We developed and computerized a registration system for information on class suspension caused by influenza infection. By digitizing all items in Form 1, the value of information was improved. The registration system has two main functions. One is to establish registration data for NESID and the other is to use data for GIS. The registration system features not only the data registration function for NESID but also the function to support visualization for GIS. By using ArcGIS made by ESRI, a map of the school district in a Yokohama municipal elementary school was made. By using ‘Yokohamappu’, a map of the number of reported cases per sentinel was made. By using ArcGIS, a map information for class suspension and a chart of the number of reported cases per sentinel were obtained. The visualization of a unitary epidemic state was made possible with this map. We identified the ward where the number of reported cases per sentinel is constantly small. It was found that the information on class suspension in an area does not change with other areas. Thus, the visualization of the number of reported cases per sentinel and information on class suspension provided useful information.
