|Contexte||Official surveillance system relies on official laws. The Lebanese Law related to communicable diseases issued on the 31st December 1957 requests from physicians and healthcare facilities to report to the MOPH selected communicable diseases.
On the other hand, the MOPH issues continuously decisions, circulars, and memos that specifies technical aspects of the national surveillance system (case definitions, forms…).
|Objectives||- Measure disease burden and describe the characteristics. This includes: a) Measure incidence, prevalence, and mortality rates; b) Describe event/disease by time, place and person; c) Monitor trends; d) Identify high risk populations or areas; e) Identify risk factors; f) Evaluate specific diseases control programs.
- Detect alerts and outbreaks. The detection of an outbreak gives an opportunity to investigate, find etiologies and implement corrective measures, thus aiming to reduce cases and prevent later outbreaks. Early warning and response system refers to the outbreak detection at early stages; when timely corrective measures can prevent additional new cases and stop the natural evolution of the outbreak.
