UNASSIGNED: Using influenza surveillance indicators within Canada\'s FluWatch program from seasons 2014-2015 to 2018-2019, national PISA thresholds were developed and assessed against seasonal data for seasons 2019-2020 to June of 2022-2023.
UNASSIGNED: Canada developed thresholds for each required indicator (transmissibility, seriousness of disease and impact) for multiple WHO-recommended parameters. The thresholds were assessed against four seasons, and it was determined that there was a good agreement between the PISA assessments and the characterization of the season by FluWatch epidemiologists.
UNASSIGNED: With confidence in the validity of the PISA thresholds, the FluWatch program will begin to share PISA assessments weekly through the FluWatch report in the 2023-2024 seasons to help characterize influenza activity in Canada and inform responses to the seasonal influenza epidemic.
使用2014-2015年至2018-2019年加拿大FluWatch计划中的流感监测指标,根据2019-2020年至2022-2023年6月的季节性数据制定并评估了国家PISA阈值。
■加拿大为每个所需指标制定了阈值(可传输性,疾病的严重性和影响)对于世卫组织推荐的多个参数。阈值是根据四个季节进行评估的,并确定PISA评估与FluWatch流行病学家对季节的表征之间有很好的一致性。
■对PISA阈值的有效性充满信心,FluWatch计划将开始每周通过FluWatch报告分享2023-2024年季节的PISA评估,以帮助描述加拿大的流感活动,并为季节性流感流行提供应对措施。
