Simulation study reveals that epidemic suppression is required to avoid healthcare collapse in the UK and US, indicating intense interventions must persist until vaccines arrive.

Key Points

To assess the potential effectiveness of non-pharmaceutical interventions in reducing transmission rates, peak healthcare demand, and mortality from COVID-19 in the UK and the US.
Applied an individual-based microsimulation epidemiological model calibrated to population demographics in Great Britain and the United States.
Evaluated two primary approaches: mitigation (slowing viral spread to protect vulnerable groups) and suppression (reversing epidemic growth to keep case counts low).
Modelled combinations of interventions including case isolation at home, household quarantine, population-wide social distancing, and educational institution closures.
Optimal mitigation policies (case isolation, household quarantine, and social distancing of high-risk populations) are projected to reduce peak healthcare demand by two-thirds and mortality by half.
Despite reductions, mitigation is projected to result in hundreds of thousands of deaths and overwhelm intensive care capacity many times over in both countries.
Effective suppression requires combining whole-population social distancing, home isolation, and household quarantine, which must be sustained or intermittently triggered until an effective vaccine is available to prevent epidemic rebound.
