In 2023, significant increases in the number of measles cases and outbreaks were observed globally, including in 40 of the 53 countries of the European region, and in at least ten EU/EEA countries. Measles cases are expected to continue increasing in the EU/EEA in the coming months due to sub-optimal vaccination coverage for measles containing vaccines (MCV) in a number of EU/EEA countries, the high probability of importation from areas experiencing high circulation and the fact that the coming months represent the seasonal peak of the virus.
