Among countries and US states implementing stay-at-home mandates between April and May 2020, a longer period of time between the first reported case and implementation of mandates was associated with a longer time to reach peak daily case and death counts. For US states, each additional day between first case and mandate implementation predicted an extra 1.1 days and 1.0 days to reach peak cases and deaths, respectively. However, among states in the latest 10% to implement mandates, this effect predicted an extra 35.3 days and 38.3 days to reach peak cases and deaths, respectively.
