NCT04387890

Brief Summary

The investigators will follow a single prospective cohort of 50 Health Care Workers in the Hospital Italiano de Buenos Aires (Argentina) from May 15th to August 31st 2020 using antibody testing for SARS-CoV-2 IgM and IgG at baseline and every 2 weeks in order to assess the incidence of COVID-19, the prevalence of anti-SARS-CoV-2 antibodies (IgM and IgG) and incidence of reinfection or reactivations of previous COVID-19 using viral gene sequencing in this cohort.

Outcome Measures

Primary Outcomes (3)

  • Prevalence of anti SARS-CoV-2 antibodies (IgM and IgG) in health personnel

    Patients that has a positive result for IgM or IgG at baseline first test

    Baseline at study inclussion

  • COVID-19 incidence through serology-based screening and/or compatible symptoms in health personnel previously known to be unexposed to the virus

    Patients that has a positive result for IgM or IgG or PCR during follow up

    During 3 months follow up

  • Incidence of reactivation/reinfection for COVID-19 in health personnel with a positive serology for SARS-CoV-2

    Patients with confirmed previous SARS Cov 2 antibodies that reactivate symptomons or new increase in antibodies title during follow up

    During 3 months follow up

Study Arms (1)

Serologic Screening

Participants will be screened for IgM and IgG SARS-CoV-2 antibodies at baseline and every 2 weeks. Participants showing symptoms compatible with COVID-19 will undergo nasopharyngeal swab for PCR testing for diagnosis. Participants recovered from COVID-19 will have to have 2 negative and consecutive nasopharyngeal swab PCR tests in order to return to work.

Diagnostic Test: Serologic SARS-CoV-2 screening

Interventions

Quantitative Indirect Chemiluminescence Immunoassay (CLIA) to access SARS-CoV-2 specific IgM and IgG serum antibody level every 2 weeks during follow up

Serologic Screening
