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.
In 2022, 1 149 confirmed cases of invasive meningococcal disease (IMD), including 110 deaths, were reported in 30 European Union/European Economic Area Member States.
Meningococcal disease is caused by Neisseria meningitidis, a bacterium with human carriers as the only reservoir. It is carried in the nose, where it can remain for long periods without producing symptoms.
Mumps is a viral infection first described by Hippocrates that in its classical form causes acute parotitis and, less frequently, orchitis, meningitis and pneumonia.
In 2021, 1 567 cases of mumps were reported to ECDC by 27 European Union/European Economic Area(EU/EEA) Member States, with an overall notification rate of 0.4 cases per 100 000 population. This wassignificantly lower than the notification rates reported during the previous four years (range 1.7-4.2).
This issue of the ECDC Communicable Disease Threats Report (CDTR) covers the period 6 - 12 August 2023 and includes updates on measles, COVID-19, swine flu, mpox, diphtheria, West Nile virus, avian influenza, dengue, Crimean-Congo haemorrhagic fever, and invasive meningococcal disease.
