Incidence is best defined as a measure of new cases of a disease that occur within a specific time frame. It focuses on the rate at which new cases are identified in a population, providing insight into the risk of contracting the disease during that period. This definition is crucial for public health officials and researchers because it helps track disease outbreaks, assess the effectiveness of preventive measures, and allocate resources for health interventions.

Understanding incidence is essential for grasping how diseases spread and evolve over time. By measuring new cases rather than all existing ones, public health efforts can be directed towards prevention and early intervention strategies that can effectively reduce the spread of a disease in the community.
