Global threat grows as hardy amoebae hitchhike into water systems
Scientists warn that free-living amoebae, some of which resist heat and disinfectants, are spreading globally and can shelter dangerous bacteria and viruses, raising risks for drinking and recreational water. Climate change may push these organisms into new regions, making water management and monitoring harder. The authors call for a One Health approach—strengthening surveillance, diagnostics, and advanced water treatment—to reduce infections before they occur.
