Table 1.
The adjusted association between county-level objective social distancing scores and COVID-19 incidence and mortality in the US
| COVID-19 | Adjusted IRR (95% CI) per 1-unit increase in objective social distancing scorea | p-value |
|---|---|---|
| Incidence | 0.71 (0.57–0.87) | < 0.001 |
| Mortality | 0.65 (0.55–0.76) | < 0.001 |

A total of 3,054 counties were included in the analysis. Counties in which social distancing data were unavailable (n=192) were excluded. Social distancing data from February 24, 2020 (earliest available for all counties) and COVID-19 incidence and mortality from April 29, 2020 (when the first stay-at-home guidance was lifted) were used in modeling. All models are adjusted for county-level Hispanic ethnicity, non-white race, percent aged 50 years and older, percent males, median household income, population density, and obesity prevalence, and state-level cumulative COVID-19 testing rate
