考虑人口异质性的丙型肝炎模型的构建和动力学分析
Construction and Dynamic Analysis of a Class of Hepatitis C Model with Population Heterogeneity
摘要: 依据丙型肝炎的传播机理,为了研究不同人群传染率系数和急性转变至慢性的比率的异质性因素对丙型肝炎传播的影响,建立了一类具有人口异质性的传染病模型。计算了系统的控制再生数,并对模型进行敏感性分析和数值模拟。研究结果表明:对高危人群增加急性丙型肝炎感染者的筛查和治疗,并且降低两类人群中急性转变至慢性的比例,可以有效地控制丙型肝炎的蔓延。
Abstract: Based on the transmission mechanism of hepatitis C, a class of epidemic model of hepatitis C trans-mission with population heterogeneity is developed in order to study the influnce of heterogeneous factors on the spread of hepatitis C, including the transmission rate in different populations and the conversion ratio from the acute to the chronic. The control reproduction number is calculated, and the sensitivity analysis and numerical simulations are performed. The results indicate that in-creasing screening and treatment of acute hepatitis C infection in high-risk populations and reduc-ing the transition proportion from the acute to the chronic can effectively control the spread of hep-atitis C.
