The document discusses Colorado's response to reducing the R0 value of COVID-19 through social distancing measures. It provides estimates that Colorado's initial R0 was between 3-4, meaning one infected person would spread it to 3-4 others. Various social distancing measures are outlined, from March 13th school closures to a March 26th statewide stay-at-home order, with models projecting their impact on lowering the effective R0 and reducing ICU bed demand and death estimates. Success is defined as not overwhelming hospital systems and allowing the quickest return to normalcy while planning for surge capacity and PPE.
