What you must know about Amoebic Meningoencephalitis?

Amoebic meningoencephalitis or primary amoebic meningoencephalitis or PAM, also called naegleriasis is a rarely found and almost always fatal brain and spinal cord disease that is caused by a free-living amoeba, Naegleria fowleri. 

Infection occurs when water containing the amoeba enters the body through the nose that is usually during swimming, bathing, or diving into warm freshwater in lakes, hot springs or rivers.

After the amoeba is introduced into the body, it moves into the brain and causes extreme inflammation, and damage to brain tissue.

Symptoms and Progression

The disease usually develops within 1 – 12 days of exposure and starts with the following symptoms:

Headache

Fever

Nausea and vomiting

Stiff neck

Alteration in taste or smell

Since the infection spreads very quickly, patients become confused, develop hallucinations, experience seizures, loss of balance, and coma. Death typically happens within a period of one to two weeks from the onset of symptoms.

High Mortality Rate

Amoebic meningoencephalitis is very rare but nearly always fatal, with more than 90% mortality even with treatment. Throughout the world, only a few patients have survived following diagnosis.

This is the fourth reported case of amoebic encephalitis in Kozhikode district in 2025, revealing an immediate public health issue. Specialists warn against swimming or bathing in stagnant or unchlorinated freshwater bodies, particularly during summer and monsoon, when amoeba proliferation tends to occur more readily.
