Main developments

    • The ECDC measles and rubella monitoring report is published twice a year.
    • The January issue reports on the previous calendar year, while the July issue focuses on the most recent measles and rubella season and presents the data collected over the past 12 months.
    • Visualised measles and rubella data are available online through the measles [1] and rubella [2] pages of the ECDC Surveillance Atlas of Infectious Diseases, updated monthly.
    • In addition, ECDC produces monthly highresolution measles maps [3].
  • Measles
    • Between 1 January and 31 December 2016, 3 767 cases of measles were reported by 30 EU/EEA countries.
    • Twenty-eight countries reported consistently throughout this 12-month period. 
    • Romania accounted for 42% of all cases reported during this period.
    • Measles is targeted for elimination in Europe.
    • The measles notification rate was below the elimination target (one case per million population) in 18 of the 30 reporting countries.
    • Eight of these 18 countries reported zero cases.
    • Twelve reporting countries had a notification rate above this indicator, with Romania reporting the highest rate (79.3 cases per million population).
    • The diagnosis of measles was confirmed by positive laboratory results (serology, virus detection or isolation) in 69% of all cases.
    • The highest age-specific notification rate was observed in infants under one year of age (76.1 cases per million population), followed by children aged 1–4 years (55.3 cases per million population).
    • These were the age groups most affected in Romania.
    • Twenty-eight percent of the cases were ≥20 years old. 
    • Of all cases with known age, 94% had a known vaccination status and of these, 87% were reported as unvaccinated.
    • In the target group for the first dose of routine childhood MMR (measles-mumps-rubella) vaccination (children 1–4-years), 84% of all cases were unvaccinated. Some countries also administer the second dose in this age group. 
    • During the period 1 January to 31 December 2016, nine measles-related deaths were reported, eight in Romania and one in the United Kingdom.
    • Four of these deaths were in unvaccinated infants <1 year of age.
    • No cases were complicated by acute measles encephalitis.
  • Rubella
    • Twenty-eight EU/EEA countries reported 1 307 rubella cases during the period 1 January to 31 December 2016.
    • Twenty-five countries reported consistently for the 12-month period.
    • Rubella is targeted for elimination in Europe.
    • The rubella notification rate was lower than the elimination target (one case per million population) in 26 of the 28 countries.
    • Seventeen of these 26 countries reported zero cases.
    • Of the two countries with a notification rate above this indicator, the highest rate was reported by Poland (30.1 cases per million population).
    • Poland reported 1 144 rubella cases, 88% of all reported cases in the 12-month period.
    • This figure should be interpreted with caution because only 19 cases were confirmed by laboratory testing.
    • Data were reported in an aggregated format.
    • The highest number of cases was observed in 1–4-year-olds and 5–9year-olds.
  • Progress towards WHO elimination goals
    • In 2015, the vaccination coverage rate for the first dose of measles-containing vaccines was at least 95% in 17 EU/EEA countries, and for the first dose of rubella-containing vaccines at least 95% in 15 EU/EEA countries.
    • In eight countries, the vaccination coverage rate for the second dose of measles-containing vaccine was at least 95%.
    • Five countries did not submit data concerning the second dose for 2014 or 2015. 
    • At the fifth meeting of the Regional Verification Commission for Measles and Rubella on 24—26 October 2016 [4], of 53 countries in the WHO European Region, 24 (15 EU/EEA) were declared to have achieved the elimination goal for measles and 24 (16 EU/EEA) for rubella (based on 2015 data).
    • In addition, 13 countries (nine EU/EEA) were deemed to have interrupted endemic transmission for less than 36 months for measles and 11 for rubella (six EU/EEA), meaning that they are on their way to achieving the elimination goal.
    • If the elimination goal is to be achieved, high-quality surveillance is essential, while the vaccination coverage rates in young children targeted by routine vaccination programmes will have to be increased for both measles and rubella, and immunisation gaps closed in adolescents and adults who have missed opportunities for vaccination in the past.
