Sero-prevalence of Coronavirus Disease 2019 (COVID-19) in Healthcare Workers

March 7, 2021 updated by: Egyptian Center for Research and Regenerative Medicine
The medical and paramedical staff of the front-line services are potentially exposed to SARS-CoV-2. Therefore, despite the application of standard protective measures, it is possible that a certain number of these personnel have already contracted SARS-CoV-2, including in its asymptomatic form. Serological testing in this context would be useful for deploying immune healthcare workers as to limit the risk of viral infection and transmission. Therefore, it is of utmost importance to prove that the serological response entails the production of neutralizing antibodies.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 60 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Probability Sample

Study Population

Age-stratified sample from general population with 3 subgroups:

  1. Healthcare workers (HCWs), comprising frontline doctors, nurses, health attendants, and receptionists.
  2. Healthy blood donors and healthy subjects in blood bank or laboratory (routine examinations as pre-employment, likely to be representative of the general population
  3. Convalescents

Description

Inclusion Criteria:

  • Not previously diagnosed with COVID-19 except for convalescents
  • Not currently symptomatic with fever or respiratory symptoms (cough, dyspnea)

Exclusion Criteria:

  • Patients with fever or respiratory symptoms (cough, dyspnea)
  • Refusal to give informed consent, or contraindication to venipuncture.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Healthcare workers (HCWs)
Biological: Specific anti-SARS-CoV-2 antibodies

A serum sample needs to be collected from each participant upon recruitment into the investigation All samples will be tested by the rapid test (Artron, Artron Laboratories, Burnaby, Canada), IgM / IgG which is an antibody capture Immunochromatografac assay for simultaneous detection of IgM and IgG in serum or plasma for COVID -19 in samples.

All samples will be tested for total Immunoglobulins and IgG in samples for COVID-19 virus by Ortho clinical diagnostics chemiluminescent technique (Ortho, Raritan, USA).

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
