WebWe use an SIR model with the variables s, i and r to represent the fractions of individuals in the total population who are susceptible, infected and recovered respectively [13, 14]. WebSince S + I + R is assumed to be constant, the sum S′ + I′ + R′ of the rates of change of the three subpopulations must be zero – any change in one of these quantities is oﬀset by changes in the others. That is, by the above formulas for S′ and R′, 0 = S ′+I +R′ = −aSI +I′ +bI or, solving for I′, I′ = aSI − bI.
