Recently, a five-year-old girl undergoing treatment for primary amoebic meningoencephalitis (PAM), a rare infection caused by Naegleria fowleri or “brain-eating amoeba”, died at the Government Medical College Hospital in Kozhikode.

About Naegleria fowleri: 

  • It is a free-living amoeba or a single-celled living organism.
  • It lives in warm fresh water and soil around the world, and infects people when it enters the body through the nose.
  • Higher temperatures of up to 115°F (46°C) are conducive to its growth and it can survive for short periods in warm environments.
  • The amoeba can be found in warm freshwater, such as lakes and rivers, swimming pools, splash pads, surf parks, or other recreational venues that are poorly maintained or minimally chlorinated.
  • It enters the body through the nose, usually when people are swimming. It then travels up to the brain, where it destroys the brain tissue and causes swelling.
