Equal numbers of age and sex matched controls were enrolled from the neighborhood. Descriptive statistics, univariate and multivariate analysis was done. Qualitative assessment of the environment was also done. Results: A total of 98 cases were identified in which 66% (n= 65) were female. Mean age was 32 years (12-65 years). Age group 21-30 years (n= 32, 32.7%) were the most affected group. Drinking water from the storage tanks (OR=16.6), living in the same house (OR=20.28) were associated with illness. Six water samples were tested and found unfit for human consumption. Multiple logistic regression shows association of household size (>5 person in room of house) (OR 7.46), typhoid patients handling and cooking food (OR=13.43) and drinking water from storage tank (OR 12.62) with disease. Conclusion: Contamination of drinking water sources with human fecal matter was the most probable cause of this outbreak. Awareness campaign was initiated.
