TRACE: Contact tracing: Implementation in line with citizens' preferences for willingness to participate

Source and contact investigation (BCO), carried out by GGDs, is one of the pillars of infectious disease control. But direct evidence on the outcomes of BCO is limited. In addition, BCO is laborious, time-sensitive and dependent on the context and the willingness of citizens to participate. Objective Researchers use data from the GGDs to study the timeliness, reporting of contacts, and the personnel costs of BCO. They do this for notifiable infectious diseases, including Mpox, Shigellosis and Tuberculosis, and socio-demographic factors that can influence this. In addition, they conduct a discrete choice experiment to investigate the willingness and preferences for participation in BCO of Dutch citizens. Expected results Based on the findings, the researchers provide advice for GGDs and guidelines for the use of BCO in different situations. Insights into the willingness and preferences of citizens are also important to make the BCO better suited to their needs and thus possibly increase participation in BCO.
