项目摘要

The Japanese infectious disease surveillance scheme has been established to detect infectious disease outbreak in early stage, to identify the causative viral strains and to rapidly assess related morbidity and mortality. Based on this schemes, information on infectious diseases are collected from assigned hospitals or clinics and distributed by print or by the Internet. Because the information reported on the home page is usually numerical data or simple graphic chart, it is difficult for medical personnel to grasp the trend of infectious disease morbidity all over the country. We have developed a web-based data visualization system which can automatically generate Flash animations or graphic images and can visualize time series and spatial shifts of case incidents of disease simultaneously.At this time, the information stored in the database system is data related to 47 prefectures in Japan and 21 administrative medical districts on the island of Hokkaido.This system can present the following three kinds of animation or graphic image:1) Flash animation simultaneously showing geographical and progressive changes in morbidity throughout the country.2) A three dimensional bar chart showing annual weekly series rates of occurrence in each prefecture.3) A map chart showing the morbidity of any arbitrary 4 consecutive weeks in Hokkaido.To make the surveillance scheme function well, it is important to provide a good representation of the data collected in compliance with users' requests. It has also been mentioned that two kinds of output are useful for monitoring the morbidity of epidemic disease: time series of incidents of cases and spatial spread of infectious disease incidents. Our system can visualize time series and spatial shifts of the case incidents of disease simultaneously as images or animations on the home page. We believe this makes infectious disease surveillance data more easily comprehensible for medical personnel.

日本传染病监测计划的建立是为了在早期发现传染病暴发，确定致病病毒株，并迅速评估相关发病率和死亡率。根据这一计划，从指定的医院或诊所收集传染病信息，并通过印刷品或互联网分发。由于首页上报的信息通常是数值数据或简单的图表，医务人员很难掌握全国传染病发病的趋势。我们开发了一个基于网络的数据可视化系统，可以自动生成Flash动画或图形图像，可以同时可视化疾病病例的时间序列和空间变化。此时，数据库系统中存储的信息是与日本47个都道府县和北海道岛的21个行政医疗区有关的数据。该系统可以呈现以下三种动画或图形图像：1）同时显示全国发病率的地理和渐进变化的Flash动画。2）显示每个都道府县每周发病率系列的三维条形图。3）显示北海道任意连续4周发病率的地图图。为了使监测方案发挥作用，重要的是根据用户的要求提供良好的数据表示。还有人提到，有两种产出可用于监测流行病发病率：病例事件的时间序列和传染病事件的空间传播。我们的系统可以可视化的时间序列和空间变化的情况下，疾病的事件同时作为图像或动画的主页上。我们相信，这使传染病监测数据更容易为医务人员所理解。
