Epidemic situation prediction and prevention concern national defense and people's livelihood. How to control and prevent typical infectious diseases globally is an important subject for scientific researchers. As a zoonosis, brucellosis as well as its prevalence and transmission range cannot be made light of. Epidemiological characteristics of the disease are modeled precisely in this paper. Through the integration of infection sources and infection routes, the author expands the dimension of infection sources and gives comprehensive description and explanation on the probability of human and animal illness. The strategy of deep learning is applied in the regression analysis based on the classical theory of statistics. Accuracy and robustness of the model are improved through the self-learning of the deep learning algorithm on the regression model and regression parameters. This paper provides a reliable theoretical support and planning guide for epidemic prevention and control policies.
