To assess geographic disparities in COVID-19 transmission, hospitalizations, and deaths by evaluating spatial clustering and demographic risk factors across communities.
Geocoded and analyzed 221,843 COVID-19 cases across census tracts in Orange County, California, between March 2020 and February 2021.
Employed generalized additive models within a Poisson framework, smoothing over census tract centroids and conducting 1,000 location permutations to test spatial randomness and temporal variation across pandemic surges.
Significant spatial clustering of cases, hospitalizations, and deaths was identified in northern Orange County across multiple pandemic surges.
Adjusted spatial models demonstrated significant associations between COVID-19 risk and percent minority population (aRR: 1.06, 95% CI: 1.06 to 1.07), average household size (aRR: 1.06, 95% CI: 1.05 to 1.07), and percent service industry employment (aRR: 1.05, 95% CI: 1.04 to 1.06).
