Teen's brain-eating amoeba infection probable linked to water feature. Thao Nguyen USA TODAY. Another measles death fuels vaccine debate as US cases rise.

Three Pennsylvania measles deaths intensify vaccine debate as the United States faces its largest outbreak in decades.

Notably, a North Carolina teenager who died after contracting a rare brain infection caused by a microscopic amoeba was most probable exposed through contact with a water feature at a local community center, according to state health office-holders.

Notably, the teen, identified by his family as 17-year-old Moises Ponce Mendoza, died on Aug. 31, four days after health authorities noted he was critically ill and undergoing treatment for the infection. The rare brain infection is caused by Naegleria fowleri, an amoeba that is commonly discovered in warm freshwater.

Notably, an investigation could not conclusively determine where the teen was exposed, according to a report published by the North Carolina Department of Health and Human Services on Sept. 15. But health authorities stated interviews and environmental testing indicated that a water feature at El Futuro, a community-based mental health care center in Durham County, was the most probable source.

Notably, the water feature was closed on Aug. 28 by the Durham County Department of Health and afterwards tested positive for Naegleria fowleri at the Centers for Disease Control and Prevention. The water feature remains closed to the public, according to health authorities.

"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 mental health care center remarked in an official note.

"Our hearts are broken for the young boy who lost his life and for his family, " the statement continued. "We are committed to supporting his family and our community through this devastating loss. We will continue to fully cooperate with public health authorities." Public health investigation trace feasible exposure locations.

According to the state health department's report, investigators interviewed family members to trace feasible exposure locations, including sites where he may have been swimming or in contact with warm freshwater.

For context, the family informed investigators that the teen had gone swimming with family and friends at an apartment complex pool on Aug. 11 and Aug. 17 and had planned visits to two ponds on Aug. 5 and Aug. Though it was unclear whether he actually visited or swam in the ponds, the report states, 6.

During a follow-up interview, family members identified another potential exposure site at El Futuro, where the teen reportedly had contact with a garden water feature on Aug. As the report notes, 13, including splashing water on his face.

On Aug. 28, the Durham County Health Department advised El Futuro to close the water feature while investigators examined all potential exposure sites. The water feature was subsequently drained "to ensure it would not be used, " the report states.

Health authorities described the water feature as an interactive, manmade creek with a recirculating water system, multiple fountains, a play water pump, and a fire hydrant-style fountain. The mental health care center documented that the water feature was maintained through power washing and hand-fed chlorination.

As the report notes, during the inspection, investigators discovered algal expansion throughout the creek as well as organic material and debris surrounding the pump system and covering the filter. Testing afterwards detected non-viable Naegleria fowleri DNA in the mental health care center's fountain storage tank water.

"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, " the report states. "The lack of effective disinfection, visible algal growth, and detection of non-viable N. Fowleri from the water feature support this conclusion."

Health authorities stated the teen initially went to an emergency room on Aug. 21 with a severe headache that had persisted for two days. He returned the after day as his condition worsened and was admitted to the hospital.

"Upon hospital admission, Naegleria infection was suspected due to reports of freshwater swimming exposure and neurological presentation, " the report states. Laboratory testing confirmed it was a Naegleria fowleri infection on Aug. 26, and the teen died on Aug. 31.

In practice, the teen's mother, Monica Mendoza, remarked her son became severely ill after developing intense headaches, according to a GoFundMe page. She remarked she took her son to the hospital after his symptoms became severe and the family was sent home after a brief examination.

Naegleria fowleri is commonly discovered in warm freshwater, including lakes, ponds, and rivers. Health authorities say it does not cause illness when swallowed.

Notably, the danger occurs when contaminated water enters the nose, allowing the amoeba to travel to the brain and cause primary amebic meningoencephalitis, or PAM, an extremely rare but often fatal disease, according to the CDC.

Though they can appear anywhere from one to 12 days afterwards, according to the North Carolina Department of Health and Human Services, symptoms typically commence concerning five days after exposure. Early symptoms include severe headache, fever, nausea, and vomiting.

Symptoms can rapidly worsen, progressing to a stiff neck, seizures, and coma before often leading to death within concerning five days.

"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 state health department remarked in a news release. "Naegleria fowleri grows best at higher temperatures up to 115°F."

Meanwhile, the CDC notes fewer than 10 cases are noted in the United States each year, and more than 97% of individuals who develop the infection die. Naegleria fowleri infections are "very rare, with only 167 cases reported nationally between 1962 and 2024, " according to the state health department.

For context, the North Carolina case follows the death of an 8-year-old girl in Louisiana. This person died on Aug. 22 after contracting a Naegleria fowleri infection. State health authorities stated she may have been exposed while swimming in a Louisiana lake. Contributing: Anthony Thompson and Melina Khan. Share your feedback to support improve our site!
