When floods come, India’s elderly pay the heaviest price
Research links water-related disasters to heightened disease risk among older adults. Yet, disaster planning continues to ignore them.
- India’s ageing population is bearing the brunt of climate‑driven floods and cyclones.
- New research shows adults over 45 years face sharply higher risks of diarrhoea, cholera, typhoid, dengue and malaria after disasters.
- Weakened immunity, chronic illness and poor mobility, combined with ill‑equipped relief camps and weak geriatric planning, leave elders dangerously exposed.
When floodwaters swept through Bihar last monsoon, 68-year-old Ramesh Yadav spent four days wading through contaminated water to reach a relief camp. Within a week, he had developed acute diarrhoea and a skin infection. His story is far from unique.
A new study published in the journal Discover Public Health now provides hard evidence for what communities have long observed: Older adults in India who experience floods and cyclones face significantly elevated risks of contracting waterborne and vector-borne diseases.
The research analysed health data from across India's flood and cyclone-prone regions, examining disease outcomes among adults aged 45 and above. The findings are stark, elderly individuals exposed to water-related disasters showed markedly increased odds of developing diarrhoea, cholera, typhoid, dengue, and malaria in the aftermath.
