The objective of this project was to explore the main challenges in the analysis of contact tracing data and to identify areas of improvement that could improve the use of contact tracing data for surveillance and public health management, as well as to facilitate the sharing of information and experience between European countries. Member States of the Union/European Economic Area (EU/EEA). The specific objectives were to:

  • Perform an analysis of contact tracing data in three countries (Italy, Ireland and Spain) and describe the methods used to analyze this data, the main challenges that arose during this analysis and how these challenges were overcome.
  • Assess the feasibility of using a list of contact tracing indicators for countries to report from their contact tracing systems.

Accordingly, suggested best practices, together with a set of essential variables and a set of suggested variables for calculating contact tracing indicators, are offered. These indicators are useful for understanding transmission dynamics within the population, understanding locations or settings of high transmission, and measuring the impact of mitigation measures.
