Abstract
We consider a multitype epidemic model which is a natural exten- sion of the randomised Reed-Frost epidemic model. The main result is the derivation of an asympotic Gaussian limit theorem for the flnal size of the epidemic. The method of proof is simpler, and more direct, than is used for similar results elsewhere in the epidemics literature. In particular, the results are specialised to epidemics upon extensions of the Bernoulli random graph.
