Abstract: In this
thesis, the relationship between meteorological parameters, water quality and diarrheal
disease is explored. Seasonality assessment showed that the physicochemical water
quality parameters exhibit strong seasonality in both the public and private domains and
the source and household measurements taken on the same day are highly correlated.
Seasonality was not detected for ba... read morecteria concentrations. In the spatiotemporal context,
the results of this study agree with the existing literature that holds that fecal
coliforms tend to increase at the household level if the source water is relatively
clean and vice versa. The direction and magnitude of the change in bacteria
concentrations between the two domains is a potential risk indicator for diarrheal
disease. In terms of the relationship between water quality and disease outcome, risk
ratio, logistic, Poisson and mixed effect models yielded different relationships, which
suggests re-consideration of the epidemiological and statistical approaches taken in the
future aimed at exploring these
relationships.
