A new study warns that climate change could reverse decades of progress in reducing waterborne diseases. Rising temperatures, floods, droughts, and other extreme weather events are creating conditions that allow harmful pathogens to spread more easily, increasing the risk of infections worldwide.
Different Pathogens, Different Risks
As per The Economic Times, climate change affects bacteria, viruses, and parasites in different ways. While warmer temperatures encourage the growth of bacterial pathogens, droughts can concentrate microbes in limited water sources, and floods can contaminate drinking water supplies.
Stronger Public Health Measures Needed
Therefore, researchers recommend pathogen-specific disease surveillance instead of a one-size-fits-all approach. They also urge governments to invest in climate-resilient water, sanitation, and hygiene (WASH) infrastructure while expanding vaccination programmes to reduce future outbreaks.
Call for Climate-Ready Solutions
Overall, experts stress that adapting public health systems to changing climate conditions is essential to protect communities and prevent a rise in waterborne diseases in the years ahead.
