• [Pre-print, not peer reviewed] Analysis of epidemic characteristics during and after lockdowns from Rhode Island, Massachusetts, and Pennsylvania – states that successfully reopened in May 2020 without subsequent summer waves – showed changes in age-dependent mixing patterns. Using several daily data streams and mobility data, population-average mixing rates dropped by >50% during lockdown. However, elderly individuals were less able to reduce contacts during lockdown than younger individuals, which potentially led to concentrated outbreaks among elderly congregate settings.
