  • The overall infection fatality ratio (IFR) for the state of Indiana, excluding institutionalized persons and children under 12 years of age, was 0.3%. Stratifying the IFR across demographic groups resulted in an IFR of 0.01% among those <40 years of age, 1.7% among those ≥60 years of age, 0.2 among white patients, and 0.6% among non-white patients. The investigators used a statewide non-random sample to obtain 187,802 cumulative infections.
