Covid19, SARS-CoV-2 Infection
Conditions
Brief summary
This project will build on an existing CDC funded cooperative agreement in the Dominican Republic with the Brigham and Women's Hospital (2018-2023) that includes (i) prospective COVID-19 and AFI surveillance at two health facilities and (ii) a nationally representative cross-sectional community-based serological survey of approximately 7,000 healthy adults and children targeting SARS-CoV-2 and other AFI pathogens to be conducted between April and June 2021. This linked study will establish a nested cohort of 2,000 participants enrolled in the national serological survey and prospectively monitor them for COVID-19 symptoms, conduct serial serological testing, implement molecular surveillance for SARS-CoV-2 and sequencing for variants of concern, implement and evaluate WASH mitigation measures, and monitor uptake and perceptions of COVID-19 vaccines.

Study design
Intervention model description
This is a prospective cohort study that aims to prospectively monitor 2,000 community-based study participants with serial serological screening for SARS-CoV-2 and enhanced molecular surveillance for active infection. Nested within this cohort is a randomized trial that will allocate study participants into two arms: thoe that receive versus do not receive alcohol-based hand sanitizer (ABHS) through the course of the study.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Hand hygiene practices | 1 year | The average daily frequency of study participant hand hygiene events over the previous seven days will be assessed using standardized survey questionnaires at 0-, 3-, 6-, 9-, and 12-months. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Acceptability of hand hygiene technology | 1 year | Study participants preference for different hand hygiene technology (e.g. soap and water, ABHR) as measured using a five-point Likert Scale at 0-, 3-, 6-, 9-, and 12-months. |
| SARS-Cov-2 seroconversion | 1 year | Number of study participants that seroconvert from SARS-CoV-2 seronegative to seropositive at time points 0-, 6-, and 12-months as assessed by presence of anti-nucleocapsid immunoglobulin |
