Within the framework of SIR epidemic model with time-dependent recovery rate the time-behaviour of infectives for cholera and non-choleric diarrhoea has been studied. Here, the population of greater Calcutta has been considered. The infectivity curves for these diseases, as computed from this model, have been fitted with the data available up to 1991 and have been extrapolated up to 2000. The steady number of infectives for the forthcoming year is being predicted here.
