COVID-19 |
Design:
Cross-sectional surveys of (1) adults residing in senior living facilities and attending outpatient healthcare facilities, and (2) the general population in each selected research site community.
Population:
- Adults residing in senior living facilities (nursing homes, assisted or independent living facilities) and attending outpatient healthcare facilities in neighborhoods of selected research sites
- Adults and children (> 2 months of age) in neighborhoods of selected research sites
Study Size:
For each research site, up to 3,920 individuals will be enrolled from one, two, or all three of the following populations (must include at least community venues):
- senior living facilities (nursing homes, assisted or independent living facilities; n = 500)
- outpatient healthcare facilities (n = 500)
- community venues distributed across four age categories (0-17, 18-39, 40-59, 60+ years) (n = 730 per stratum or 2920)
Total sample size = 3,920 x up to 20 clinical research sites
Study Duration:
Approximately sixteen (16) months for overall project. Two (2) months for protocol development and institutional review board (IRB) approval, followed by:
- Facility-based surveys: 12 months (3 months for site preparation and initiation, 3 months for enrollment/sample collection, 4 months for shipping and laboratory testing*, 2 months for close-out), concurrent with
-
Time-location sampling (TLS) surveys: 14 months (3 months for site preparation and initiation, 6 months for enrollment/sample collection, 6 months for shipping and laboratory testing*, 2 months for close-out)
- Some activities will be concurrent with enrollment
Study Location:
Catchment areas surrounding US-based Clinical Research Sites (CRSs) of the: HIV Prevention Trials Network (HPTN), HIV Vaccine Trials Network (HVTN), Infectious Diseases Clinical Research Consortium (IDCRC), International Maternal Pediatric Adolescent AIDS Clinical Trials Group (IMPAACT), and the AIDS Clinical Trials Group (ACTG); to be specified in the Site Announcement Memo
Study Methods:
Blood collection for SARS-CoV-2 antibody testing and characterization of the serologic response to SARS-CoV-2 infection; nasal mid-turbinate swab collection for SARS-CoV-2 RNA testing; collection of saliva in a subset of participants to evaluate the performance of diagnostic SARS-CoV-2 assays using these matrices; administration of tablet-based survey. Medical records abstraction for senior living facility participants who are unable to respond to the study survey.

Group/Cohort |
---|
Senior Living Facilities
Adults residing in senior living facilities (nursing homes, assisted or independent living facilities)
|
Outpatient Healthcare Facilities
Adults attending outpatient healthcare in neighborhoods of selected research sites
|
General Communities
Adults and children (>2 months of age) in neighborhoods of selected research sites
|
- To estimate the prevalence of SARS-CoV-2 IgG seropositivity among individuals in communities surrounding selected NIAID clinical research sites [ Time Frame: Baseline ]
- To estimate prevalence of SARS-CoV-2 infection based on results of SARS-CoV-2 RNA testing [ Time Frame: Baseline ]
- To estimate prevalence of SARS-CoV-2 infection by presence versus absence of symptoms consistent with COVID-19 [ Time Frame: Baseline ]
- To estimate seroprevalence of SARS-CoV-2 [ Time Frame: Baseline ]
Among:
- Those without past or current symptoms consistent with COVID-19
- Those with no prior positive SARS-CoV-2 testing, but who report close contact with confirmed or presumed cases
- Those with history of co-morbid medical conditions
- To assess association between demographic, clinical and social factors with SARS-CoV-2 infection and seroprevalence, with particular interest in racial and ethnic health disparities. [ Time Frame: Baseline ]Logistic regression using survey weights will be used to infer associations between the hypothesized socioeconomic, demographic and clinical predictors of SARS-CoV-2 infection and seroprevalence.
- To estimate potential size of populations for referral to COVID-19 prevention and treatment studies [ Time Frame: Baseline ]
- To assess knowledge, attitudes, and behavior about SARS-CoV-2 and COVID-19 through a study questionnaire [ Time Frame: Baseline ]
- To assess performance characteristics of PCR-based and serologic SARS-CoV-2 tests using saliva samples [ Time Frame: Baseline ]
Biospecimen Retention: Samples Without DNA
