Problems solved by technology

[0007] Previous simulation methods have focused on the consistency evaluation of the number of spreaders over time, but if only the consistency of the number of spreaders is required, there are simpler and more effective simulation methods than cellular, which cannot take advantage of the characteristics of cellular simulation of spatial diffusion

Embodiment Construction

[0039] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0040] Such as figure 1 As shown, using an embodiment of the method for simulating the spatial spread of new infectious diseases disclosed in the present invention, firstly, data preprocessing is performed, and a descriptive analysis is carried out on the epidemic situation in city C. Simultaneously, the infection of the first registered household registered in city C in 1995 From 2009 to the end of 2009, more than 6,000 cases of infected persons have been entered into the digitized map according to the location of their residence as spatial information points, and the information of the infected person's gender, age, time of first consultation, occupation, transmission mode, etc. , to establish a geographic information system platform for a certain infectious dis...

Abstract

The invention discloses a novel method for simulating spatial spread of infectious diseases. A geographic information system platform and a cellular automaton are combined to simulate a spatial spread model of the infectious diseases, and the novel method is suitable for multiple infectious diseases including HIV / AIDS viruses and can provide a reference for treating and preventing the infectious diseases.

Description

technical field [0001] The invention relates to the field of medicine, in particular to a method for simulating the spatial spread of novel infectious diseases. Background technique [0002] As a modeling method, cellular automata uses simple evolution rules to simulate complex systems, and its application involves almost every field of social and natural sciences. A cellular automaton is a dynamical system that is discrete in both time and space. Divide a regular grid in a space, the cells are scattered in these grids, and can take a limited number of discrete states, the cells simply interact with neighboring cells through the local rules set in advance, at each time After a step, the state of the cell can change. This process of changing the state of all cells constitutes the dynamic evolution of the entire system. Since the evolution rules of cellular automata are very simple, but they can reflect complex forms, they are often used in the modeling and simulation of co...
