Death of 8-year-old Louisiana girl from rare brain-eating amoeba infection
Consensus Summary
An 8-year-old girl named Lillian Smart died in Louisiana after contracting Naegleria fowleri, a rare and nearly always fatal brain-eating amoeba, likely while swimming in Lake Claiborne. Both sources confirm the infection is extremely rare, with approximately 180 confirmed cases in the US between 1937 and 2025, and thrives in warm freshwater over 77 degrees Fahrenheit. The Guardian notes she died on 19 August, while 7NEWS reports Louisiana had not seen a case since 2013, though The Guardian states only a handful have occurred since 2011. The amoeba’s presence in non-southern states like Maryland, Indiana, and Minnesota has been noted, and experts suggest climate change may be expanding its range.
