Incidence and Prevalence: Examples Incidence/Incidence Rates Incidence Rates: Example Consider Chicken Pox, where the cumulative incidence rate is 20 percent per year, and 100 individuals are followed up. On average, after 6 months, 10 individuals will catch the disease. In diseases that happen only once (as with Chicken Pox), the 10 The rate ratio tells you how more (or less) common a particular event happened in an exposed group. For example, a ratio of 5 means that the event occurred at 5 times the rate in the exposed group than in the non-exposed group. Example 1: A study is undertaken to find out whether depression risks are higher The rate ratio tells you how more (or less) common a particular event happened in an exposed group. For example, a ratio of 5 means that the event occurred at 5 times the rate in the exposed group than in the non-exposed group. Example 1: A study is undertaken to find out whether depression risks are higher Understanding the Basics of Incidence When talking about online sample, incidence (or incident rate) is always part of the discussion. This article provides an overview of incidence and the terms targetable and Net Incidence. Example: Cumulative Incidence and Rate The mortality rate in the U.S. population in 2001 was 855 per 100,000 person-years (or 0.855 per 100 person-years) If everyone alive at the beginning of the year were followed for 5 years, The cumulative incidence of death (if the rate held constant) would be 4.2% at 5 years; The cumulative incidence of death (if the rate held constant) would be 8.2% at 10 years. The incidence rate and incidence proportion are two different views of the frequency with which events (e.g., cases) occur. Incidence involves (1) events, (2) a source population at risk of the event, and (3) the passage of time during which events occur. Incidence, in statistics, is the rate of occurrence of something or the number of times it occurs within a population at a particular time or time period. The rate of incidence is usually expressed as a fraction, for example, 48 cases of measles out of a population of 750 schoolchildren over the course of a winter.

Incidence is the rate at which a disease or event occurs or develops within a given population in a defined time period. It does not address specific causation or predict the course of a disease
