The EUVAC-NET survey: national measles surveillance systems in the EU, Switzerland, Norway, and Iceland.

The EUVAC-NET network undertook a questionnaire study on measles surveillance systems in EU member countries, Switzerland, Norway and Iceland. All questionnaires were completed. Surveillance systems for measles are implemented in 16 of the 18 countries. Most countries have some case based data and in all countries the shift is towards case based surveillance for measles, though there are differences between countries concerning case definitions and classifications. A two-dose MMR vaccination schedule is implemented in all the EUVAC-NET countries but methods used for estimation of vaccination coverage are diverse.
