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.
The food-borne infections listeriosis and shigatoxigenic Escherichia coli are increasing in the EU/EEA and were in 2022 at levels higher than before the COVID-19 pandemic.
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.
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.
Since late February 2023 and up until 30 March 2023, 87 cases of botulism linked to intragastric injection of the botulinum neurotoxin (BoNT) have been reported.
Since late February 2023 and as of 10 March 2023, 67 cases of botulism linked to intragastric injection of the botulism neurotoxin (BoNT) have been reported in Germany (12), Austria (1), Switzerland (1) and Türkiye (53).
Hepatitis A cases in 2021 were at their lowest levels since EU-level hepatitis A surveillance began in 2007, while five other food and waterborne diseases are rising towards pre-pandemic levels. The information is revealed in the Annual Epidemiological Report 2021, of which six chapters are published today by ECDC.
