The probability of death due to the infection is calculated using Case Fatality Ratio (CFR). At the beginning of the outbreak the CFR was set to be around 4% in China, and 0.2% outside of China. However, as the pandemic progressed, we see the ratio has changed significantly and now is set to be 3.4%.
Calculating the CFR during the outbreak may prove quite difficult, and the rate which we see now will change again multiple times. Let’s try to understand this measure better.
