A fatal case of brain-eating amoeba has been reported in South Carolina, with health officials advising swimmers to take precautions in warm freshwater.

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.

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.
