Study on Spread Model of Infectious Diseases

This article establishes exponential model according to data provided by the data base and comprehensively evaluates the rationality and practicality of this model. Then conduct a more comprehensive assessment of the issue, based on the introduction of a more comprehensive and reasonable assumptions and establishes analysis model system. Use set of simultaneous differential equations to reflect the epidemic development process inherent causal link between various types of people, and on this basis, this paper establishes the equation solving algorithm with MATLAB Programming (Annex II program) and gets an actual fitted curve and makes the epidemic prediction. The modeling process personal experience illustrates the importance of the establishment of infectious diseases such as SARS forecast model prediction models.
