The amoeba enters your body through the nose. Here, it enters to your brain.
Symptoms of brain-eating amoeba infection include fever, nausea, vomiting, and stiff neck.
Naegleria fowleri lives in warm freshwater including rivers, hot springs and lakes.
There is no specific treatment for the infection, but aggressive supportive care can improve the chances of survival.
