There is one clinical trial.
This is a prospective, epidemiological, cohort study to assess the feasibility of screening healthy asymptomatic workers for the presence of severe acute respiratory syndrome SARS-CoV-2 by pharyngeal swaps and serology at baseline, day 21 and day 40.
Description: Evaluation of immune responses to components of SARS-CoV-2 as well as evaluation of Swab for the presence of SARS-CoV-2 by PCR. Determination of the difference between the study groups in anti-SARS-CoV 2 seropositivity status. Analysis of trends in CD4/CD8 concentrations over time and correlation with immunoglobulin G (IgG) Levels and new assay evaluation.
Measure: Baseline (Visit 1) Time: BaselineDescription: Evaluation of Swab for the presence of SARS-CoV-2 by PCR and determination of the difference between the study groups in anti-SARS-CoV 2 seropositivity status.
Measure: Day 21 (Visit 2) Time: Day 21 (Visit 2)Description: Evaluation of immune responses to components of SARS-CoV-2 as well as evaluation of Swab for the presence of SARS-CoV-2 by PCR. Determination of the difference between the study groups in anti-SARS-CoV 2 seropositivity status and analysis of trends in CD4/CD8 concentrations over time and correlation with IgG Levels as well as new assay evaluation.
Measure: Day 40 (Visit 3) Time: Day 40 (Visit 3)
