Unseen Threat: Brain-Eating Amoeba Confirmed in Kozhikode Well After Tragic Death

A chilling discovery has sent ripples of concern across Kerala, as health officials confirm the presence of the deadly 'brain-eating amoeba,' Naegleria fowleri, in a well in Kozhikode. This alarming finding comes in the wake of the tragic death of a 15-year-old girl, Fathima, from Perambra, who succumbed to Primary Amoebic Meningoencephalitis (PAM), a rare and often fatal infection caused by this microscopic organism.

The State Health Department initiated immediate investigations after Fathima's demise, with samples collected from the well she regularly used for bathing and daily chores.

Laboratory tests have now conclusively identified Naegleria fowleri in the water, directly linking it to the source of the fatal infection. This confirmation has prompted intensified surveillance and awareness campaigns in the region, particularly around Perambra.

Naegleria fowleri is a single-celled organism typically found in warm freshwater bodies such as lakes, rivers, ponds, and untreated swimming pools.

It is infamously dubbed the 'brain-eating amoeba' due to its devastating impact once it enters the human body. Infection occurs when contaminated water enters the nose, usually during activities like swimming, diving, or even washing. From the nasal passages, the amoeba travels to the brain, causing severe inflammation and destruction of brain tissue, leading to PAM.

Symptoms of PAM typically appear within one to nine days after exposure and include severe headache, fever, nausea, vomiting, stiff neck, confusion, lack of attention to people and surroundings, seizures, and hallucinations.

The progression of the disease is rapid and, tragically, the mortality rate is exceptionally high, exceeding 97%. Early diagnosis is crucial, but due to its rarity and non-specific initial symptoms, it is often missed until it's too late.

In response to the current situation and previous isolated cases reported in Kerala (including earlier instances in Alappuzha and Thrissur), the Health Department has issued strict guidelines and advisories to the public.

Residents are strongly urged to avoid bathing or swimming in stagnant freshwater bodies, especially during warmer months when the amoeba thrives. It is recommended to use only chlorinated water for bathing and cleaning purposes. Households relying on well water are advised to ensure proper chlorination and regular cleaning of water storage tanks.

Authorities are actively monitoring water sources in the affected and surrounding areas, conducting extensive testing, and educating the community on preventative measures.

While the risk of infection remains low, the potential severity of PAM underscores the importance of adhering to health advisories and maintaining vigilance regarding water safety. The tragic loss in Kozhikode serves as a grim reminder of the hidden dangers that can lurk in seemingly innocuous natural environments.
