Analysis for nonlinear epidemics among children and prevention strategy based on economical views using by visulalized modeling methods

近年来，风疹作为国家传染病监测的目标传染病之一，国家免疫规划发生了变化。因此，目前的人群通过两种不同的疫苗接种政策进行免疫接种。Suyama等人展示了混合免疫策略的效用。此外，Suyama等人利用国家监测数据进行了一些成本效益分析。两种不同的免疫方案与该分析进行了比较。如果目前的疫苗接种计划完成，国家对风疹感染，特别是先天性风疹综合征的控制可能会成功。与新MMR疫苗接种计划相比，成本效益将为0.5。Takai等人开发了远程控制数据库系统，该系统可通过internet访问。管理人员可以使用该系统识别当前疫情情况。Yonezawa等人还评估了风疹/麻疹流行的非线性现象。他发现了这些流行病的非线性本质，也发现了它们的复杂性，尤其是混沌性。井上等人创建了全球开放的WWW系统，用于分析各国的监测数据系统。Hasegawa等人对这些传染病提出了新的预警指数，并在其机构WWW主页上公布了这些指数。我们的努力使监测服务器易于访问，这对国家疫苗接种规划的决策是非常有益的。

Recently, national immunization program has been changed on Rubella, one of target infectious diseases among national Surveillance for infectious diseases. So, current population are immunized by two different vaccination policy. Suyama et al.showd the utility of mixtured immunological strategy.Furthermore, Suyama et al.performed some cost beneficial analysis using the data of national surveillance. Two different Immunization program were compared with that analysis. If current vaccination program are completed, national control For rubella infection, especially, Congenital Rubella Syndrome, may be successful. That cost beneficial rate versus New MMR vaccination program will be 0.5.Takai et al.developed the remote controlled database system, and that system is internet reachable. Administrative staffs Can identify the current epidemic status using by this system. Yonezawa et al.also evaluate the nonlinear phenomenon of Rubella / Measles epidemics. He found the nonlinear nature in those epidemic and also found the complexity, especially Chaotic nature.Inoue et al.created the wolrd wide opened WWW system for analysis on national surveillance data system.Hasegawa et al.made a new alarming indecies for those infectious diseases and presented those indecies on his Institutional WWW homepage.Our effort of easy access for surveillance server is very useful for decision making for national vaccination program.
