On the eve of Onam, the most joyous festival in India's Kerala state, 45-year-old Sobhana lay shivering in the back of an ambulance, drifting into unconsciousness as her family rushed her to a medical college hospital. Just days earlier, the Dalit woman, who earned her living bottling fruit juices in a village in Malappuram district, had merely experienced dizziness and high blood pressure. Despite being prescribed medication, her condition deteriorated sharply, leading to her untimely death on September 5, coinciding with the festival.
The cause of this sudden health crisis was Naegleria fowleri, an exceptionally rare and deadly infection typically contracted through the nose when swimming in contaminated freshwater. There have been over 70 reported cases in Kerala this year alone, with 19 fatalities, affecting individuals spanning from a mere three months old to an elderly 92-year-old.
This single-celled organism inflicts a brain infection known as primary amoebic meningoencephalitis (PAM), usually resulting in death due to its rapid and destructive nature on brain tissues. The state has noted an increase in these infections since 2016, but the majority were significantly fatal until recent improvements in detection and treatment.
In Kerala, cases of Naegleria fowleri began appearing with alarming regularity, with this year's data revealing nearly 70 diagnosed cases and a climbing fatality percentage at 24.5%. Experts attribute this uptick to advanced diagnostic capabilities and intensified awareness initiatives regarding symptoms and prompt treatment.
The rise of these infections can be partly linked to climate change, which has enhanced the warm conditions necessary for the amoeba's survival and growth. Additionally, Kerala's significant dependence on groundwater, coupled with pollution issues in natural bodies of water, presents a heightened risk for residents who often utilize untreated water for various purposes, including recreational swimming.
Local health authorities have taken measures to mitigate risks, including the chlorination of 2.7 million wells and prohibition signs around potentially dangerous ponds; however, sustaining these efforts presents considerable challenges. Public education remains essential, urging clear measures such as avoiding untreated freshwater, using clean water for nasal rinsing, and protecting oneself while swimming.
Despite increased detection and treatment, the tragic loss of lives emphasizes the ongoing threat posed by Naegleria fowleri and allows broader reflections on the intersection of climate change and rising health risks. Scientists warn that the factors driving this amoeba's spread could mean that even rare diseases will become more common, challenging healthcare systems worldwide.
