[Pre-print, not peer-reviewed] A pandemic influenza model with COVID-19 parameters applied to a nursing home setting showed that the attack rate was more sensitive to identification and isolation of asymptomatic cases than implementation of non-pharmaceutical interventions (NPIs). Varying NPI levels from baseline to rigorous measures had no significant effect on attack rate in a scenario without isolation of asymptomatic cases, whereas NPI scenarios showed large reductions in attack rate  when used in conjunction with 90% isolation (up to 43% reduction). Hospitalizations, ICU admissions, and mortality rate were all reduced as the attack rate fell.
