Clinical Trial Summary

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.

Outcome

Type Measure Description Time frame Safety issue
Primary To determine the prevalence of symptomatic and asymptomatic SARS-CoV-2 infections among HCW. 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. 2020
Secondary To define the duration of viral "shedding". To define the duration of "shedding" (using molecular based PCR methods) of SARS-CoV-2 in HCW who are identified to be infected with the virus. 2020
Secondary To do sero-epidemiology assessment. To undertake serial sero-epidemiology studies on prevalence of SARS-CoV-2 antibodies among HCW. 2022
Secondary To analyse immune responses to SARS-CoV-2 infection. To analyse immune responses (humoral and cell mediated) to SARS-CoV-2 infection. 2022
Secondary To investigate the possibility of viral re-infection in this population during the study period. To investigate the possibility of viral re-infection during the different pandemic waves in this population during the study period. 2022
Secondary To establish if common cold coronaviruses (CCCV) immunity confers protection against SARS-CoV-2 infection or disease severity To establish if common cold coronaviruses (CCCV) immunity confers protection against SARS-CoV-2 infection or disease severity by measuring antibodies to CCCV. 2022
Secondary To evaluate COVID-19 vaccine effectiveness (VE) amongst HCWs, against any PCR-confirmed SARS-CoV-2 infection. To evaluate COVID-19 vaccine effectiveness (VE) amongst HCWs, against any PCR-confirmed SARS-CoV-2 infection. 2022
Secondary To measure humoral and cell mediated immune responses to COVID-19 vaccines stratified by previous SARS-CoV-2 infection. To measure humoral and cell mediated immune responses to COVID-19 vaccines stratified by previous SARS-CoV-2 infection. 2022
