Current mortality rates are around 3-4%. A mortality rate of 1% already assumes a large number of unreported cases. I saw estimates of 0.7% but they seem wildly optimistic in how many people having reported.
1% only assumes 66-75% unreported cases. With estimates of asymptomatic/low-severity infections above 80%, the ratio of infections that never get reported as cases is likely to be higher than that.
