Disease Prevention: Facilitates the development of strategies to prevent the spread of infectious diseases. 3. Health Equity: Aims to reduce health disparities by ensuring all population groups have access to necessary services. 4. Emergency Preparedness: Enhances the ability to respond to public health emergencies and outbreaks.
