结局指标
主要结局
To determine the prevalence of symptomatic and asymptomatic SARS-CoV-2 infections among HCW.
时间窗: 2020
To determine the prevalence of symptomatic and asymptomatic PCR-confirmed SARS-CoV-2 infections among HCW using a systematic sampling strategy, coupled with investigation when clinically indicated.
次要结局

- To establish if common cold coronaviruses (CCCV) immunity confers protection against SARS-CoV-2 infection or disease severity(2022)
- To evaluate COVID-19 vaccine effectiveness (VE) amongst HCWs, against any PCR-confirmed SARS-CoV-2 infection.(2022)
- To measure humoral and cell mediated immune responses to COVID-19 vaccines stratified by previous SARS-CoV-2 infection.(2022)
