Nationwide, there have only been 167 cases of Naegleria fowleri in the past 62 years — but only four of those survived, according to the CDC.

A patient at Prisma Health Children's Hospital Midlands in South Carolina died after being infected with Naegleria fowleri, a brain-eating amoeba, Dr. Anna Kathryn Burch, a pediatric infectious disease specialist, said during a press conference on July 22.

Jaysen Carr, a 12-year-old from the city of Columbia, died on July 18 after developing an infection associated with Naegleria fowleri in Lake Murray, according to a statement released by the family’s attorney.
