Compartmental models for influenza that include control by vaccination and antiviral treatment are formulated. Analytic expressions for the basic reproduction number, control reproduction number and the final size of the epidemic are derived for this general class of disease transmission models. Sensitivity and uncertainty analyses of the dependence of the control reproduction number on the parameters of the model give a comparison of the various intervention strategies. Numerical computations of the deterministic models are compared with those of recent stochastic simulation influenza models. Predictions of the deterministic compartmental models are in general agreement with those of the stochastic simulation models.
构建了包含疫苗接种和抗病毒治疗控制的流感 compartmental 模型。针对这类一般的疾病传播模型,推导了基本再生数、控制再生数和疫情最终规模的解析表达式。对控制再生数对模型参数依赖性的敏感性和不确定性分析,比较了各种干预策略。将确定性模型的数值计算结果与近期的随机模拟流感模型的结果进行了比较。确定性 compartmental 模型的预测结果与随机模拟模型的结果总体一致。
