Social determinants of health (SDOH) linked to COVID-19 case growth in Tennessee dynamically shift in importance over time. SDOH include social, physical and environmental factors that impact community health such as age, race, gender, access to transportation, access to primary care and community vaccination rates. Twelve of these SDOH features demonstrated the highest feature importance across all predictive models during the study period. Size and color are used to emphasize SDOH feature importance at each time point. large, red (
) bubbles connote the top ranked SDOH feature while small dark blue (
) bubbles signify least importance of a given feature at each time point. Black bubbles (
) represent the least important feature at each time point compared with the other top ranked SDOH data elements.
