  • COVID-19 mitigation measures in Delaware, including stay-at-home orders, public mask mandates, and case investigations with contact tracing followed by isolation or quarantine, likely contributed to an observed 82% reduction in COVID-19 incidence, an 88% reduction in hospitalizations, and a 100% reduction in mortality in the state during late April–June. The authors note that barriers to case identification and contact tracing included that 83% of interviewed patients either refused to disclose contacts or could not recall them and cases were contacted a median of 8 days after receiving their test result.
