The chart shows the probability of dying if infected, sometimes called the IFR or Infection Fatality Rate by Age. Notice from the chart that those younger than 50 are virtually immune from dying. They may get infected and sick but the chances they die if infected, the IFR, are close to zero. Those over age 50, if infected, face a non-zero and, in the case of the elderly, a significant risk of dying if infected.
