Calculate the indicator's value by taking the following steps:
1) Assess the number of people who died from the disease during a pre-defined time period. If possible, collect and crosscheck the data from more sources, such as health centres, local authorities and burial societies.
2) Divide it by the total number of all people who had the disease during the same time period.
3) Multiply it by 100. The resulting percentage is the Case Fatality Rate.
