Retrospective surveillance and enhanced case-finding of congenital rubella syndrome cases

The generic protocol presented in this document was developed for ECDC by fellows of the EPIET programme to provide EU/EEA Member States with an adaptable tool to estimate the incidence of congenital rubella syndrome (CRS) cases in their countries. This study protocol describes a process that any EU/EEA country can use to retrospectively identify probable CRS cases in infants in the three years preceding the study’s implementation and to evaluate the completeness of their current CRS surveillance system.
