A, Daily positivity rates of SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) as points and 7-day moving averages (number positive/number tested over the plotted date and preceding 6 days) as solid lines by race/ethnicity. Statistically significant differences (P < .001) in daily positivity rates were evaluated across groups with 1-way analysis of variance (ANOVA). Multiple post hoc pairwise comparisons (Tukey test) of each group (black, white, other) to the Latino reference group also demonstrated significant differences (P < .001 for each pairwise comparison). B-E, Testing volume stratified by SARS-CoV-2 test result and grouped by race/ethnicity. This included an omnibus ANOVA comparison with significance (P < .05) resulting in correction for multiple pairwise comparisons using the Latino group as reference.
