Study on Some Inequalities of a Formula of Population Size due to Epidemics Model Problem

Abstract

In the present chapter, we evaluate a formula of population size due to epidemics model problem for communicable diseases in which the daily contact rate is supposed to be varied with population size N (t) that is large so that it is considered as a continuous variable of time t. Then, we obtain some inequalities of above analytic formula of population size. We present an analysis to discuss the epidemics. These results may also be useful to plot some graphs on population dynamics of the system.
