The proposed project will implement and evaluate a brief Community Health Worker (CHW) intervention through the Albany Area Primary Health Care, a rural Federally Qualified Health Center (FQHC). The primary goal of this study is to maximize effective outreach, education, and communication through CHWs in order to facilitate improved COVID-19 vaccine confidence and uptake in underserved and vulnerable communities. CHWs will be deployed to the homes of adults with increased risk of morbidity and mortality (i.e., African Americans or Latinos with uncontrolled diabetes or prediabetes, age <50 years, and non-COVID-19 vaccinated) in order to educate them about diabetes, COVID-19 and related vaccines. Health assessments, including blood glucose measurement, will be conducted on the indexed patient and offered to all other adult family members in the household (i.e., "bubble"). Adults with Type 2 diabetes likely live in households with other adults who have or are at increased risk for diabetes (i.e., prediabetes and obesity).1 It is expected that they will also share similar COVID-19 exposure risk. The specific aims are to: 1) Evaluate a community-driven education program to increase and enhance COVID-19 vaccine confidence and uptake in individuals with uncontrolled diabetes and their families (i.e., their "bubble") and 2) Evaluate a community-driven education program to improve diabetes self-management behaviors and related outcomes (e.g., blood glucose) in individuals with uncontrolled diabetes in rural, Southwest Georgia.

COVID-19 can trigger a dysregulated immune response, and previous studies have shown that immune modulation can improve outcomes in hospitalized patients. This trial is designed to determine whether intensification of immune modulation early in the course of the disease (while patients are on low flow oxygen) with abatacept (active arm) combined with standard of care (SOC) improves recovery as compared with placebo + SOC (placebo arm). For both groups, intensification of immunomodulation will be provided as part of SOC in case of signs of disease progression (patient requires high flow nasal oxygen (HFNO) or more support) and/or if the patient has rapidly increasing oxygen requirement.

Given the likelihood of COVID-19 remaining an endemic disease among high-risk populations, establishing effective mitigation interventions will be critical to stemming community transmission. Criminal justice-involved individuals are extremely important to reducing community-based SARS-CoV-2 transmission due to their increased risk of contracting SARS-CoV-2 while incarcerated and their likelihood of living in congregate settings after incarceration. The investigators will evaluate an onsite Point-of-Care SARS-CoV-2 testing and education strategy in a corrections-focused community-based organization and its impact on improving testing uptake, mitigation behaviors(e.g. mask wearing, hand hygiene, social distancing, vaccine uptake when available), and cost-effectiveness.
