What are symptoms and signs of a Naegleria fowleri infection?

After entering the nose, the amoeba travels into the brain along the olfactory nerve and through membranes to enter the brain. Once there, it causes primary amoebic meningoencephalitis (meaning inflammation of the brain and the lining around the brain). In the popular press, Naegleria fowleri is sometimes called the brain-eating amoeba, and meningoencephalitis is sometimes referred to as Naegleriasis.

Symptoms usually appear within five days after exposure but can be delayed up to two weeks. Patients may initially notice changes in smell or taste. Fever, headache, loss of appetite, and nausea follow quickly. The patient becomes confused or semiconscious and finally comatose. Physical examination shows fever and a stiff neck (meningismus).
