Study Details

Study Description

Brief Summary

The overall goal of this study is to understand the immune response (IgG) to SARS-CoV-2 to fill critical knowledge gaps in the natural history of this virus and to inform the development of future infection mitigation efforts. The study team aims to assess the prevalence of circulating IgG antibodies to SARS-CoV-2 and the factors associated with sero-prevalence. These data will be used to estimate the total population that has been exposed to the virus (asymptomatic and symptomatic), the proportion of the population that may be protected by natural immunity, and the proportion that is susceptible. Data obtained from this research will be shared with the Florida Department of Health.

Arms and Interventions

Arm Intervention/Treatment
Participants age 18-34

Up to 300 participants age 18-34 who received an invitation by mail and are free of fever at time of interview.

Diagnostic Test: SARS-CoV-2 Antibody Analysis
10 ml of blood will be drawn for antibody analysis. Participants who test SARCS-CoV-2 positive will be invited to participate in follow-up antibody testing at 4 weeks and at 3 months.

Diagnostic Test: Weck-cel Swab Collection
A Weck-cel swab will be used to collect secretions from the mucosal epithelium

Behavioral: Web Based Questionnaire
A brief web enabled questionnaire will be administered to collect information related to demographics, SARS-CoV-2 exposure history, past symptoms, comorbidities associates with increased infection and disease risk, as well as immunosuppression status and use to immunosuppressive medications.

Participants age 35-54

Up to 300 Participants age 35-54 who received an invitation by mail and are free of fever at time of interview.

Outcome Measures

Primary Outcome Measures

  1. Percentage of Participants who test positive for SARS-CoV-2 antibodies at first visit [At study start]

    All participants who respond to study invitation letter will be tested for SARS-CoV-2 antibodies after completing a web-based questionnaire.

  2. Percentage of Participants who test positive for SARS-CoV-2 antibodies at second visit [At 4 weeks]

    Participants who tested positive for SARS-CoV-2 antibodies at first study visit will be tested for antibodies to SARS-CoV-2 again at 4 weeks.

  3. Percentage of Participants who test positive for SARS-CoV-2 antibodies at third visit [At 3 months]

    Participants who tested positive for SARS-CoV-2 antibodies at second study visit will be tested for antibodies to SARS-CoV-2 again at 3 months.
