Kerala: What is 'brain-eating amoeba'? Check causes, symptoms, treatment

A 14-year-old teen succumbed to amoebic meningoencephalitis infection in Kerala on July 3. 

According to health officials, this is the third fatality of "brain-eating amoeba" in Kerala in the last two months.

Also known as "brain-eating amoeba", Naegleria fowleri is a rare and fatal microorganism that causes severe brain infection known as primary amoebic meningoencephalitis (PAM).

This amoeba can damage the brain tissue and typically takes two to 15 days to spread. The symptoms progress rapidly after exposure. 

PAM diagnosis can be difficult in early stages as the symptoms closely resemble those of bacterial or viral meningitis.

Early-stage symptoms of Naegleria fowleri infection include severe headache, high fever, stiff neck, nausea and/or vomiting.

In the later stages, the patient can become disoriented, and confused, suffer from seizures, lose balance, and may go into a coma. This infection is mostly fatal.

According to the USA's Centres for Disease Control and Prevention, Naegleria fowleri amoeba thrives in warm freshwater lakes, rivers, hot springs, and even poorly-maintained swimming pools.

This amoebic infection can occur when the amoeba enters the body through the olfactory nerve, located near the nasal cavity. Swallowing this amoeba does not lead to infection.

According to the Cleveland Clinic, PAM is not contagious as there have been no cases of transmission. 

97 percent of the PAM cases are fatal as it is difficult to diagnose and it progresses quickly. However, according to the CDC, some survivors in North America have been treated.
