Epidemic surveillance implies continuous systematic collection, analysis and interpretation of health data, bearing in mind their temporal representation and spatial distribution. The data collected are essential for the planning, implementation and evaluation of public health practices. The final link in the surveillance chain is the application of this data in order to prevent and control the disease. The monitoring system implies the existence of functional capacities for data collection, analysis and submission to public health programs.

Implementation epidemic measures is currently the responsibility of state, entity, cantonal institutions, local communities and each individual. Competent institutions at various levels of government have issued a series of orders and recommendations related to measures of physical distance, hygiene, mass gatherings and the use of various public and private services. In order to more effectively monitor their activities and control the rapidly changing situation, it is necessary to further improve the system of epidemic surveillance.
