A teenager in North Carolina has died after contracting a rare and nearly always fatal brain infection linked to a public water feature in Durham. The North Carolina Department of Health and Human Services confirmed the case and issued guidance for the public on how the infection occurs and how to reduce risk.
The infection is caused by Naegleria fowleri, a microscopic organism found naturally in warm freshwater. It can enter the body through the nose, travel along olfactory nerves, and reach the brain, causing primary amebic meningoencephalitis — a disease that progresses rapidly and carries a fatality rate exceeding 97 percent. NCDHHS says 167 cases were reported nationally between 1962 and 2024, which shows how rare the infection is. The Durham community-organization water feature was identified as the most likely exposure source. NCDHHS’s own language uses the phrase “most likely” — the investigation did not conclusively establish the water feature as the confirmed source. The feature was closed August 28. Subsequent CDC laboratory testing found Naegleria fowleri present in the water.
Naegleria fowleri infections carry a fatality rate exceeding 97 percent. Swimmers should wear nose clips, keep their heads above water, and prevent children from playing near decorative water fountains that lack verified chlorination systems. If you use a neti pot or sinus rinse bottle at home, only use boiled, sterile, or distilled water. Never flush nasal passages with untreated tap water. The organism does not cause illness when swallowed — infection occurs only when contaminated water is forced under pressure into the nasal cavity.
Why Rising Temperatures Increase Freshwater Pathogen Risks
Naegleria fowleri is a thermophilic organism — it thrives in warm water. Its active temperature range runs from 80°F to 115°F (27°C to 46°C). As summer heat extends the period that freshwater bodies and outdoor water installations remain within that range, the window of risk grows.
NCDHHS has not described the Durham feature as a confirmed runoff system or tied it to a specific sustainability policy. What officials have said is narrower and more important: the feature was identified as the most likely exposure source, was closed, and CDC laboratory testing found the organism in the water.

The regulatory gap here is specific: public swimming pools must meet mandatory chlorination standards. Decorative fountains, cooling basins, splash pads, and similar installations can operate in many jurisdictions without the same requirements. Properly chlorinated water kills Naegleria fowleri rapidly. Unchlorinated or poorly maintained installations at elevated temperatures create conditions where the organism can multiply.
The organism cannot infect someone through drinking or swallowing water. Infection requires water entering the nose under pressure — from diving, jumping, or forceful contact with water. [LINK: Safe water sterilization for neti pots and sinus rinses]
Watch for symptoms that appear between one and nine days after freshwater exposure: severe headache, fever, nausea, and stiff neck. These can resemble bacterial meningitis. If symptoms follow known freshwater exposure, seek emergency care immediately and tell medical staff about the exposure. Treatment options exist but must begin quickly.

FAQ
Can you get Naegleria fowleri from a splash pad or fountain? Yes, if the installation is unchlorinated, poorly maintained, or holds standing water above 80°F. Infection occurs when contaminated water is pushed into the nasal cavity under pressure. Properly chlorinated splash pads that maintain required disinfectant levels destroy the organism. Decorative recirculating fountains without chlorination systems carry higher risk.
Can you get infected by drinking water containing the amoeba? No. Naegleria fowleri does not cause infection when swallowed. The organism is destroyed by stomach acid. Infection occurs only when contaminated water enters the nose. NCDHHS specifically states that swallowing contaminated water does not cause primary amebic meningoencephalitis.
What kills brain-eating amoeba in water? Adequate chlorination is the primary control method. Naegleria fowleri is rapidly destroyed in properly maintained chlorinated water. Maintaining the required free chlorine residual and keeping water temperatures below the organism’s active range reduces risk in public water installations significantly.
