Lillian Smart, 8, Dies One Day After Her Birthday Following Rare Naegleria fowleri Infection in Louisiana

RUSTON, LOUISIANA — An eight-year-old Louisiana girl whose community rallied around her family with prayers, fundraisers and messages of support has died after developing a rare and devastating infection caused by Naegleria fowleri, an organism commonly known as the “brain-eating amoeba.”

Lillian Smart, of Ruston, Louisiana, died on Saturday, August 22, 2026 — just one day after her eighth birthday. Her family had spent the previous week hoping and praying for her recovery as doctors fought to control severe swelling in her brain.

The Louisiana Department of Health confirmed earlier in August that a Louisiana resident had contracted Naegleria fowleri, saying the infection was most likely acquired while swimming in Lake Claiborne in northern Louisiana. Health officials did not initially identify the patient, but Lillian’s family later confirmed that she was the child who had been hospitalized. (The Guardian)

A Sudden Illness

According to accounts shared by Lillian’s mother, Rebecca Smart, the illness began on Thursday, August 13, when Lillian developed a fever and extreme fatigue.

At first, the symptoms did not immediately point to the extraordinarily rare infection that would ultimately claim her life. Tests for COVID-19, influenza and strep throat were reportedly negative. Yet her fever remained high, and her exhaustion became increasingly concerning.

By Saturday, August 15, the situation had changed dramatically.

Lillian began complaining that she was seeing double. Rebecca also noticed that her daughter’s pupils appeared different from one another. Recognizing that something was seriously wrong, Lillian’s parents took her to Willis-Knighton South Hospital in Shreveport, a facility with pediatric medical staff. (NTD)

Doctors performed a lumbar puncture and initially diagnosed bacterial meningitis, a condition whose early symptoms can resemble those of Naegleria fowleri infection.

Further testing eventually revealed the devastating diagnosis: Lillian had developed primary amebic meningoencephalitis, or PAM, caused by Naegleria fowleri. (The Independent)

A Race to Control the Brain Swelling

Lillian was admitted to the pediatric intensive care unit, where her condition deteriorated rapidly.

Her infection caused severe inflammation and swelling inside her brain. Doctors worked to treat the infection while simultaneously trying to control the dangerous pressure inside her skull. Medical teams also worked to stabilize her temperature and blood pressure as her condition became increasingly critical.

Her family remained close to her throughout the ordeal.

They asked friends, neighbors and people around the country to pray for Lillian, while relying heavily on their Christian faith during an unimaginable period of uncertainty.

The Ruston community responded with an extraordinary show of support.

Businesses, churches and residents organized events and fundraisers to help the Smart family. One of those efforts, known as “Love for Lillian,” took place around her eighth birthday, with local businesses contributing portions of their proceeds to support the family. (https://www.knoe.com)

The birthday celebration was especially poignant because Lillian was still in intensive care.

Instead of celebrating at home surrounded by friends in the way an eight-year-old normally might, her family and supporters marked the occasion while praying for her recovery.

A Child Remembered for Her Joy

Those who knew Lillian have remembered her not simply for the illness that ended her life, but for the happiness she brought to the people around her.

Local business owner Patricia Willis described Lillian as a child who was consistently joyful and said that she seemed to bring a smile wherever she went. (https://www.hawaiinewsnow.com)

That image — a young girl known for her smile and happiness — became an important part of the community’s effort to support her.

Her mother also portrayed Lillian as remarkably strong and someone who, even while critically ill, continued trying to smile.

For her parents, the days surrounding her birthday became some of the most emotionally difficult moments of their lives. They described having to confront decisions and circumstances far beyond what most parents ever expect to face.

Yet they continued to focus on Lillian’s life, their love for her and their faith.

What Is Naegleria fowleri?

Naegleria fowleri is a microscopic, free-living amoeba that naturally occurs in warm freshwater environments.

According to the Centers for Disease Control and Prevention, it can be found in warm freshwater such as lakes, rivers and ponds. In extremely rare circumstances, contaminated water can enter a person’s nose, allowing the organism to travel toward the brain and cause PAM. (CDC)

Importantly, the infection is extraordinarily uncommon.

The CDC says fewer than 10 cases typically occur in the United States each year. Despite the rarity of infection, PAM is almost always fatal. (CDC)

The Louisiana Department of Health said that approximately 180 confirmed Naegleria fowleri infections had been reported in the United States between 1937 and 2025.

Lillian’s case was also significant for Louisiana because health officials said it was the state’s first confirmed Naegleria fowleri infection since 2013. (CBS News)

Why the Illness Can Be Difficult to Recognize

One of the most frightening aspects of PAM is how quickly it can progress and how closely its early symptoms can resemble more common illnesses.

The CDC says early symptoms may include headache, fever, nausea and vomiting. As the infection progresses, patients can develop stiff neck, confusion, loss of balance, hallucinations, seizures and coma. (CDC)

The CDC also notes that the first symptoms usually appear around five days after exposure, although the incubation period can vary.

That similarity to bacterial meningitis can make early recognition challenging, particularly because Naegleria fowleri infections are so rare.

In Lillian’s case, her initial fever and fatigue were followed by neurological symptoms, including double vision and unequal pupils, before doctors identified the underlying infection. (NTD)

A Rare Risk in Warm Freshwater

Health officials believe Lillian most likely encountered Naegleria fowleri while swimming in Lake Claiborne.

The CDC says the amoeba thrives in warm freshwater and that most U.S. infections occur after swimming or diving in lakes, rivers or other warm freshwater environments during the summer months. (CDC)

However, officials emphasize that the risk remains extremely low.

The infection is not spread from person to person. A person also does not develop PAM simply by swallowing water containing the amoeba; the concern is contaminated water entering the nose. (CDC)

For people who choose to swim in warm freshwater, the CDC recommends reducing the amount of water that enters the nose. This can include holding the nose shut or using a nose clip when jumping or diving, keeping the head above water in hot springs, and avoiding disturbing sediment in shallow freshwater. (CDC)

A Family Left to Grieve

Lillian’s parents announced her passing in a heartbreaking message shared Sunday.

They wrote that Lillian had ultimately been unable to recover from the severe injuries to her brain and said that everyone involved had done everything possible to keep her alive. The family said they were heartbroken and did not know what life would look like without their daughter. (https://www.hawaiinewsnow.com)

Her death also prompted an outpouring of sympathy from Louisiana officials and the broader community.

Louisiana Gov. Jeff Landry publicly expressed his heartbreak over Lillian’s passing and asked people to pray for the Smart family and the Ruston community. (CBS News)

For those who knew Lillian, however, the story is not only about a rare infection.

It is about an eight-year-old girl remembered for her smile, her strength and the joy she brought to others.

Her final days were filled with medical uncertainty, but they were also surrounded by family, faith, community support and people who refused to let her family face the crisis alone.

Lillian Smart celebrated her eighth birthday on August 21.

The following day, she was gone.

Her family now faces the heartbreaking task of learning how to move forward without the little girl they loved, while the Ruston community remembers a child whose brief life touched far more people than she could ever have known.

Rest in peace, Lillian Smart.
