Conditions

Covid19, SARS-CoV-2 Infection

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.

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

MeasureTime frameDescription
Hand hygiene practices1 yearThe 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

MeasureTime frameDescription
Acceptability of hand hygiene technology1 yearStudy 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 seroconversion1 yearNumber 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
