Introduction

Effective public health surveillance systems are critical for detecting, preventing, and controlling diseases and other health threats. These systems provide essential data for monitoring disease trends, identifying outbreaks, evaluating interventions, and informing public health policy. However, designing and implementing robust surveillance systems requires specialized knowledge and skills. This two-week training course addresses this need by providing participants with a comprehensive understanding of the principles, methods, and technologies used in public health surveillance. The course covers the entire surveillance cycle, from data collection and analysis to interpretation and dissemination. Participants will learn how to select appropriate data sources, design effective surveillance systems, ensure data quality, analyze surveillance data, and communicate findings to stakeholders. The course emphasizes practical application, using case studies and exercises to reinforce learning. By the end of the course, participants will be equipped with the knowledge and skills necessary to design, implement, and evaluate effective public health surveillance systems that contribute to improved public health outcomes.
