Topic:

  • Based on a modeling study based on Ontario, Canada, enacting lockdown policies at the county level would cause significantly fewer person-days of closure compared to enacting them at the province level, even under the same trigger threshold for cases and in a scenario with high intercounty travel. The authors conclude that these findings suggest local strategies may be better suited for handling the tail-end of the pandemic.
