What is Primary Amoebic Meningoencephalitis mean?
Naegleriasis (also known as primary amoebic meningoencephalitis; PAM) is an almost invariably fatal infection of the brain by the free-living unicellular eukaryote Naegleria fowleri. Symptoms are meningitis-like and include headache, fever, nausea, vomiting, a stiff neck, confusion, hallucinations and seizures. Symptoms progress rapidly over around five days, and death usually results within one to two weeks of symptoms.
N. fowleri is typically found in warm bodies of fresh water, such as ponds, lakes, rivers and hot springs. It is also found in an amoeboid or temporary flagellate stage in soil, poorly maintained municipal water supplies, water heaters, near warm-water discharges of industrial plants and in poorly chlorinated or unchlorinated swimming pools. There is no evidence of it living in salt water. As the disease is rare, it is often not considered during diagnosis.
Although infection occurs very rarely, it almost inevitably results in death. Of the 450 or so naegleriasis cases in the past 60 years, only seven have survived, for a case fatality rate of 98.5%.
