Panic In Kerala As Brain-Eating Amoeba Claims 5 Lives In A Month, 11 Under Watch

Kerala, an Indian state located in the south and famous for its backwaters and green scenery, is now in the midst of increasing fear. Five individuals—children as young as three months old—have died in the last month alone due to a rare but deadly infection referred to as amoebic meningoencephalitis. The infection, brought on by "brain-eating" amoebae present in tainted water, has shocked the region and attracted worldwide attention to the dangers represented by emerging pathogens.The newest victim, 56-year-old Malappuram district resident Shobhana, died on September 9 while receiving critical care at Kozhikode Medical College Hospital (MCH). Only a few days ago, another patient, Ratheesh, from Sulthan Bathery had passed away. Three others—a three-month-old infant, a nine-year-old girl, and a 52-year-old woman—also perished in the recent weeks. At least 11 other patients, including children, are still under observation at the state's biggest tertiary care center.Why This Infection is So Lethal?The perpetrator is neither a virus nor a bacterium, but free-living amoebae like Naegleria fowleri, Acanthamoeba, and Balamuthia mandrillaris. These are microscopic organisms that live in hot, stagnant freshwater and inadequately maintained sources like rivers, ponds, and untreated wells. The disease occurs in two forms:Primary Amoebic Meningoencephalitis (PAM): Due to Naegleria fowleri, commonly referred to as the "brain-eating amoeba." It enters via the nose, migrates along the olfactory nerve, and directly infects brain tissue. Symptoms—headache, fever, nausea, stiff neck, seizures—rise within days, frequently terminating in death.Granulomatous Amoebic Encephalitis (GAE): Due to Acanthamoeba and Balamuthia, these infections spread more slowly, reaching the brain via blood through inhalation or skin injury.Worldwide, amoebic meningoencephalitis has a case fatality of as much as 97 percent. Infections were rare, having been first reported by India in 1971. But in the past two years, Kerala has witnessed a surge: 36 confirmed cases and nine deaths in 2023 alone, a sharp contrast to eight in the six years that had transpired.What concerns professionals is not only the increasing figures but also systemic failures. Kerala's public health activists mention lack of coordination between state authorities, local health bodies, and hospitals. There is no unified database available that records confirmed cases, recoveries, or deaths, making health workers and the population oblivious.Drugs essential in the treatment of patients are not produced locally and have to be imported, in most cases resulting in delays in treatment. Kozhikode MCH officials confirmed that drugs for specialty have been ordered from overseas, but medical practitioners assure that prognosis is still bleak, particularly among patients with comorbid conditions.Has Climate Change and Environmental Factors Increases Risk Of Infection?Why is Kerala seeing such an upsurge now? Scientists and doctors think that climate change could be responsible. Temperature increases and unpredictable rainfall patterns are leading to more stagnant water bodies where amoebae can grow.Dr. Abdul Rauf, a pediatric intensivist from Baby Memorial Hospital at Kozhikode, says that most recent cases have had delayed onset of symptoms—sometimes two weeks—are indicative of other amoebae like Acanthamoeba or Balamuthia as the causative agents. He further states that dirty water with high coliform content, associated with sewage and poor drainage, also raises chances of infection.This brings into question larger environmental issues. With fast development, poorly designed drainage systems, and houses located near waste disposal grounds, citizens are being subjected to situations that could trigger the spread of unusual pathogens.Fear and Changing HabitsIn northern Kerala—specifically Malappuram, Kozhikode, and Wayanad districts—people are going out of their way to shun ponds and rivers. Parents don't want to let children swim, and villages have gone so far as to declare temporary prohibitions against bathing in communal water bodies. The fear is palpable: each new case contributes to a sense of vulnerability, given how low the survival rates are.Kerala notched up its very first survivor of PAM in July 2024—a boy of 14 from Kozhikode who became one of only 10 known survivors globally. Although that was celebrated as a rare triumph, it highlighted how slim the chances of survival are.While amoebic meningoencephalitis is uncommon, Kerala's outbreak highlights a global reality: climate-sensitive diseases once relegated to "medical curiosities" are no longer only found in textbooks. With freshwater sources heating up and sanitation infrastructure coming under strain, more communities around the world may be vulnerable.For public health officials, the Kerala crisis is a reminder that rapid response, early detection, and open data-sharing are not choices—the choice is lifesaving. For residents, it's a stern call to re-think common interactions with natural water sources.Kerala's health department has now launched special treatment protocols, pressed local governments to keep a watchful eye on water quality, and stepped up awareness campaigns. Experts caution, however, that these steps need to go beyond firefighting. Long-term investment in sanitation, drainage, and access to clean water will be critical.Worldwide, experts emphasize the immediate need for stronger surveillance and increased investment in treatment for free-living amoeba infections. Treatments available today are restricted and in some cases, experimental. A more powerful drug pipeline, in addition to prevention with measures such as chlorination of water supplies and improved environmental sanitation, may decrease mortality.
