Following several years of steady progress toward elimination of measles in the WHO European Region, the number of countries having achieved or sustained elimination of the disease has declined, This was the conclusion of the European Regional Verification Commission for Measles and Rubella Elimination (RVC) based on an assessment of annual status updates for 2018 submitted by the 53 Member States of the Region.

The RVC determined that for the first time since the verification process began in the Region in 2012, four countries like Albania, Czechia, Greece and the United Kingdom lost their measles elimination status.

“Re-establishment of measles transmission is concerning. If high immunization coverage is not achieved and sustained in every community, both children and adults will suffer unnecessarily and some will tragically die,” says Dr Günter Pfaff, Chair of the RVC.

The RVC was, on the other hand, pleased to conclude that Austria and Switzerland attained elimination status, having demonstrated the interruption of endemic transmission for at least 36 months.

For the Region as a whole, as of the end of 2018, 35 countries are considered to have achieved or sustained measles elimination (compared to 37 for 2017), 2 have interrupted the endemic transmission of measles (for 12–35 months), 12 remain endemic for measles and 4 that had previously eliminated the disease have re-established measles transmission.

The surge in cases that began in 2018 has continued into 2019, with approximately 90 000 cases reported for the first half of the year. This is already more than that recorded for the whole of 2018 (84 462).

The ongoing circulation of measles in the Region continues to be internally classified within WHO as a Grade 2 emergency. This designation allows the Organization to mobilize the technical, financial and human resources needed to support the affected countries.

“Great efforts to control this highly contagious disease have brought us a long way towards regional elimination. However, ongoing measles outbreaks demonstrate that more is needed. Through activation of the emergency response, WHO has increased its focus on measles elimination and upgraded its action. This is the time and opportunity to address any underlying health system, social determinants and societal challenges that may have allowed this deadly virus to persist in this Region,” says Dr Zsuzsanna Jakab, WHO Regional Director for Europe.

The RVC is an independent panel of experts that meets annually to assess measles elimination status in the Region based on extensive annual reports submitted by each country. It met on 12–14 June 2019 in Warsaw, Poland to evaluate reports for 2018 and based its conclusion on several factors including measles surveillance data, routine immunization coverage, outbreak response, and the reach of supplemental immunization campaigns and other activities.

The RVC also concluded that the situation for rubella has improved 39 countries achieved or sustained elimination status, three interrupted endemic transmission and 11 countries continue to be considered endemic for rubella.
