Climate change could undermine progress in reducing waterborne diseases, study finds
A study published in Nature Reviews Microbiology warns that climate change is altering environmental conditions, potentially accelerating the spread of waterborne diseases. Researchers emphasize that public health strategies must adapt to how different pathogens respond to changing temperatures and weather patterns.
Why it matters
Understanding the link between climate change and disease transmission is critical for global public health planning and infrastructure development.
More frequent extreme weather events, driven by climate change, could undermine decades of the world's progress in reducing waterborne diseases, a review has found.
Waterborne diseases are a major cause of mortality and morbidity, especially in low and middle-income countries and among children aged under five.
Climate change does not affect all disease-causing microorganisms -- or pathogens -- the same way; it is altering the environmental conditions that determine whether pathogens survive, spread and infect new hosts, showed findings published in the journal Nature Reviews Microbiology.
Researchers -- led by those at the University of Colorado Anschutz and the University of Washington in the US -- said that climate change is thus modifying the spread of waterborne diseases around the world.
Therefore, public health response should be tailored to specific pathogens, as bacteria, viruses and parasites each respond differently to changing environmental conditions, they said.
