About this study

Official title: Cohort Study of SARS-CoV-2 Incidence, Transmission, and Disease Severity in Healthcare Workers

Our long-term goal is to protect the health care workforce (HCW) caring for SARS-CoV-2-infected patients, their families, communities, and the general population. Our specific objective is to rapidly establish a prospective cohort to characterize the factors related to viral transmission and disease severity in a large healthcare system. We addressed this hypothesis by recruiting and longitudinally following 546 HCW and a comparison group of 283 non-HCW within a large academic health system, Rutgers Biomedical and Health Sciences (RBHS). By intensively following participants over a several year period (2020-2024) and collecting serial biospecimens (nasopharyngeal/throat swabs, blood, and saliva) and questionnaire data at multiple time points, we will uniquely characterize SARS-CoV-2 transmission and risk factors for COVID-19 among HCW and our larger academic community.

Read the detailed description

This prospective longitudinal cohort study is comprised of: (1) 546 HCW from two RBHS hospitals: Robert Wood Johnson University Hospital (RWJUH) in New Brunswick and University Hospital (UH) in Newark ; (both hospital presidents have approved the study) (2) 283 NHCW from Rutgers faculty, staff, and hospital employees without patient contact. At baseline, investigators will obtain nasopharyngeal or throat swabs, saliva, and blood (for detecting SARS-CoV-2 positivity and immunity, respectively) and collect questionnaire data on sociodemographic factors, lifestyle, and medical history. In the first phase of the study, nasopharyngeal/throat swabs, saliva, and blood collection were collected every two weeks for two months, after which monthly samples were collected for four additional months (9 visits total, including baseline). Weekly questionnaire data and daily temperature data was collected from each participant for the first two months of the study. Investigators will calculate and compare incidence rates and risk factors of SARS-CoV-2 positivity and COVID-19 in healthcare workers and non-healthcare workers and assess symptoms and severity of disease. Through additional funding, we will continue to administer follow-up questionnaires and collect additional specimens (primarily for serology) through 2024.

Our specific aims are:

  1. To assess the baseline prevalence of SARS-CoV-2 and COVID-19 in the study population.
  2. To characterize the natural history of SARS-CoV-2 infection in a diverse US workforce, including the incidence of asymptomatic infections and critical illness.
  3. To determine the incidence of SARS-CoV-2 and COVID-19 in healthcare workers compared with non-healthcare workers.
  4. To identify the risk factors for acquiring SARS-CoV-2 and developing COVID-19.
  5. To determine the duration and extent of SARS-CoV-2 shedding.
  6. To determine immune responses to SARS-CoV-2 infection and or vaccinations.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 15 May 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Prevalence (time frame: up to 24 weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04336215, which also lists 15 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 May 2026.
