Epidemiological update: Measles - monitoring European outbreaks as of 09 Jun 2017

___

​Romania is experiencing a large outbreak of measles since February 2016. Cases continue to be reported despite ongoing response measures that have been implemented at national level through reinforced vaccination activities. Between 1 January 2016 and 6 June 2017, Romania has reported 6 619 measles cases, including 29 deaths.

In 2016, several additional EU/EEA countries reported measles outbreaks, and an increase in the number of cases continues to be observed in 2017.

Some previous and ongoing measles outbreaks in other EU/EEA countries have been epidemiologically linked to the current outbreak in Romania.

ECDC assessment

  • Measles outbreaks continue to occur in EU/EEA countries.
  • There is a risk of spread and sustained transmission in areas with susceptible populations.
  • The national vaccination coverage remains less than 95% for the second dose of MMR in the majority of EU/EEA countries.
  • The progress towards elimination of measles in the WHO European Region is assessed by the European Regional Verification Commission for Measles and Rubella Elimination (RVC).
  • Member States of the WHO European Region are making steady progress towards 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 the EU/EEA) were declared to have reached the elimination goal for measles, and 13 countries (nine in the EU/EEA) were concluded to have interrupted endemic transmission for between 12 and 36 months, meaning they are on their way to achieving the elimination goal.
  • However, six EU/EEA countries were judged to still have endemic transmission: Belgium, France, Germany, Italy, Poland and Romania.
  • More information on strain sequences would allow further insight into the epidemiological investigation.
  • All EU/EEA countries report measles cases on a monthly basis to ECDC and these data are published every month.
  • Since 10 March 2017, ECDC has been reporting on measles outbreaks in Europe on a weekly basis through epidemic intelligence activities.


Actions

  • ECDC published a rapid risk assessment on 6 March.
  • ECDC monitors measles transmission and outbreaks in the EU/EEA on weekly basis through enhanced surveillance and epidemic intelligence activities.
