Detailed explanation-1: -Incidence refers to the occurrence of new cases of disease or injury in a population over a specified period of time. Although some epidemiologists use incidence to mean the number of new cases in a community, others use incidence to mean the number of new cases per unit of population.

Detailed explanation-2: -Incidence versus prevalence Incidence contrasts with prevalence, which includes both new and existing cases. For example, a person who is newly diagnosed with diabetes is an incident case, whereas a person who has had diabetes for 10 years is a prevalent case.

Detailed explanation-3: -Prevalence and incidence data are two of the most important tools used by epidemiologists to track the spread of disease. We know that prevalence is a measure of how many people are currently infected with a disease, while incidence is a measure of how many new cases of disease there are in a population over time.
