Planning interventions involves several steps: 1. Data Collection: Epidemiologists gather data on the incidence, prevalence, and distribution of diseases. 2. Risk Assessment: Identifying high-risk populations and factors contributing to disease spread. 3. Strategy Development: Formulating strategies based on data and risk assessment. 4. Implementation: Executing the intervention strategies. 5. Monitoring and Evaluation: Continuously assessing the effectiveness of interventions and making necessary adjustments.
