| Outline of Final Research Achievements |
This research attempted to develop an influenza epidemic prediction model in which transmission dynamics is incorporated aiming at improving the operated alert system based on statistical model. Our system is based on coupled SIR model where each component corresponds to each prefecture of Japan. Although the coupled model outperforms a set of independent SIR models in the sense that the confidence interval is narrowed, there is no significant difference in the mean. Therefore I have concluded that the planned approach may not contribute to the improvement of prediction. We also have tried to apply our approach to another disease, rubella, and showed that 2012/13 minor epidemic is reproduced.
