What is the number of new cases of a disease in a population over a specific period of time compared with the healthy population?

The number of new cases of a disease in a population over a specific period of time is referred to as the incidence rate. It measures the frequency of new infections or occurrences of the disease within a defined population and time frame. This rate is often expressed as the number of new cases per a specific number of individuals (e.g., per 1,000 or 100,000 people) to provide context against the healthy population. This helps in understanding the impact of the disease on public health and in resource allocation for prevention and treatment.
