Measles Wipes Out 72 European Kids in 2018, WHO Says

Measles, a childhood infection caused by a virus killed 72 children and adults in Europe last year, the World Health Organisation (WHO) has said.

According to monthly country reports for January to December 2018 (received as of 01 February 2019), 82 596 people in 47 of 53 countries contracted measles. In countries reporting hospitalisation data, nearly 2/3 (61%) of measles cases were hospitalised.

The total number of people infected with the virus in 2018 was the highest this decade, three times the total reported in 2017 and 15 times the record low number of people affected in 2016

More children in the WHO European Region are being vaccinated against measles than ever before; but progress has been uneven between and within countries, leaving increasing clusters of susceptible individuals unprotected, and resulting in a record number of people affected by the virus in 2018.

 In light of measles data for the year 2018 released on Thursday, WHO urges European countries to target their interventions to those places and groups where immunization gaps persist.

The surge in measles cases in 2018 followed a year in which the European Region achieved its highest ever estimated coverage for the second dose of measles vaccination (90% in 2017).

More children in the region received the full two-dose series on time, according to their countries’ immunisation schedules, in 2017 than in any year since WHO started collecting data on the second dose in 2000. Coverage with the first dose of the vaccine also increased slightly to 95%, the highest level since 2013. However, progress in the region, based on achievements at the national level, can mask gaps at subnational levels, which are often not recognized until outbreaks occur.

“The picture for 2018 makes it clear that the current pace of progress in raising immunization rates will be insufficient to stop measles circulation. While data indicate exceptionally high immunization coverage at regional level, they also reflect a record number affected and killed by the disease. This means that gaps at local level still offer an open door to the virus,” says Dr Zsuzsanna Jakab. “We cannot achieve healthier populations globally, as promised in WHO’s vision for the coming five years, if we do not work locally. We must do more and do it better to protect each and every person from diseases that can be easily avoided.”

While immunisation coverage has improved overall in the Region, many people remain susceptible.

• Estimated coverage with the second dose of measles vaccine was below the 95% threshold to prevent circulation (that is, to achieve “herd immunity”) in 34 countries of the Region in 2017.
• Subnational coverage rates point to disparities even within countries.
• Suboptimal coverage for either dose sets the stage for transmission in the future.

The European Vaccine Action Plan 2015–2020 (EVAP) lays out a strategy endorsed by all 53 Member States to eliminate both measles and rubella. Most importantly, at least 95% of every population needs to be immune, through two doses of vaccination or prior exposure to the virus, to ensure community protection for everyone – including babies too young to be vaccinated and others who cannot be immunised due to existing diseases and medical conditions.

“In adopting EVAP, all countries in the European Region agreed that elimination of measles and rubella is possible, and is also a cost-effective way to protect people of all ages from avoidable suffering and death,” says Dr Nedret Emiroglu, Director of the Division of Health Emergencies and Communicable Diseases, WHO Regional Office for Europe.

Forty-three European countries interrupted transmission of endemic measles for at least 12 months as of the end of 2017. Some of them also managed to limit the spread of the virus following importation to very few cases in 2017 and 2018, showing that elimination of the disease is well within reach for the whole region. “Progress in achieving high national coverage is commendable. However, it cannot make us blind to the people and places that are still being missed. It is here that we must now concentrate increased efforts. We should never become complacent about our successes but continue to strive to reach the final mile. Together we can make this happen,” concludes Dr Emiroglu.

Many factors contribute to suboptimal immunization coverage and the spread of measles. To prevent outbreaks and eliminate measles, countries need to sustain high national and subnational immunization coverage with two doses of measles-containing vaccine, as well as identify and address all pockets of under-immunisation among their populations.

The Regional Office continues to work with countries in the Region to enhance their immunization and disease surveillance systems. This includes building capacities and providing guidance to:

• ensure that all population groups have equitable access to vaccination services and that these are convenient;
• identify who has been missed in the past and reach them with the vaccines they need;
• ensure that health workers are vaccinated to prevent transmission in health facilities, and that they have sufficient technical knowledge about vaccines and the immune system to feel confident in recommending vaccination to their patients;
• strengthen trust in vaccines and health authorities;
• secure access to a timely and affordable supply of vaccines;
• improve outbreak detection and response;
• listen and respond to people’s concerns, and respond to any health event that could be potentially related to vaccine safety.

Most of the countries struggling with suboptimal immunisation coverage against measles in the region are middle-income countries. The Regional Office is working with these countries to implement a coordinated strategy to address targeted programme areas.
