We discuss the epidemic network model with infectious force in latent
and infected period. We obtain the basic reproduction number and analyze the globally dynamic
behaviors of the disease-free equilibrium when the basic reproduction number is less than one.
The effects of various immunization schemes are studied. Finally, the final sizes relation is
derived for the network epidemic model. The derivation depends on an explicit formula for the
basic reproduction number of network of disease transmission models.
