This document is an update of the joint guidance that was published in 2011 by the European Centre for Disease Prevention and Control (ECDC) and the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA).
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 8-14 October 2023 and includes updates on hepatitis A, influenza A(H5N1), COVID-19, the Rugby World Cup 2023, West Nile virus, measles and diphtheria.
Prevalence data from sources such as population surveys can be a useful complement to case based surveillance data for hepatitis C. Case-based surveillance has limitations as most diagnosed cases are chronic in nature and detection of cases depends largely on testing practices. Prevalence data can therefore contribute towards a fuller understanding of the epidemiology of hepatitis C.
