Climate change, marked by extreme weather events like heatwaves and heavy rain, poses a significant health risk through increased exposure to sewage-associated viruses. Continuous heavy rain can overwhelm urban sewer systems, resulting in untreated sewage pollution in rivers, lakes, and coastal waters. Newly researched evidence indicates that such viruses, often found in raw sewage, can linger in the environment, creating potential health threats. While UK wastewater treatments are effective, untreated sewage discharge remains a critical concern for water safety and public health, as it introduces harmful pathogens into the ecosystem.
Raw untreated sewage is released into rivers, lakes and coastal waters due to intense rainstorms, increasing the risk of sewage-associated viruses in the environment.
Climate change may heighten exposure to viruses by overloading urban sewage systems, causing health risks from untreated outfall in lakes, rivers, and coastal waters.
