A 17-year-old North Carolina boy died after contracting a rare, nearly always fatal brain-eating amoeba, and state health investigators now say a water feature at a Durham County community center was the most likely source.
Moises Ponce Mendoza splashed water on his face at a garden water feature on Aug. 13 at El Futuro, a community-based mental health care center in Durham County. Five weeks later, he was dead. The North Carolina Department of Health and Human Services released an investigation report on Sept. 15 identifying that water feature as the probable point of exposure to Naegleria fowleri, a microscopic amoeba that enters the body through the nose, travels to the brain, and destroys tissue with devastating speed.
The amoeba causes a condition called primary amebic meningoencephalitis, a brain infection that kills more than 97 percent of the people who develop it, USA Today reported. Fewer than 10 cases are reported in the United States each year, and only 167 infections were documented nationally between 1962 and 2024.
The NCDHHS report laid out what investigators found when they examined El Futuro's outdoor water feature: algal growth throughout the manmade creek, organic material and debris surrounding the pump system, and a filter covered in buildup. The feature, an interactive, recirculating creek with multiple fountains, a play water pump, and a fire hydrant-style fountain, had been maintained through power washing and hand-fed chlorination, the center reported. Investigators concluded that approach fell short.
Testing at the Centers for Disease Control and Prevention detected non-viable Naegleria fowleri DNA in the fountain's storage tank water. The state report noted that "the lack of effective disinfection, visible algal growth, and detection of non-viable N. fowleri from the water feature support this conclusion" that El Futuro was the most likely exposure source.
State investigators stopped short of certainty. The report stated plainly:
"While this investigation does not allow us to conclusively determine the location of exposure, the epidemiologic, laboratory, and environmental findings suggest that the El Futuro water feature was the most likely source."
But the evidence pointed in one direction. Investigators traced every water contact Moises had in the weeks before he fell ill. His family reported he swam at an apartment complex pool on Aug. 11 and Aug. 17. Planned visits to two ponds on Aug. 5 and Aug. 6 were also flagged, though it remained unclear whether the teen actually visited or entered the water at either location. Family members identified El Futuro as a potential exposure site during a follow-up interview, and the Aug. 13 contact, when Moises splashed water from the feature onto his face, lined up with the infection timeline.
Symptoms of Naegleria fowleri infection typically appear about five days after exposure, though they can surface anywhere from one to 12 days later. They can lead to death within roughly five days of worsening.
Moises first went to an emergency room on Aug. 21 with a severe headache that had persisted for two days. His mother, Monica Mendoza, said the family was sent home after a brief examination. She brought him to the University of North Carolina Hospital's emergency department the next morning after his condition deteriorated sharply.
Monica Mendoza described the onset in a GoFundMe page for her son:
"It all started with severe headaches. I never imagined that something like this could be so serious."
Doctors suspected a Naegleria infection upon admission based on the teen's neurological symptoms and reports of freshwater swimming exposure. Laboratory testing confirmed the infection on Aug. 26. Moises was placed in a coma as doctors worked to treat the brain infection. He died on Aug. 31, four days after state health officials publicly reported he was critically ill.
The fatality rate tells the story of how little medicine can do once the amoeba reaches the brain. Dr. Jeffrey Kahn, chief of pediatric infectious diseases at UT Southwestern and Children's Health, explained the grim reality to Fox News:
"Once that happens, it's nearly a lethal disease. The mortality rate is close to 100%. By the time the [amoeba] enters the brain and starts to basically erode the brain tissue, it's too late."
The Durham County Department of Health advised El Futuro to close the water feature on Aug. 28. The center complied and subsequently drained the feature "to ensure it would not be used," the state report noted. It remains closed.
El Futuro acknowledged the findings in a public statement, saying that NCDHHS and Durham County Public Health had "informed El Futuro that testing identified the presence of Naegleria fowleri in a water feature at our green space." The center added:
"Our hearts are broken for the young boy who lost his life and for his family. We are committed to supporting his family and our community through this devastating loss. We will continue to fully cooperate with public health officials."
The statement did not address how long the water feature had been in operation, whether anyone had tested the water quality before the state investigation, or what specific maintenance schedule the center followed beyond power washing and hand-fed chlorination. The state report did not indicate whether any regulatory action or legal consequences are under consideration.
Moises Ponce Mendoza's death was not the only Naegleria fowleri fatality this summer. An 8-year-old Louisiana girl died on Aug. 22 after contracting the same infection, making two fatal cases in a matter of days, an unusual cluster for an organism that claims fewer than 10 victims per year nationwide.
The NCDHHS news release offered context for why the infections tend to arrive in summer. "These rare infections usually occur when it is hot for prolonged periods of time, which results in higher water temperatures and lower water levels," the agency said. Naegleria fowleri thrives in warm, stagnant freshwater and "grows best at higher temperatures up to 115°F."
The amoeba enters the body through the nose, not by swallowing water, which means any activity that forces water up the nasal passages in contaminated freshwater carries risk. Splashing water on the face, as Moises reportedly did at the El Futuro feature, fits that profile.
Recreational water hazards have made headlines repeatedly this year. Fecal bacteria forced closures at Atlantic City beaches after contamination levels tripled New Jersey's safety limit, another reminder that the water people swim and play in is only as safe as the systems meant to keep it clean.
The North Carolina case stands apart because the exposure did not happen at a lake, river, or natural body of water. It happened at a manmade water feature designed for community use, one maintained with methods that state investigators found inadequate. A recirculating creek with fountains and a play pump, covered in algae, with a debris-clogged filter, is not a wilderness risk. It is a maintenance failure.
Warm-weather dangers in and around water have taken many forms this year, from animal attacks to flash flooding. But the Naegleria cases carry a particular cruelty: by the time anyone knows the amoeba was there, the damage is done.
Several gaps remain. The NCDHHS report detected non-viable Naegleria fowleri DNA in the fountain storage tank, and separate CDC testing confirmed the amoeba's presence in the water feature, but whether a live organism was found, or only genetic traces, is not entirely clear from the published findings. The water temperature at the time of Moises's Aug. 13 visit was not disclosed.
Whether El Futuro faces any regulatory penalties, fines, or civil liability is also unaddressed. The state report did not say whether the investigation is ongoing or concluded. And the question of who, if anyone, was responsible for ensuring the water feature met public health standards has no public answer yet.
A 17-year-old boy splashed water on his face on a summer afternoon. Eighteen days later, he was gone. Families deserve to know that the places their children play are maintained well enough to keep them alive, and when they aren't, someone ought to answer for it.
