Delay Induced Hopf Bifurcation of an Epidemic Model with Graded Infection Rates for Internet Worms

A delayed SEIQRS worm propagation model with different infection rates for the exposed computers and the infectious computers is investigated in this paper. The results are given in terms of the local stability and Hopf bifurcation. Sufficient conditions for the local stability and the existence of...
