The infection occurs when the amoeba known as Naegleria fowleri gets into your brain through your nasal cavity. It can enter your body if you inhale any infected water. Usually, the amoeba lives in freshwater bodies of water that are warm, including hot springs (geothermal water). You can also be infected by inhaling infected dust. There have been other cases of reported infection by brain-eating amoeba (Naegleria fowleri) due to people using tap water rather than distilled or sterilized water to rinse out their noses with devices like a neti pot.
