North Carolina Teen Dies From Rare Brain-Eating Amoeba Infection

A North Carolina teenager has died after contracting Naegleria fowleri, a rare brain infection linked to warm freshwater. Learn about symptoms, transmission, risks, and prevention.

A North Carolina teenager has died after developing a rare and extremely serious brain infection caused by Naegleria fowleri, an amoeba sometimes referred to as the "brain-eating amoeba."

The teenager died on Aug. 31, 2026, several days after North Carolina health officials confirmed that he was critically ill with the infection. The case has drawn attention to the dangers associated with exposure to warm freshwater, particularly during the summer months.

The North Carolina Department of Health and Human Services (NCDHHS) confirmed the teenager's death in a statement provided to news media. Health officials expressed condolences to the teenager's family, friends, and community.

The patient was initially not publicly identified by state officials. His mother later identified him as Moises Ponce Mendoza through an online fundraising campaign created while he was hospitalized.

What Happened to the North Carolina Teen?

According to information shared by Mendoza's family, Moises initially experienced severe headaches before his condition rapidly worsened.

His mother said she took him to a hospital in Burlington on a Friday night after his symptoms became concerning. Following an examination, the family was reportedly allowed to return home.

His condition deteriorated soon afterward.

Mendoza said she left work early the next morning and took her son to the emergency department at UNC Hospitals. Doctors subsequently determined that he had contracted Naegleria fowleri, a rare amoeba capable of causing a devastating infection of the brain.

According to the fundraising campaign, Moises eventually fell into a coma while doctors attempted to treat the infection.

His family publicly mourned his death following his hospitalization. A relative also shared a tribute online, remembering the teenager as a fighter and expressing love for him.

NCDHHS had initially announced the case on Aug. 27. At that time, officials said a teenager from central North Carolina was critically ill with a rare illness caused by Naegleria fowleri. Authorities did not release additional identifying information, citing the family's privacy.

Officials also said that the source of the infection was still being investigated.

What Is Naegleria Fowleri?

Naegleria fowleri is a microscopic amoeba that can live in warm freshwater environments. It is most commonly associated with lakes, ponds, rivers, and other bodies of freshwater that become warm enough to support its growth.

The organism can cause an extremely rare infection called primary amebic meningoencephalitis, commonly abbreviated as PAM.

PAM affects the brain and surrounding tissues and can progress very quickly. Although infections are rare, the disease is considered extremely serious and is frequently fatal.

The infection generally occurs when contaminated water enters the body through the nose. From there, the amoeba can travel along the olfactory nerve pathway toward the brain.

Importantly, simply swallowing water containing Naegleria fowleri does not cause the infection. The organism must generally enter through the nose for PAM to develop.

There is also no evidence that Naegleria fowleri infection spreads between people.

Symptoms of Naegleria Fowleri Infection

One of the challenges associated with PAM is that early symptoms can resemble other illnesses.

Initial symptoms may include:

• Severe headache
• Fever
• Nausea
• Vomiting

As the infection progresses, neurological symptoms can develop. These may include a stiff neck, confusion, hallucinations, seizures, and loss of consciousness.

The illness can progress rapidly, making urgent medical attention particularly important when someone develops severe symptoms following freshwater exposure.

Anyone who develops concerning symptoms after swimming or participating in activities involving warm freshwater should seek medical care promptly and tell healthcare professionals about the water exposure.

Where Is Naegleria Fowleri Found?

Naegleria fowleri prefers warm freshwater. It has been detected in environments such as lakes, ponds, rivers, and hot springs.

The risk is generally associated with warm water, especially during periods of high temperatures.

However, it is important to put the risk into perspective. Naegleria fowleri infections are extremely rare, even though millions of people swim in freshwater every year.

The presence of the amoeba in freshwater does not mean that a person who swims there will become infected.

Nevertheless, certain precautions can reduce the possibility of exposure.

How Can People Reduce the Risk?

Because Naegleria fowleri can enter through the nose, health authorities recommend taking precautions when swimming or participating in freshwater activities.

People can reduce exposure by avoiding activities that force warm freshwater up the nose. Using nose clips or keeping the nose closed when jumping or diving into freshwater may also help.

When possible, swimmers should avoid stirring up sediment in shallow, warm freshwater because organisms may be present in sediment.

People should also follow public health advisories and posted warnings concerning recreational water.

These measures cannot completely eliminate the possibility of exposure, but they can help reduce the risk.

Another Recent Fatal Case

Moises' death occurred shortly after the death of another child from the same rare infection.

Eight-year-old Lillian Smart of Louisiana died after developing Naegleria fowleri infection. State health officials said she likely contracted the amoeba while swimming in Lake Claiborne.

The two cases highlight the continued presence of Naegleria fowleri in warm freshwater environments in parts of the United States.

Despite the tragic outcomes, health experts emphasize that infections remain exceptionally uncommon.

Why This Case Is Receiving Attention

The death of the North Carolina teenager has renewed public awareness about a rare but potentially devastating consequence of freshwater exposure.

For families enjoying lakes, rivers, ponds, and other freshwater locations, the most important message is not to avoid freshwater altogether. Instead, people should understand how Naegleria fowleri is transmitted and take reasonable precautions.

The North Carolina case also illustrates how quickly PAM can progress once symptoms begin. Early symptoms may initially appear similar to more common illnesses, which can make recognition difficult.

Health authorities continue to investigate the circumstances surrounding the infection, including the possible source of the teenager's exposure.

For now, the case serves as a reminder that people should take unusual or severe symptoms seriously, particularly following recreational freshwater activities.

Final Takeaway

The death of North Carolina teenager Moises Ponce Mendoza following a Naegleria fowleri infection is a tragic reminder of the rare health risks associated with warm freshwater.

Naegleria fowleri can cause primary amebic meningoencephalitis, a rapidly progressing infection that affects the brain. The infection typically occurs when contaminated water enters the nose, rather than through swallowing water, and it does not spread from person to person.

While the infection is extraordinarily rare, people can reduce potential exposure by taking precautions when swimming in warm freshwater, avoiding water entering the nose, and following local health warnings.

Anyone experiencing severe headache, fever, vomiting, confusion, seizures, or other serious symptoms after freshwater exposure should seek immediate medical attention and inform healthcare providers about the exposure.
