Twelve-year-old Jaysen Carr was full of life until a summer day at Lake Murray, South Carolina, changed everything. Days after enjoying the water with his family, he developed symptoms that quickly escalated. Within a week, he was dead.Doctors confirmed the reason as Naegleria fowleri, a rare and aggressive organism infamously dubbed the “brain-eating amoeba.” The South Carolina Department of Public Health and Prisma Health Richland Hospital in Columbia reported the pediatric death publicly on July 22. It's the first such case in the state since 2016.The microscopic killer that claimed Jaysen’s life is a naturally occurring amoeba found in warm freshwater. It causes a deadly brain infection called primary amebic meningoencephalitis (PAM), which destroys brain tissue and is almost always fatal.The Carr family, devastated by their sudden loss, is now seeking answers. Their attorney, Tyler Bailey, stated that while the family appreciates the outpouring of support from their community and the care provided by Prisma Health, they are committed to ensuring such a tragedy doesn't happen to another family."They have many questions about how and why Jaysen died," Bailey said in a public statement. “And they want to do everything in their power to make sure this doesn’t happen again.”What Is a Brain-Eating Amoeba?Naegleria fowleri is not actually “eating” your brain the way a parasite might devour tissue. But what it does is arguably worse. Once it enters the body—usually through the nose—it migrates to the brain, where it rapidly causes inflammation, swelling, and destruction of brain tissue.This isn’t something you can catch from drinking water or shaking someone’s hand. It’s not contagious. You have to get water up your nose—typically during activities like swimming or diving in warm, untreated freshwater.How Common Is Brain-Eating Amoeba?That’s the strange part, for all its horror, Naegleria fowleri is incredibly rare.According to the CDC, only 167 cases have been reported in the U.S. over the last six decades. And of those, only four people have survived.Despite this rarity, every summer it resurfaces in headlines because it tends to thrive in the very water bodies people flock to when temperatures rise—lakes, rivers, ponds, and hot springs, especially in Southern and Southwestern states like Texas and Florida.In Jaysen’s case, the suspected exposure was Lake Murray, although health officials clarified that since the amoeba occurs naturally in many bodies of freshwater, pinpointing the exact source isn’t always possible.What Causes Brain-Eating Amoeba?Naegleria fowleri typically infects people when contaminated water enters the nose. Once inside, the amoeba travels along the olfactory nerve into the brain. That’s when things go downhill.Initial symptoms appear within one to twelve days and may resemble meningitis or flu: headache, fever, nausea, vomiting, stiff neck. But very quickly, the infection escalates to confusion, seizures, hallucinations, coma—and then death. Death usually occurs within 5 to 10 days after symptoms begin.Where Does Brain Eating Amoeba Come From?Naegleria fowleri loves heat. It survives in water up to 115°F (46°C), which means late summer is prime time for activity. It’s found in:Warm lakes, ponds, and reservoirsHot springs and geothermal watersSlow-flowing warm riversMud puddles and untreated wellsPoorly maintained swimming pools or water parksUntreated municipal water supplies in rare casesIt cannot survive in saltwater, nor in properly chlorinated pools. And again, you can’t get infected by drinking contaminated water—only if it goes up your nose.How To Avoid Brain-Eating Amoeba?There is no vaccine or guaranteed treatment for Naegleria fowleri. So prevention is the best—and only—defense. Here’s what health experts suggest:Avoid freshwater activities, especially in warm, still water during the summer.Hold your nose or use nose clips when swimming or diving in lakes and rivers.Avoid stirring up sediment where the amoeba may live.Stay away from untreated splash pads and recreational water parks with unclear sanitation practices.Never use tap water to rinse your sinuses or fill neti pots unless it’s been properly boiled, distilled, or filtered with a 1-micron filter.Even if risk is low, it’s not zero—especially when the result of infection is nearly always fatal.Why Is Brain-Eating Amoeba So Hard to Treat?Once symptoms begin, treatment options are limited. The infection progresses too rapidly for most medications to have an effect. Some experimental treatments using antifungal drugs and hypothermia (lowering body temperature to reduce inflammation) have been used in a few survivors. But survival still depends heavily on early diagnosis, which is challenging because early symptoms mimic other common illnesses.Has There Been Any Survivor Of Brain Eating Amoeba?In 2024, 14-year-old Afnan Jasim from Kerala, India, stunned doctors by surviving PAM. His case was one of the very few globally where the infection was caught early enough, and an aggressive combination of treatments including antifungal and antibacterial medications, supportive care, and cooling therapies—was able to halt the amoeba’s advance.Health officials urge calm and reiterate that the risk to the general public is extremely low but for parents, educators, and communities especially those in warmer regions—it’s a time to pay attention.
