A note on the ultimate size of a general stochastic epidemic
University of Birmingham
A relation between the probability that an epidemic in a population of size
ends with X sueceptibles remaining uninfected, and the probability that a different epidemic in a population of size
a ends with Xa uninfected susceptibles is proved by a probabilistic argument. This relation, due to Daniels (1966). is then used to obtain a formal expression for these probabilities without recourse to the usual backward or forward equations.
