Although infections remain extremely rare, the "brain-eating amoeba” known as Naegleria fowleri is highly dangerous. According to the CDC, only four people survived out of 167 reported US cases between 1962 and 2024. Infection occurs when contaminated water enters the nose, often while swimming or diving in lakes, rivers, or hot springs.
Sadly, two children in different parts of the US died of Primary Amoebic Meningoencephalitis (PAM), the illness caused by Naegleria fowleri, in August 2026. Scientists warn the organism has been steadily spreading northward as global temperatures rise, prompting calls for stronger monitoring and public awareness campaigns.
In light of these tragedies, understanding the risks of Naegleria fowleri is becoming increasingly important. Click through this informative gallery to learn more about the deadly amoeba, its symptoms, and how to stay safe.
