  We consider a general class of epidemic models obtained by applying a random
time change to a collection of Poisson processes and we show the large
deviation principle for such models. We generalize to a more general situation
the approach followed by Dolgoaschinnykh [3] in the case of the SIR epidemic
model. Thanks to an assumption which is satisfied in many examples, we simplify
the recent work by P. Kratz and E. Pardoux [8].
