Diarrhoeal disease forms one of the two major killer diseases in children under five years of age in the developing world. Data on the prevalence and related factors of diarrhea in Kashmir valley is quite scanty. Thus this study was carried out to find the burden of diarrhoeal disease and the effect of a temperate climate (as compared to a tropical one in rest of India) on the pattern of diarrhoeal disease in Kashmir valley. Cross sectional study was carried out using pretested interview schedule. Overall period (last 15 days) and point (24 hrs) prevalence rates of diarrhoeal diseases among children under age of 5 years were calculated which came to the order of (25.2%) and (9.3%) respectively. Prevalence of diarrhoea decreased significantly with increased age and in summer months. The burden of diarrhoeal disease in Kashmir is quite high, like most places in the developing world. The age pattern, and seasonal pattern of diarrhoeal disease also resembles that found in studies across India and the developing world.
