Racial, Ethnic, and Geographic Disparities in Novel Coronavirus (SARS-CoV-2) Test Positivity in North Carolina

Emerging evidence suggests that Black and Hispanic communities in the United States are disproportionately affected by coronavirus disease 2019 (COVID-19). A complex interplay of socioeconomic and healthcare disparities likely contribute to disproportionate COVID-19 risk. 

Led by DICON physician Dr. Nick Turner, a team from Duke University School of Medicine, Global Health Institute, and Nicholas School of the Environment and UNC Gillings School of Global Public Health conducted a geospatial analysis to determine whether individual and neighborhood level attributes predict local odds of testing positive for SARS-CoV-2. The team analyzed 29,138 SARS-CoV-2 tests within the 6 -county catchment area for Duke University Health System from March to June 2020. They used generalized additive models to analyze the spatial distribution of SARS-CoV-2 positivity. Adjusted models included individual-level age, gender, and race, as well as neighborhood level ADI, population density, demographic composition, and household size.
