1. Identification of Public Health Issues: Recognizing and prioritizing health problems that need intervention. 2. Evidence Gathering: Collecting data through epidemiological studies to understand the problem and identify potential solutions. 3. Policy Formulation: Developing policies based on scientific evidence, feasibility, and potential impact. 4. Stakeholder Engagement: Involving various stakeholders, including the public, policymakers, and healthcare providers, to gather input and ensure support. 5. Implementation: Putting the policy into action through appropriate channels. 6. Evaluation: Assessing the effectiveness of the policy in achieving its objectives and making necessary adjustments.
