Two weeks after spending the Fourth of July on a popular South Carolina lake, 12-year-old Jaysen Carr died from a brain-eating amoeba that was living in the warm water.

COLUMBIA, S.C. (AP) — A 12-year-old boy died from a brain-eating amoeba two weeks after a holiday weekend on a popular South Carolina lake. The brain-eating amoeba enters the body when water is forced up the nose, like when someone jumps or dives in the water.

A child in South Carolina has died after being infected with Naegleria fowleri, commonly referred to as brain-eating amoeba. State health officials confirm exposure likely came from Lake Murray the week of July 7.
