department stated in a news release.

The victim has been identified as 9-year-old Hally Yust of Spring Hill, Kansas.

The Kansas Department of Health and Environment was notified of a fatal case of primary amoebic meningoencephalitis (PAM) caused by Naegleria fowleri, a free-living amoeba found in freshwater.

The investigation indicates there were several potential fresh water exposures in Kansas, so the actual source of the infection cannot be determined.

This is the second known case of PAM caused by Naegleria fowleri in Kansas. The first case occurred in 2011 and Andrew Chavez of Wichita died after swimming in Winfield Lake.  KSN talked with Chavez’s mother days after. Check out YouTube video of KSN’s story from 2011.

Naegleri fowleri can be found in freshwater environments around the world, but infection causing PAM is extremely rare.

From 1962 to 2013, there have been 132 cases reported in the United States, with 34 of those cases occurring from 2004 to 2013. Most cases have occurred in southern-tier states.

The risk of infection is very low, but increases during the summer months when water temperatures rise and more people participate in water-related activities.

The infection typically occurs when the amoeba enters the body through the nose while the person is swimming underwater or diving and travels to the brain.

“We are very saddened to learn of this unfortunate circumstance, and our thoughts and prayers are with the family and friends during this difficult time,” said Robert Moser, MD, KDHE Secretary and State Health Officer, “It is important for the public to know that infections like these are extremely rare and there are precautions one can take to lower their risk – such as nose plugs.”

Symptoms usually appear about five days after infection, but can range between one and seven days, and include headache, fever, nausea and vomiting, stiff neck, confusion, lack of attention to people and surroundings, loss of balance and bodily control, seizures, and hallucinations. This infection cannot be spread from person to person or contracted from a properly maintained swimming pool.

Though the risk of infection is extremely low, the following precautions might decrease the possibility of infection:

  • Hold your nose shut, use nose clips, or keep your head above water when taking part in water-related activities in bodies of warm freshwater.
  • Avoid putting your head under the water in hot springs and other untreated thermal waters.
  • Avoid water-related activities in warm freshwater during periods of high water temperature.
  • Avoid digging in, or stirring up, the sediment while taking part in water-related activities in shallow, warm freshwater areas.
  • There is no known way to control the occurrence of Naeglaria fowleri in freshwater lakes and rivers.
