Why is Population Coverage Important in Epidemiology?

In epidemiology, population coverage is vital for several reasons:

Disease Control: Adequate coverage can lead to herd immunity, reducing the spread of infectious diseases.
Resource Allocation: Understanding coverage helps in the effective allocation of resources to areas with lower coverage levels.
Program Evaluation: It serves as a metric for evaluating the success or failure of health interventions.
Health Equity: Identifying gaps in coverage can highlight disparities in health access and outcomes, guiding efforts to address these inequities.
