ON A PARTIAL DIFFERENTIAL EQUATION OF EPIDEMIC THEORY. 2. THE MODEL WITH IMMIGRATION
Abstract
A generalization of the basic model which arises in the stochastic theory of epidemics is that for which at time there are in circulation r uninfected susceptibles and s infectives, m + n + a - r - s removals of infectives having occurred since time t = 0. Here the integer m represents the number of susceptible immigrants who have entered the population since time t = 0, when the initial population consisted of n susceptibles and a infectives only. It will be found useful to keep track of the number of immigrants m in the population as well.
