Estimation of Coronavirus Disease Case-Fatality Risk in Real Time.Emerg Infect Dis. 2020 08; 26(8):1922-1923.EI
We ran a simulation comparing 3 methods to calculate case-fatality risk for coronavirus disease using parameters described in previous studies. Case-fatality risk calculated from these methods all are biased at the early stage of the epidemic. When comparing real-time case-fatality risk, the current trajectory of the epidemic should be considered.
