| 摘 要： | 通过建立吸毒人群中交往关系(包括针具共用和性关系)的"危险关系网络",我们研究了一个关于HIV在此人群中传播的随机模型,得到了基本再生数和最终感染者比例。使用四川省西昌市的调查数据,我们研究了针具共用以及性关系的网络规模对模型最终结果的影响。模拟发现,每个注射吸毒者每增加一个"三人小圈子"网络,将最终导致增加10%的感染者。结果提示:减少危险关系网络的规模,尤其是针具共用的网络规模,对控制HIV的传播有重要的作用。

| Abstract: | Using a risk network to describe the contact patterns(including needle sharing and sex behavior) of buddy relationships in injecting drug users(IDUs),a stochastic model is studied about the spreading of HIV-1 in IDUs.The basic reproduction number and the final size of the epidemic are obtained.In particular,the model has been applied to Xichang city.Through simulations,the effect of the injecting network size(and also the sex network size) in the spreading of HIV-1 in IDUs are studied.The model shows that 1... |
