European Immunization Week (EIW) is marked across Europe every year in the final week of April. It aims to raise awareness of the importance of immunisation for the general health and well-being of the European and wider population.
In connection with the European Immunization Week, ECDC releases data indicating an increase in cases of vaccine-preventable diseases such as measles and pertussis, after decreased levels during the COVID-19 pandemic.
Every month ECDC provides detailed epidemiological overview of the worldwide transmission of dengue in its weekly threat report (Communicable Diseases Threat Report).
Campylobacteriosis and salmonellosis were the most frequently reported zoonotic diseases in humans in the EU in 2022. For West Nile virus, an increase of the number of infections was observed.
Since January 2022, and as of 11 August 2023, 281 confirmed diphtheria cases, as per the EU case definition (2022: 224 cases, 2023: 57 cases), and four deaths were reported in the EU/EEA.
The mosquito species Aedes albopictus, a known vector of chikungunya and dengue viruses, is establishing itself further northwards and westwards in Europe, according to the latest data.
Between 2018 and 2020, nearly 20 000 surgical site infections (SSIs) were reported from a total of over 1.2 million surgical procedures in 13 EU/EEA countries participating in ECDC-coordinated SSI surveillance. Over 2 500 hospitals are part of this surveillance network.
As of 26 September 2022, 92 cases of diphtheria among migrants, including a fatal one, have been reported this year by seven European countries – Austria, Germany, United Kingdom, Norway, Belgium, France and Switzerland.
The number of reported human cases of illness caused by Campylobacter and Salmonella bacteria across Europe appears to have stabilised over the past five years, according to the latest report on zoonotic diseases by EFSA and ECDC.
