Louisiana girl Lillian Smart dies from brain-eating amoeba in Lake Claiborne
The tragedy marks only the fourth recorded death from primary amoebic meningoencephalitis in Louisiana since 2011. Experts suggest the climate crisis may be contributing to the amoeba appearing in new regions.

While the Louisiana Department of Health announced on August 19 that a state resident had been hospitalized with the infection, officials did not publicly name the patient. The identity of the child was later confirmed through the "Love for Lillian" Facebook page and by family friends. In Ruston, more than two dozen businesses donated a portion of their sales to support the family during the week leading up to the child's death.

The pathogen causes primary amoebic meningoencephalitis, or PAM. Unlike many waterborne illnesses, PAM is not contracted by swallowing contaminated water, nor is it contagious between humans. Instead, the amoeba enters the body through the nose, where it travels directly to the brain.
*Naegleria fowleri* thrives in warm freshwater environments, such as ponds, rivers, and lakes. It is not found in saltwater or in swimming pools that are properly maintained and chlorinated.
The progression of the disease is rapid. Symptoms typically emerge about five days after the initial infection, beginning with:
- Headache, fever, nausea, and vomiting
- Stiff neck, seizures, and coma
This case is a rare occurrence in Louisiana. Since 2011, state records identify only three previous deaths associated with the amoeba: two in 2011 involving adults in St. Bernard and DeSoto Parishes who used tap water to rinse their sinuses, and one in 2013 involving a 4-year-old boy who played on a slip-and-slide in St. Bernard Parish. In that 2013 instance, CDC testing detected the amoeba in the parish water system.
Nationwide, the infection remains exceedingly rare. Between 1937 and 2025, only 180 cases were recorded in the US. However, the timing of these cases is highly concentrated; the CDC reports that nearly 91% of the 173 infections documented over roughly the past 90 years occurred in July and August.
Recent cases suggest the pathogen is expanding its reach. In 2023, a child in Little Rock, Arkansas, died after exposure at a country club splash pad. Experts suggest the climate crisis may be contributing to the amoeba appearing in northern and western regions of the US where it was previously uncommon.
Louisiana Governor Jeff Landry shared his condolences on X, asking for prayers for the Smart family and the Ruston community.
"We are heartbroken and honestly do not know what to do next. How do we put one foot in front of the other without our girl?"

Timeline of the Infection and Death
Lillian Smart was hospitalized on August 15, 2026, in the pediatric intensive care unit of a Ruston hospital. The Louisiana Department of Health issued a confirmation of the Naegleria fowleri infection on August 19, stating the exposure most likely occurred while the patient was swimming in Lake Claiborne. Lillian died on Saturday, August 22, one day after her 8th birthday, according to statements from her family shared via the "Love for Lillian" Facebook page and reported by The Guardian.
The severity of this specific pathogen is highlighted by data from the US Centers for Disease Control and Prevention, which indicates that approximately 97% of people who develop PAM die from the infection. While the total number of US cases remains low, the recent death of a child in Little Rock, Arkansas, in 2023, linked to a country club splash pad, aligns with the current Louisiana case in terms of age group and freshwater exposure, as reported by the NY Post.
Despite the medical efforts described by the family, the infection's progression proved insurmountable. The Smart family stated that everyone did everything possible to save the child, but the brain injuries were too severe. For the grieving parents, the next step remains an emotional struggle, as they admitted on social media that they do not know how to move forward without their daughter.
Community Support and Medical Response
During Lillian Smart's hospitalization, the community of Ruston organized a grassroots effort to assist her family. More than two dozen local businesses donated a portion of their sales to support the Smarts while the child remained in the pediatric intensive care unit, according to the "Love for Lillian" Facebook page and reporting by KNOE.
