COVID-19 Daily Average Incidence Rate

Measurement Period: Mar 3, 2023

This indicator shows the population-adjusted confirmed daily average new COVID-19 cases recorded in the preceding 7 days (for example, Jan 31 includes the average daily incidence rate between January 25 - January 31, 2020).

Numerator = daily average of confirmed new cases in preceding 7 days

Denominator = total population of the locale

Why is this important?

As a measure of incidence, incidence rate includes only new cases of disease in the numerator. The denominator is the number of persons in the population at the start of the observation period. In the outbreak setting, the term attack rate is often used as a synonym for risk. It is the risk of getting the disease during a specified period, such as the duration of an outbreak. By showing the daily average incidence rate per week, this approach helps prevent major events (such as a change in reporting methods) from skewing the data and better allows visualizations overtime.
