Improving SIR model of infectious diseases by calculating at shorter time intervals

Abstract

In this paper concepts related to SIR model of infectious diseases, the Mathematical model used to explain factors of the diseases vividly, and their transmission dynamics were dealt in depth. Studying the transmission dynamics of infectious diseases by making use of mathematical terms-variables was employed at different time intervals and calculations from a given set of data were carried out forward and backward in order to check the differences that may occur due to the rate differences in the time interval of the calculations. Finally, it was found out that discrepancies in the calculations got smaller and smaller when shorter time intervals were used, which in turn is meant SIR model of infectious diseases can be improved if relatively less time intervals are used in one’s calculations.
