Canadian COVID-19 Antibody and Health Survey, Cycle 1

The Canadian COVID-19 Antibody and Health Survey will collect information in two parts. The first part is an electronic questionnaire about general health and exposure to COVID-19. The second part is an at-home finger-prick blood test, which is sent to a lab to determine the presence of COVID-19 antibodies. <p>The data will be used to: <ul> <li>estimate how many Canadians test positive for antibodies even if they have never had symptoms of COVID-19</li> <li>better understand the social distancing behaviours of Canadians and their general health during the pandemic.</li> </ul> </p> <p>This important information will help evaluate the extent of the health status associated with the COVID-19 pandemic such as the prevalence of infection even for people who have never had symptoms, among a representative sample of Canadians. Through the integration with health and social administrative data, the survey will also provide a platform to explore emerging public health issues, including the impact of COVID-19 on health and social well-being. It also aims to shed light on immune responses to SARS-CoV-2 in a diversity of communities, age brackets, populations, and occupational groups across the nation.</p>

加拿大新冠抗体与健康调查（Canadian COVID-19 Antibody and Health Survey）将分两部分开展信息采集工作。第一部分为涵盖一般健康状况与新冠病毒暴露风险的电子问卷；第二部分为居家指尖采血检测，采集的样本将被送至实验室以检测新冠病毒抗体的存在情况。<p>该数据将用于：<ul><li>估算即便从未出现新冠症状的加拿大人中，抗体检测呈阳性的人群比例；</li><li>更深入地了解加拿大人在疫情期间的社交距离行为与整体健康状况。</li></ul></p><p>此项关键信息将助力评估新冠疫情关联健康状态的覆盖范围，例如在具有全国代表性的加拿大人样本中，即便从未出现症状者的感染流行率。通过与健康及社会行政数据的整合，本调查还将搭建可用于探索新发公共卫生问题的研究平台，其中包括新冠疫情对健康与社会福祉的影响。此外，本调查旨在阐明加拿大境内不同社区、年龄组别、人口群体及职业群体针对严重急性呼吸综合征冠状病毒2型（SARS-CoV-2）的免疫应答情况。</p>
