Background: Access to safe drinking water has long been a central aim of public health. In
Objectives: To assess the sanitary conditions of household drinking water sources, and hygienic practices of community and the incidence of water borne disease. To find out the relation of water borne disease with the former two parameters.
Methodology: A longitudinal study was conducted in the Kerala state of
Results: During the 12 month follow up period 72 episodes of water borne disease were reported with an incidence rate of 49/1000 person years. Dug wells were the major household water sources (93.3%)and up to 30% water sources contain indicator bacteria Escherichia coli ,and more than 60% water sources contain Fecal coli from >10MPN/100 ml in all the seasons. Stagnant water at their premises was found to be associated with WBD (RR=3.58, 95% CI 1.90 -6.73, P=0.01) and proximity within 15meters from the septic tanks was found to be associated with increased incidence of WBD (RR=2.2, 95%CI 1.00- 4.63, P=0.04).
Conclusion: Our study found that improved water sources are not free from bacteriological contamination. The structures which included in the criteria for a sanitary well may not always protect the consumers from the risks of WBD.
