Threshold theorem for an epidemic model

The article discusses a probability model of the spread of an epidemic in which the elimination of sick persons (through death, immunity, or isolation) is taken into account. The authors find a limit distribution for the magnitude of the epidemic,v, on the assumption that n, where n is the original number of susceptible persons, and , where and are the coefficient of infection and the coefficient of elimination, respectively.Translated from Matematicheskie Zametki, Vol. 3, No. 2, pp. 179–185, February, 1968.
