Strengthening surveillance systems by vigorous case investigation, including laboratory confirmation, is one of these key strategies. In line with the elimination goal, Surveillance guidelines for measles, rubella and congenital rubella syndrome in the WHO European Region are intended to provide technical advice on the design and implementation of surveillance programmes. The purpose of disease surveillance is to provide information for public health action, i.e. to guide the planning, implementation and evaluation of public health interventions and systems. It is important that disease surveillance is considered within the overall information needs of an immunization programme, and that it supports effective programme management.
