Objectives: Establish and review enhanced surveillance for the G20 Summit in Osaka that allows all Osaka municipalities to share information on infectious disease events that could affect the Summit or could result from the Summit.
Methods: We selected 19 infectious diseases that could affect or result from the G20 Summit, and then we enhanced routine surveillance with supplemental surveillance in order to facilitate detection of those diseases during the Summit period (10 June – 16 July, 2019). To centralize data collection, we temporarily established the G20 Infectious Disease Information Analysis Center. Members of the Analysis Center assessed surveillance data and distributed feedback reports daily. The feedback reports included an overview of each surveillance system's data and results of the daily risk assessment. To evaluate this enhanced surveillance system, we surveyed stakeholders by questionnaire after the Summit period ended.
Results: Enhanced surveillance detected seven notable events associated with the 19 target diseases. None of these spread nor affected the G20 Summit. A total 66 people from 35 of 39 organizations responded to the questionnaire. Findings showed rapid information sharing occurred through the Analysis Center and feedback reports were considered useful.
Conclusion: Enhanced surveillance and feedback reports facilitated information sharing on infectious diseases across Osaka municipalities during the G20 Summit. This approach can be useful for similar events in the future but should be adapted to the context and needs of the event and stakeholders.
