我们描述和分析了一些简单的模型接种疫苗的疾病传播的基本手段。特别地,我们给出了多个地方病平衡点和向后分支存在的条件。我们扩展的结果,包括模型中的参数可能取决于感染的水平。(C)2004年爱思唯尔公司All rights reserved.
We describe and analyze by elementary means some simple models for disease transmission with vaccination. In particular, we give conditions for the existence of multiple endemic equilibria and backward bifurcations. We extend the results to include models in which the parameters may depend on the level of infection. (C) 2004 Elsevier Inc. All rights reserved.
