Kerala has reported at least 18 active cases of amoebic meningoencephalitis, a rare and deadly brain infection caused by the “brain-eating amoeba” Naegleria fowleri. This brings the total number of cases in the state this year to 41. Tragically, a nine-year-old girl from Kozhikode’s Thamarassery lost her life after being infected.
While the infection is extremely rare, its death rate is alarmingly high, with medical experts estimating over 97% fatality even when treatment begins. This should concern not just Kerala but the entire country, as climate change, poor water management, and lack of awareness could make more people vulnerable.
This is not just a health story—it is a wake-up call about how we deal with water safety, public awareness, and healthcare readiness.
The culprit, Naegleria fowleri, is a free-living organism that thrives in warm and shallow freshwater—lakes, rivers, ponds, and even poorly maintained swimming pools. It does not need a human host to survive, but when it enters the nose while swimming, diving, or cleaning nasal passages with contaminated water, it travels to the brain.
Once inside, it causes amoebic meningoencephalitis, a rapid infection of the central nervous system. The symptoms—fever, severe headache, nausea, vomiting, stiff neck, light sensitivity, confusion, seizures, and eventually coma—are frighteningly similar to meningitis, which is why diagnosis is often delayed. By the time doctors confirm the cause, it is usually too late.
The case in Kozhikode is not an isolated tragedy. The infection has spread across multiple districts, including Thiruvananthapuram, Kollam, Wayanad, and Malappuram. These are not just numbers; they are families losing loved ones, children’s lives cut short, and communities living in fear of something they had never even heard of before.
So the question arises—why do we only react after tragedy strikes?
The hard truth is that science has not yet found a reliable treatment for Naegleria fowleri. Medicines exist, but success stories are extremely rare. That means prevention is not just important—it is the only real defense we have.
Public health agencies and experts have made it clear that avoiding risky exposure is the most effective protection. This means:
Avoiding swimming or water sports in warm, stagnant freshwater without proper nose protection.
Never using tap water in neti pots or nasal rinses unless it has been boiled, filtered, or sterilized.
Chlorination and proper disinfection of water supplies to reduce the amoeba’s chances of survival.
Spreading awareness in schools, community centers, and local health campaigns so that people recognize symptoms early and seek immediate medical care.
But here’s where the government and society must step up. Kerala, known for its strong public health model, must expand its campaigns beyond cities to rural areas, where children often swim in ponds and rivers. Hospitals must be equipped with better diagnostic tools, because early detection is the only way survival is even remotely possible.
At the same time, we as individuals must take responsibility. How many of us boil water before using it in nasal cleaning? How many parents know the risks of letting children swim in warm ponds during the summer? Awareness should not be a luxury available only to the educated—it must reach every household.
Kerala’s situation is a warning for the rest of India. As temperatures rise due to climate change, warm freshwater bodies could become even more favorable for Naegleria fowleri. States must act now to monitor water sources, educate people, and build healthcare readiness.
We cannot afford to dismiss these cases as “rare” and wait for the numbers to rise. The COVID-19 pandemic should have already taught us the price of underestimating unseen threats.

The brain-eating amoeba is not just a medical problem—it is a test of how seriously we take public health, education, and preventive care. If a tiny organism can defeat modern medicine with such ease, then surely our best weapon is knowledge and awareness.
Kerala’s tragedy must turn into India’s lesson: Prevention today is better than grief tomorrow.
