Tóm tắt

 Non-pharmaceutical interventions (NPIs) remain the only widely available tool for controlling the ongoing SARS-CoV-2 pandemic. We estimated weekly values of the effective basic reproductive number (R<

 ) using a mechanistic metapopulation model and associated these with county-level characteristics and NPIs in the United States (US). Interventions that included school and leisure activities closure and nursing home visiting bans were all associated with a median R<

  below 1 when combined with either stay at home orders (median R<

  0.97, 95% confidence interval (CI) 0.58?1.39) or face masks (median R<

 eff<
 /sub>
  0.97, 95% CI 0.58?1.39). While direct causal effects of interventions remain unclear, our results suggest that relaxation of some NPIs will need to be counterbalanced by continuation and/or implementation of others.
