European monthly measles monitoring (EMMO) - Issue 11

Surveillance report
Publication series: Bi-annual measles and rubella monitoring report

ECDC monitors measles transmission in the EU and EEA/EFTA countries and produces monthly epidemiological updates. The European Monthly Measles Monitoring (EMMO) report has two sections. The surveillance section reports officially validated national figures on measles reported by countries to The European Surveillance System (TESSy). The Epidemic Intelligence section reports information from multiple sources including national websites, the Early Warning and Response System (EWRS), TESSy, validated media reports, and personal communication from national authorities. The period covered in the Epidemic Intelligence section will differ between countries, and the number of cases reported should be treated as preliminary data.
