Study Warns of Growing Brain-Eating Amoebae Threat
Scientists have warned that brain-eating amoebae, like Naegleria fowleri, are becoming a bigger problem worldwide.
These tiny organisms can survive in high temperatures and even chlorine, making them dangerous in water systems.
They can also carry other harmful germs, spreading infections and antibiotic resistance.
Climate change is making this worse by allowing these amoebae to spread to new areas.
The scientists say we need better ways to monitor and treat water to keep people safe.
They suggest a team effort between health experts, environmental scientists, and water managers to solve this problem.
Brain-eating amoebae are becoming a growing global public health threat due to climate change and ageing water infrastructure.
These amoebae can survive high temperatures, strong disinfectants like chlorine, and live in water distribution systems.
Naegleria fowleri, a notorious species, can cause rare but almost always fatal brain infections when contaminated water enters the nose.
Amoebae act as carriers for other harmful microbes, protecting them from disinfection and helping them spread in drinking water systems.
Scientists call for a coordinated One Health approach, stronger surveillance, improved diagnostic tools, and advanced water treatment technologies to reduce risks.
