In Japan, respiratory syncytial virus (RSV) infection generally has occurred during autumn and winter. However, a possible change in the seasonal trend of RSV infection has been observed recently. The current study was conducted to determine whether the epidemic season of RSV infection in Japan has indeed changed significantly. We used expectation-based Poisson scan statistics to detect periods with high weekly reported RSV cases (epidemic cluster), and the epidemic clusters were detected between September and December in the 2012-2016 seasons while those were detected between July and October in the 2017-2019 seasons. Non-linear and linear ordinary least squares regression models were built to evaluate whether there is a difference in year trend in the epidemic seasonality, and the epidemic season was shifted to earlier in the year in 2017-2019 compared to that in 2012-2016. Although the reason for the shift is unclear, this information may help in clinical practice and public health.

Introduction: The discussions in this theme provided an opportunity to address the unique hazards facing the Pacific Rim., Methods: Details of the methods used are provided in the preceding paper. The chairs moderated all presentations and produced a summary that was presented to an assembly of all of the delegates. Since the findings from the Theme 3 and Theme 7 groups were similar, the chairs of both groups presided over one workshop that resulted in the generation of a set of action plans that then were reported to the collective group of all delegates., Results: The main points developed during the presentations and discussion included: (1) communication, (2) coordination, (3) advance planning and risk assessment, and (4) resources and knowledge., Discussion: Action plans were summarized in the following ideas: (1) plan disaster responses including the different types, identification of hazards, focusing training based on experiences, and provision of public education; (2) improve coordination and control; (3) maintain communications, assuming infrastructure breakdown; (4) maximize mitigation through standardized evaluations, the creation of a legal framework, and recognition of advocacy and public participation; and (5) provide resources and knowledge through access to existing therapies, the media, and increasing and decentralizing hospital inventories., Conclusions: The problems in the Asia-Pacific rim are little different from those encountered elsewhere in the world. They should be addressed in common with the rest of the world.
