Abstract: Based on the study of the transmission mechanism of echinococcosis and the epidemic situation of echinococcosis in Tibet, a multiple time-delays echinococcosis transmission model with media effect is established. The stability of the model, uniform persistence and the conditions of Hopf bifurcation are studied and numerical simulation is performed on the data from Tibet, to verify the significance of the media effect on disease control and the influence of time lag on the stability of the model. Finally, reasonable suggestions are given for the prevention and control.

Key words: echinococcosis, dynamic model, multiple delays, Hopf bifurcation
