摘要

背景:68例实验室确诊的2019冠状病毒病(COVID-19)病例(阿尔伯塔省12例,萨斯喀彻温省56例)与2020年6月1日至4日在阿尔伯塔省一家医院举行的聚会,以及2020年6月9日至11日在萨斯喀彻温省北部第一民族社区举行的守灵/葬礼有关。目的全面描述疫情的流行病学和传播链,为在守丧/葬礼上多次引入COVID-19的假设提供依据。方法由AB和SK当地公共卫生部门进行病例调查和接触者追踪,加拿大公共卫生机构进行病例集中分析。绘制了流行病曲线和可传播期甘特图,以支持或反驳在守丧/葬礼上是否多次引入COVID-19。结果发病日期为2020年5月31日至7月1日。年龄从2岁到80岁(中位年龄=43岁)。5例住院治疗;没有人员死亡。现有病例暴露信息支持了在守丧/葬礼上多次引入COVID-19的假设。AB和SK的公共卫生当局于2020年7月20日宣布疫情结束;根据最后一个原发病例发病后的两个潜伏期(即28天)。结论在多辖区暴发期间,数据共享、卫生当局之间的协调和集中分析对于了解导致暴发的事件和围绕传播链的可能假设至关重要。

Multijurisdictional outbreak of COVID-19 associated with a wake/funeral event in a northern Saskatchewan First Nations community.
Background Sixty-eight laboratory-confirmed cases of the coronavirus disease 2019 (COVID-19) (12 in Alberta [AB], 56 in Saskatchewan [SK]) were linked to a gathering at a hospital in Alberta on June 1-4, 2020, and a wake/funeral in a First Nations community in northern Saskatchewan on June 9-11, 2020. Objective The objectives were to provide a comprehensive description of the epidemiology of the outbreak and describe the chains of transmission to inform the hypothesis that there were multiple introductions of COVID-19 at the wake/funeral. Methods Case investigation and contact tracing was conducted by local public health in AB and SK. The Public Health Agency of Canada conducted a centralized case analysis. An epidemic curve and a Gantt chart for period of communicability were created to support or refute whether there had been multiple introductions of COVID-19 at the wake/funeral. Results Illness onset dates ranged from May 31 to July 1, 2020. Ages ranged from 2 to 80 years (median age=43 years). Five cases were hospitalized; there were no deaths. The available case exposure information supports the hypothesis that there had been multiple introductions of COVID-19 at the wake/funeral. Public health authorities in AB and SK declared the outbreak over on July 20, 2020; based on two incubation periods (i.e. 28 days) following the illness onset of the last primary case. Conclusion During multijurisdictional outbreaks, data sharing, coordination across health authorities and centralized analysis is essential to understanding the events that lead to the outbreak and possible hypotheses around chains of transmission.
