Impact of climate change on diarrhoea risk in low- and middle-income countries

Diarrhoea remains a leading cause of mortality among children under five years of age, with over 99 % of deaths occurring in low- and middle-income countries. Poor water quality, inadequate sanitation, poverty, undernutrition, and limited healthcare access contribute to this lingering problem, together with emerging environmental stressors driven by climate change.

Abstract:
Diarrhoea remains a leading cause of mortality among children under five years of age, with over 99 % of deaths occurring in low- and middle-income countries. Poor water quality, inadequate sanitation, poverty, undernutrition, and limited healthcare access contribute to this lingering problem, together with emerging environmental stressors driven by climate change.
