Deadly Brain-Eating Amoeba Strikes After Lake Swim

An eight-year-old Louisiana girl died after a rare brain infection likely tied to a summer swim.

Story Snapshot

Louisiana confirmed its first Naegleria fowleri case since 2013, linked to Lake Claiborne exposure.
The family said Lillian Smart, 8, died after severe brain injury from the infection.
Local outlets reported she was treated in a pediatric intensive care unit before she died.
Health officials say the amoeba infects people when warm freshwater enters the nose.

An August swim ended with a deadly, rare infection

Louisiana health officials confirmed a Naegleria fowleri infection in a Claiborne Parish resident and said the exposure likely happened in Lake Claiborne.

The agency called it the state’s first confirmed case since 2013. Family members identified the patient as Lillian Smart of Ruston and shared that she died after the infection caused severe brain injury. Local television reported she had been in a pediatric intensive care unit during the fight for her life.

Multiple national and local outlets reported the same core facts. An eight-year-old girl swam in a northern Louisiana lake, developed primary amoebic meningoencephalitis, and died days later.

The child’s family spoke publicly about her decline and their grief. Reporters cited the Louisiana Department of Health for confirmation of the infection and of the probable source of exposure at Lake Claiborne.

How this amoeba invades and kills

Naegleria fowleri lives in warm freshwater, like lakes and rivers, especially in late summer. Infection occurs when water is forcefully forced up the nose. The amoeba then travels along the olfactory nerve to the brain, triggering rapid, severe swelling.

The disease, called primary amoebic meningoencephalitis, almost always kills patients within about a week of symptoms starting, even with treatment. Headache, fever, stiff neck, vomiting, and confusion often appear early, then worsen quickly.

The Centers for Disease Control and Prevention says fewer than 10 people in the United States get this infection each year, and most do not survive.

From 1937 to 2025, the agency recorded about 180 United States cases, with annual counts ranging from 0 to 8. The risk is very low, but the outcome is often fatal. That is why health alerts draw wide attention even when only a single case appears.

Lake recreation, rare risk, and practical steps

Most recreational exposures to this amoeba occur in lakes, ponds, and reservoirs during the hot months. Divers, water skiers, and swimmers who dunk their heads and stir up warm, shallow water face a higher risk of getting water up their noses.

Doctors and health officials advise simple steps: avoid jumping or diving into warm freshwater, keep your head above water, use nose clips, and avoid stirring up sediment in shallow areas when water temperatures are high.

Parents can still enjoy summer at the lake, but need to choose deeper, cooler water when possible and skip underwater play during heat waves that raise water temperatures.

If a child develops a sudden, severe headache, fever, nausea, or confusion after exposure to freshwater, seek urgent care and tell clinicians about the swim. Early, aggressive treatment offers the only real chance, though outcomes remain poor in most cases.

What officials and the family have said

The Louisiana Department of Health linked the confirmed infection to likely exposure in Lake Claiborne and noted it was the first such confirmed case in the state since 2013.

Family members identified the child as Lillian Smart and said, “The injuries to her brain were too severe for her little body to recover from,” adding that everyone did all they could to save her. Local news reported her hospitalization in a pediatric intensive care unit before she died.

The facts point to a hard truth many do not expect from a summer swim. This pathogen is rare, but when it strikes, it moves fast. People deserve straight talk and simple tools. Warm freshwater up the nose is the route. Keep water out of the nose, especially in hot, shallow lakes.

Share travel and swim history with doctors at the first sign of severe symptoms. These steps respect both freedom to enjoy the outdoors and the duty to protect children.
