具有两羊群间运输的布鲁氏菌病模型分析
Analysis of a Brucellosis Model with Transportation Between Two Flocks
摘要
Abstract
This paper proposes a multi-group susceptible-exposed-infected-vaccinated(SEIVW)dynamic model with transportation between two flocks considering environmental factors,in order to propose a multi-group SEIVW dynamical model with two flocks'transport.Firstly,the basic reproduction number R0 is obtained,and the global dynamics are completely determined by R0.When R0<1,the disease-free equilibrium is globally asymptotically stable;when R0>1,there is a unique local equilibrium that is globally as-ymptotically stable.The sensitivity analysis of the parameters of the basic reproduction number is carried out and confirmed that timely removal of the bodies of infected sheep and increasing vaccine coverage were effective control strategies for sheep brucello-sis.In addition,reasonably reducing the transportation between flocks and achieving self-sufficiency of flocks is another effective control strategy for controlling brucellosis.关键词
