Background:
Measles incidence in the 53 Member States of the World Health Organization (WHO) European Region has fallen dramatically in recent decades. The European Regional Verification Commission for Measles and Rubella Elimination (RVC) verified that 43 member states had interrupted endemic measles transmission for ≥12 months by the end of 2017. However, measles incidence in the region increased sharply in 2018 compared to 2017. The purpose of this article is to assess the current status of measles in the Region in relation to its elimination goal. It also discusses challenges and actions needed to reach this goal.
Methods:
Measles surveillance data presented for 2017 and 2018 (as of 1 February 2019) were submitted by all 53 member states. The measles elimination status of countries was obtained from the 2018 report of the seventh meeting of the RVC.
Results:
In 2017, 25,863 measles cases were reported in 44 countries of the WHO European Region. In 2018, 82,596 measles cases were reported in 47 countries. Most cases were reported by Ukraine (64%) and Serbia (6%). Age was known in 82,588 cases: 8% were <1 year old, 17% were 1-4 years old, 38% were 5-19 years old and 37% were ≥20 years old. Data on vaccination status were provided for 76% of the cases, of which 62% were unvaccinated. Seventy-two measles-related deaths were reported from 10 countries.
Conclusions:
For the elimination of measles in the European Region, a high population immunity rate and accurate epidemiological surveillance remain essential. Long-term political commitment by all Member States in these areas is crucial to attain the elimination goal.
Insights
Measles cases surged in Europe in 2018 after a decade of decline, with most cases in unvaccinated individuals. Achieving measles elimination requires high vaccination rates and robust surveillance across all WHO European Member States.
Area of Science:
- Public Health
- Epidemiology
- Infectious Disease Control
Background:
- Measles incidence significantly decreased in the WHO European Region over recent decades.
- By 2017, 43 member states had interrupted endemic measles transmission.
- However, a sharp increase in measles cases was observed in 2018.
Purpose of the Study:
- To assess the current status of measles in the WHO European Region concerning elimination goals.
- To identify challenges and necessary actions for achieving measles elimination.
Main Methods:
- Utilized measles surveillance data submitted by all 53 WHO European Member States for 2017 and 2018.
- Determined country-specific measles elimination status based on the 2018 European Regional Verification Commission for Measles and Rubella Elimination report.
Main Results:
- In 2017, 25,863 measles cases were reported across 44 countries; this rose to 82,596 cases in 47 countries in 2018.
- Ukraine and Serbia reported the highest number of cases. Of the vaccinated cases, 62% were unvaccinated.
- Seventy-two measles-related deaths were reported from 10 countries.
Conclusions:
- High population immunity and accurate epidemiological surveillance are critical for measles elimination in the European Region.
- Sustained political commitment from all Member States is essential to achieve the measles elimination goal.

Kinetics of Drug Elimination
Drug clearance depends on the rate of drug elimination and its plasma concentration. Another important parameter is the half-life of a drug, which is the time required for its concentration to decrease by half. In most cases, drug clearance follows first-order...
Enhanced Elimination of Poison
Antidotes serve a crucial role in counteracting the effects of poison by inhibiting enzymes responsible for producing harmful drug metabolites. In some cases, these toxic metabolites can be neutralized by endogenous cosubstrates, which are maintained at specific concentrations to prevent interaction with cellular macromolecules and subsequent cell death.
