Naegleria scare

Water sources of one of the most populous cities in the world have long remained vulnerable to contamination by a deadly amoeba, yet authorities have failed to establish a system capable of preventing recurring deaths. The latest fatality caused by Naegleria fowleri, commonly known as the "brain-eating amoeba", is a 44-year-old resident of Korangi who recently lost his life despite having no reported history of swimming or exposure to recreational water. The incident has once again raised questions about the quality of Karachi's water supply, as experts believe the infection was likely contracted through contaminated non-chlorinated tap water.

Naegleria is not an uncontrollable threat. Medical experts have repeatedly emphasised that the amoeba cannot survive in properly treated and adequately chlorinated water. Its continued presence in Karachi's water system points towards a persistent governance failure. The first cases were reported in 2012, when the disease claimed several lives, and the pattern has continued despite repeated warnings. Last year alone, at least five deaths were reported from the city. Yet, the official response has remained largely reactive, with advisories issued after fatalities occur. Public awareness is important, but it cannot become a substitute for state responsibility. Residents cannot be expected to test chlorine levels or determine whether the water supplied to their homes has been properly treated.

The Sindh government and the Karachi Water and Sewerage Corporation must move beyond temporary responses and develop a comprehensive water safety strategy. Chlorination levels should be regularly monitored across the city and independent testing mechanisms should be introduced to ensure accountability. A city cannot claim progress while its people remain vulnerable to a fatal infection from the very water they depend on for daily life.
