I am trying to find a good reference to double check this, but I believe that N should remain constant.
From the technical point of view, the derivation of the model requieres N constant. In the simplest model, one has (S/N)' = - \beta (I/N)(S/N), representing that contacts are independent and \beta is the infection probability in a given contact. This equation becomes S' = - \beta/N I S iff N is constant.
From the practical point of view, if the reduction in N is significant, the effective population in the camp is small and the SEIR type model is no longer be a good approximation.
Clarify if N should be reduced with deaths and removal of population from the camps
