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).

I have possibly been exposed to aquatic conditions (it has been five days) that could foster infection of Naegleria fowleri, and I have just one of stage 1 symptom being prevalent, i.e., stiff neck, with no current signs of fever, front headache, or nausea.

He was not having any Naegleria fowleri infection related symptoms but was having some flu like symptoms and vomiting. His headache got worse after ten days after his last swimming activity but detecting it early saved his life. He was given a bunch of antibiotics and many sedatives to calm his shouting and beating others because of his intense pain. Please never neglect any symptoms like headache and vomiting after your water related activity, timely diagnosis can save your life for sure!
