Dengue Fever is a human arboviral disease which is transmitted by the domestic mosquito Aedes aegypti and constitutes one of the most widespread tropical diseases around the globe. The only way dengue fever virus can spread is the transmission from human to human via the mosquito. We present a host-vector bipartite network model for the spreading of the Dengue fever epidemics in urban areas. The simulated spatiotemporal system reveals rich dynamical behavior with epidemic thresholds, classes of phase transitions, and synchronization properties. The model is extended to include disease control/immunization strategies and analyzed within the adaptive networks conceptual framework. Validation of the model with field epidemiological data is discussed.
