Health planning faces several challenges including: - Data Limitations: Incomplete or inaccurate data can hinder the identification of health priorities and the evaluation of interventions. - Resource Constraints: Limited financial and human resources can restrict the scope and scale of health interventions. - Political and Societal Factors: Political will, public opinion, and societal norms can influence the implementation of health plans. - Emerging Health Threats: New and re-emerging diseases, such as pandemics, pose significant challenges to health planning and require adaptive and responsive strategies.
