Rare Brain-Eating Amoeba Confirmed at Durham Water Feature After Teen's Death
A water feature at a Durham community organization has been identified as the most likely source of a rare and fatal brain infection that killed a North Carolina teenager last month, state health officials announced this week. The news has renewed attention on Naegleria fowleri, an amoeba commonly found in warm freshwater that can cause a devastating brain disease when it enters the nose.
The North Carolina Department of Health and Human Services (NCDHHS) said its investigation did not conclusively determine where the teen was exposed, but environmental testing and interviews pointed to the water feature at El Futuro, a nonprofit mental health organization serving Latino families in Durham County. The teen, identified by family as 17-year-old Moises Ponce Mendoza, died on Aug. 31 after being hospitalized on Aug. 22.
According to officials, the teen had contact with the water feature on Aug. 13, including splashing water on his face. The Durham County health department closed the feature on Aug. 28, and testing later confirmed the presence of Naegleria fowleri. The feature remains closed to the public.
Investigation and Testing
Investigators interviewed family members to trace possible exposure sites, including an apartment complex pool the teen visited on Aug. 11 and Aug. 17, and two ponds he may have visited on Aug. 5 and Aug. 6. However, of 11 samples taken from water sources in Alamance, Orange, and Durham counties, only the El Futuro water feature tested positive for the amoeba. The CDC supported the testing.
"NC Department of Health and Human Services and Durham County Public Health informed El Futuro that testing identified the presence of Naegleria fowleri in a water feature at our green space," the organization said in a statement. "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."
What Is Naegleria Fowleri and How Does It Infect?
Naegleria fowleri is a single-celled, free-living amoeba that thrives in warm freshwater environments such as ponds, lakes, rivers, hot springs, and poorly maintained swimming pools. It grows best at temperatures up to 115°F and feeds on bacteria in the water. Infections are extremely rare; from 1962 through 2024, only 167 cases were reported in the United States, with typically fewer than 10 cases per year.
Infection occurs when contaminated water enters the nose, often through splashing, diving, or other water activities. The amoeba travels along the olfactory nerve to the brain, causing primary amebic meningoencephalitis (PAM), a condition that is almost always fatal. It cannot be spread from person to person, and drinking contaminated water does not cause infection.
Symptoms and Progression
Early symptoms of PAM can include severe headache, fever, nausea, and vomiting. As the disease progresses, symptoms may include stiff neck, seizures, and coma. Health officials note that once symptoms start, the disease progresses rapidly and usually causes death within about five days. This highlights the importance of seeking immediate medical attention if symptoms appear after contact with warm freshwater.
Water Feature at El Futuro: What We Know
The water feature at El Futuro is described as similar to a splash pad and man-made creek located outside the facility as part of its "green space initiative." It is not a water fountain, though it includes a sprinkler and pump designed to encourage play and interaction. The feature was closed on Aug. 28 when testing began.
Despite the shallow water, officials emphasize that any contaminated water that goes up the nose, even through splashing, can pose a risk. It does not need to enter the nose with force. This serves as a reminder that recreational water activities, even in seemingly low-risk settings, can occasionally lead to infection.
Context: Why This Case Matters
This case is the first known instance in North Carolina where a community water feature has been linked to a Naegleria fowleri infection. While the amoeba is naturally present in warm freshwater, cases like this raise questions about the safety of man-made water features that may not be adequately chlorinated or maintained. El Futuro has expressed its commitment to cooperation and support for the family.
The rarity of the infection makes it difficult to draw broad conclusions, but public health officials stress that awareness and precaution are key. The investigation involved multiple agencies, including the CDC, and took extensive sampling to identify the likely source.
National and Global Perspective
Globally, roughly 488 cases have been documented since 1962. In the U.S., the majority of cases have occurred in southern states, particularly Texas and Florida. Climate change and warming waters may increase the geographic range of the amoeba, though data remains limited. The CDC has been monitoring the situation and provides guidance on prevention.
Prevention and Public Health Guidance
Health officials recommend avoiding water-related activities in warm freshwater during periods of high water temperature and low water levels. When participating in such activities, individuals can reduce risk by using nose clips, keeping their heads above water, and avoiding digging or stirring up sediment in shallow warm water. It is also important to properly maintain swimming pools and other water systems with adequate chlorine levels.
For water features like splash pads, proper disinfection and regular testing are essential. The NCDHHS has not issued a statewide advisory but encourages local health departments to review maintenance protocols for similar features.
What This Means for Communities
This case serves as a tragic reminder that rare infections can occur even in familiar settings. Communities with man-made water features should ensure they are properly chlorinated and monitored. The Durham County health department has been working with El Futuro to ensure the feature remains closed until it is deemed safe.
As investigations continue, the family of Moises Ponce Mendoza mourns a young life lost. The community has rallied in support, and El Futuro has extended condolences. Public health officials emphasize that while the risk is low, awareness can save lives.
Conclusion
The confirmation of Naegleria fowleri in a Durham water feature underscores the importance of water safety and public health vigilance. While infections are exceedingly rare, the outcome is almost always fatal, making prevention crucial. As temperatures rise and water activities continue, health officials urge the public to be mindful of the risks and to take simple precautions to protect themselves and their families.
