ARMOR Study: COVID-19 Seroprevalence Among Healthcare Workers

April 3, 2026 updated by: Columbia University

SARS-CoV-2 Seroprevalence Among Healthcare Workers: ARMOR Study Demonstration Project

The novel coronavirus (SARS-CoV-2) has spread all around the world and testing has posed a challenge globally. Health care providers are highly exposed and are an important group to test. On top of these concerns, health care workers are also stressed by the needs on responders in the COVID-19 crisis. The investigators will look at different ways to measure how common COVID-19 is among health care workers, how common is the presence of antibodies by serological tests (also known as serostatus). The investigators will describe health worker mental and emotional well-being and their coping strategies in their institutional settings. Lastly, the investigators will describe how knowing serostatus can affect individuals' mental and emotional well-being and how to cope in the midst of the COVID-19 response. This will help to how to better test and help healthcare workers in the COVID-19 pandemic and prepare for possible future outbreaks.

Study Overview

Status

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.

Detailed Description

The rapid spread of the novel coronavirus SARS-CoV-2 has resulted in pandemic levels and a global challenge in diagnosing infection. Diagnosing infection, defining recovery and immunity has been challenging. Health care providers in particular are very interested in knowing their status as they are highly exposed, and if infectious, can potentially transmit infection nosocomially (in the healthcare workplace setting) and to their household. In addition to understanding their exposure risk, infectious period, and immunity status, health care workers are reporting high levels of psychosocial distress including anxiety and burnout. The investigators aim to assess the baseline and cumulative seroprevalence of SARS-CoV-2 among health care workers using both quantitative and qualitative serological assays; describe psychosocial well-being and coping strategies among health workers in their institutional settings and describe how knowledge of one's serostatus affect psychosocial well-being, and coping strategies. Findings from this study will inform; 1) use of serological assays and testing algorithms, and 2) approaches to manage psychosocial stress for healthcare workers.

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
