The Spread and Risk Analysis of Brucellosis Taking Hinggan League as an Example
摘要
Abstract
Brucellosis In Hinggan League presents characteristics of seasonal human cases and sheep mi-gration,bacteria diffusion between regions.Based on this,a periodic sub-regional paths dynamic sprea-ding model was established.Dynamic characteristic of the model was analyzed,it include the solution of transmission threshold and the proof about global stability of the disease-free periodic solution.Besides, the rationality of the model was confirmed by data fitting about human cases,the positive rate of sheep brucellosis was simultaneously obtained.Finally,with the help of geographic information system (Arc-GIS),risk charts of Hinggan League sheep brucellosis were shown,and precaution and control meas-ures were assessed.The simulation results illustrate that increasing the immunization coverage rate and controlling the sheep transportation between plaques can effectively restrain brucellosis spread.关键词
