This paper describes outbreak trends observed school from December 2021 when many public health measures place. School data five jurisdictions included, representing 76% total population. Epidemiological curves generated, cases' age distribution over time examined descriptive statistics on size calculated. most primary schools (42%).

Abstract Setting Early in the COVID-19 pandemic, Public Health Agency of Canada (PHAC) and provincial/territorial (P/T) public health identified need for a coordinated response to complex multijurisdictional outbreaks. The first large industrial worksite outbreak highlighted risk transmission within these congregate work settings, broader community(ies), develop setting-specific frameworks. Intervention PHAC assembled team provide national support outbreaks May 2020. Outbreak Response Unit (ORU) worked with P/T partners guiding principles investigation processes, guidance documents, tools (e.g., minimum data elements questionnaires). Outcomes ORU, partners, onsite safety staff leveraged guidelines, process documents (including elements), enhanced case questionnaires respond multiple investigations worksites. Clear roles/responsibilities along standardized data, allowed more efficient earlier implementation mitigation measures. Implications Multijurisdictional importance collaboration industry onsite. assembly was important facilitate information sharing technical support. Lessons learned recommendations on preparation, detection, management, communication are included enhance framework applicable future emerging or re-emerging pathogens epidemic and/or pandemic potential.
