Contact tracing is a key intervention in infectious disease control, but it can be challenging to implement successfully for diseases like COVID-19, where infections spread quickly and often without symptoms. Apps such as the CoronaMelder in the Netherlands were introduced with the promise of fast and comprehensive contact identification but were hampered by insufficient uptake by the population.  

Within its research line on innovative infectious disease control, the PDPC is working on preparing the contact tracing approach for the next pandemic. By investigating the process and impact of contact tracing, we aim to design innovations that can optimize contact tracing, both for minimizing disease spread and keeping track of transmission networks.
