Surveillance systems provide data that can identify unusual patterns or clusters of diseases. This information can trigger further investigation and confirm an outbreak or emerging health threat. Early detection through surveillance involves several key steps:
1. Data Collection: Continuous and systematic collection of health-related data. 2. Data Analysis: Regular analysis to identify trends, patterns, and anomalies. 3. Interpretation: Interpreting the data to understand the public health implications. 4. Dissemination: Sharing the information with relevant stakeholders, including public health authorities, healthcare providers, and the general public.
