简要总结
This study aims to investigate the epidemiology of SARS-CoV-2 infection among: i) HCW who triage patients with suspected SARS-CoV-2 infection and provide care to COVID-19 patients; and ii) laboratory personnel who test clinical samples for SARS-CoV-2 infection. After the second wave of the pandemic enrolment will be widen to any person working at the study hospitals.

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 do sero-epidemiology assessment.(2022)
- To analyse immune responses to SARS-CoV-2 infection.(2022)
- To investigate the possibility of viral re-infection in this population during the study period.(2022)
- 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)
