性传染病

Firstly, we consider SIQR epidemical models with continuous and pulse vaccinations; the reproduction numbers have been obtained for those models; by using Dulac function, we prove the global stabilities of equilibrium of SIQR model with continuous vaccination. In the SIQR epidemical models with pulse vaccinations, we have also discussed the existence of the infection-free periodic solution, the global stabilities of the infection-free periodic solutions, and the effectiveness of pulse vaccination and continuous vaccination policies has been compared for the two models.

文中首先考虑具有连续免疫接种和脉冲免疫接种的SIQR传染病模型，分别获得了它们各自的基本再生数；利用Dulac函数方法证明了具有连续免疫接种的SIQR模型无病平衡点的全局渐近稳定性；在脉冲免疫接种下SIQR传染病模型里，讨论了无病周期解的存在性，证明了该周期解的全局渐近稳定性，并且对连续和脉冲接种下的SIQR传染病模型的接种效率进行了比较。

There were significant differences of the incidences of 4 water-borne infectious diseases(cholera,hepatitis A,bacteroidal diarrhea and typhoid or paratyphoid)between former 5 years and later 5 years.The incidences of 4 water-borne infectious diseases except bacteroidal diarrhea showed downtrends year after year in 10 past years.By relativity analyzing,there were negative correlations between overall incidences of 4 water-borne infectious diseases and the qualification rate of drinking water coliform group,between the incidence of hepatitis A and drinking water coliform, between the incidence of typhoid or paratyphoid and drinking water total plate countand between the incidence of typhoid or paratyphoid and drinking water coliform.

改水前后各五年霍乱、甲肝、菌痢、伤寒副伤寒等四类主要介水传染病总发病率的差异有显著性，四类主要介水传染病的总发病率与饮用水大肠菌群合格率之间、甲肝发病率与饮用水大肠菌群合格率之间、伤寒副伤寒发病率分别与同期饮用水细菌总数和大肠菌群指标合格率之(来源：A1eBC3737论文网www.abclunwen.com)间呈负相关。
