An eight-year-old girl in Louisiana, United States, has died after reportedly contracting a rare and potentially fatal infection caused by Naegleria fowleri, commonly known as the “brain-eating amoeba”, after swimming in a local lake.
The girl, identified as Lillian Smart, fell seriously ill after swimming at Lake Claiborne in northern Louisiana. She was subsequently admitted to a children’s intensive care unit, where doctors battled to save her.
According to reports, health officials and Lillian’s family confirmed that she had contracted Naegleria fowleri, which can cause a severe brain infection known as primary amoebic meningoencephalitis (PAM).
Despite receiving intensive medical treatment, Lillian died in hospital just one day after celebrating her eighth birthday. Her family described the loss as devastating, saying the damage to the young girl’s brain had become too severe despite efforts to save her.
The US Centers for Disease Control and Prevention (CDC) describes PAM as an extremely rare but aggressive infection. The amoeba can enter the body when contaminated water travels through the nose, allowing it to move towards the brain and destroy brain tissue.
Importantly, the infection does not occur from simply swallowing contaminated water. Naegleria fowleri is typically found in warm freshwater environments such as lakes and rivers, while properly disinfected swimming pools and seawater are not considered typical sources.
Health authorities in Louisiana said the state has recorded three deaths linked to the amoeba since 2011. Previous cases have also been associated with exposure to inadequately treated water, including during recreational water activities.
Early symptoms can include headache, fever, nausea and vomiting. As the infection progresses, patients may develop a stiff neck, seizures, confusion and loss of consciousness, with the illness capable of worsening rapidly.
The infection is particularly associated with hot weather, with US cases historically concentrated during July and August. Although extremely rare, the severity of the disease means health officials continue to urge caution when swimming or playing in warm freshwater.
