Dataset: Elisa cohort study on SARS-CoV-2 transmission

The Elisa study is a population-based cohort study in Lübeck and the surrounding area (northern Germany) with the aim to determine the prevalence and influencing factors of infections with the Sars-CoV2 over a one-year period. The study collected data from April 2020 to February 2021. A cohort of 3000 randomly selected individuals were screened by swab (PCR) for active corona infection and blood draws were performed to determine antibodies at seven time points. In addition, continuous app-based questionnaires were administered to study participants regarding symptoms, behavior, and social factors.
The data set consists of a file with baseline variables and examination results for the 3000 participants and another file with the continuous survey data (90,000 interviews).

埃莉萨研究（Elisa study）是一项在德国北部吕贝克市及其周边地区开展的基于人群的队列研究，旨在明确为期一年周期内严重急性呼吸综合征冠状病毒2（SARS-CoV-2）感染的流行率及其影响因素。该研究的数据采集时段为2020年4月至2021年2月。研究团队对随机遴选的3000名个体组成的队列，通过拭子采样（聚合酶链式反应，PCR）筛查活动性新冠病毒感染，并在7个时间点采集血液样本以检测抗体水平。此外，研究人员向所有参与者发放了基于应用程序的持续性问卷调查，内容涵盖症状表现、个人行为与社会相关因素。
本数据集包含两类文件：其一为3000名参与者的基线变量与检测结果文件，其二为包含9万次访谈记录的持续性调查数据文件。
