French: taux de létalité

Portuguese: rácio de casos fatais

Czech: smrtnost (letalita)

What is its purpose?

The indicator assesses the number of people who died of a disease divided by the number of people who have the disease. It is useful for determining the severity of the disease outbreaks.

How to Collect and Analyse the Required Data

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.

Disaggregate by

Disaggregate the data by gender and age groups.

Important Comments
