Emerging and re-emerging infectious diseases of zoonotic origin like highly pathogenic avian influenza pose a significant threat to human and animal health due to their elevated transmissibility identifying the drivers of such viruses is challenging, and estimation of spatial diffusion is . Simultaneously, by applying a general linear model, the predictors that have the strongest impact on viral spatial diffusion were identified, including economic (agricultural) activity, climate, and ecology.

In view of the fact that the spatial diffusion and environmental heterogeneity are important factors in modeling the spread of many diseases, in this paper, we propose an avian–human epidemic model which was described by the following reaction–diffusion equations:. The first essay takes into account spatial and temporal occurrences of hpai h5n1 by using a two-stage procedure: logistic regression modeling followed by bayesian kriging.

With a case fatality rate higher than the 1918 spanish flu pandemic, h5n1 highly pathogenic avian influenza represents a threat to global public health efforts to identify locations with the greatest potential for pandemic emergence, as well as how the virus is spreading, may help minimize this threat. Describe general processes of persistence, emergence and spread of ai through spatial/temporal diffusion analyses, risk assessment and modelling, including: intrinsic data (biological and ecological data on the virus, transmission modes, virulence).
