A Patch Model for Pandemic Influenza Simulation in Korea

For years, we have researched epidemiology model suitable for Korea based on InfluSim model, to analyze the spread of pandemic influenza. However, there is a problem with InfluSim, because the demographic characteristics and the movement of population within the nation are not considered in the research. For this reason, it is improper to draw preparedness against widespread of pandemic influenza from simulation results based on InfluSim. To overcome this problem, we have designed a patch model considering the nation as 16 separate regions. The patch model takes the 16 separate region's interaction with each other into account. It consists of InfluSim and network model. The network model takes the demographic characteristics and the population flow into account. This paper explains the patch model and also the simulation system based on the model. In addition, we show the result of the simulation based on the patch model.
