Based on the related knowledge of the ordinary differential equations and mathematical modeling, the cross-infection disease models with two species are formulated by application differential method. We also obtain some conclusions by analyze and study the cross-infection disease models.
The whole paper is consisted of three parts: The first chapter introduces the background and research status of the infectious disease model. The second chapter describes some tradition of classical epidemic models. The third chapter set up six new infectious diseases, is a key part of the paper.
