Epidemiological update: Measles - monitoring European outbreaks, 23 March 2017

Epidemiological update

​From September 2016 to 17 March 2017, Romania has reported 3 799 cases. In 2016, a number of EU/EEA countries reported measles outbreaks and an increase in the number of cases continues to be observed in 2017. Previous and ongoing measles outbreaks in other EU countries have been epidemiologically linked to the current outbreak in Romania. However, additional knowledge on genotypic characterisation of the virus is needed to allow further insight into the epidemiological investigations.

​A measles outbreak in Romania has been ongoing since February 2016 and cases continue to be reported despite ongoing response measures that have been implemented at national level through reinforced vaccination activities.

From September 2016 to 17 March 2017, Romania has reported 3 799 cases. In 2016, a number of EU/EEA countries reported measles outbreaks and an increase in the number of cases continues to be observed in 2017. Previous and ongoing measles outbreaks in other EU countries have been epidemiologically linked to the current outbreak in Romania. However, additional knowledge on genotypic characterisation of the virus is needed to allow further insight into the epidemiological investigations.

ECDC Assessment

The progress towards elimination of measles in the European Region of WHO is assessed by The European Regional Verification Commission for Measles and Rubella Elimination (RVC). Member States of the WHO European Region are making steady progresstowards the elimination of measles. At the fifth meeting of the RVC for Measles and Rubella in October 2016, of 53 countries in the WHO European Region, 24 (15 of which are in EU/EEA) were declared to have reached the elimination goal for measles, andan additional 13 countries (nine in EU/EEA) were concluded to have interrupted endemic transmission for less than 36 months, meaning they are on their way to achieving the elimination goal. However, six EU/EEA countries were judged to still haveendemic transmission of measles: Belgium, France, Germany, Italy, Poland, Romania.
