This issue of the ECDC Communicable Disease Threats Report (CDTR) covers the period 12 - 18 November 2023 and includes updates on SARS-CoV-2 variant classification, West Nile virus, multistate outbreak of salmonella, and an overview of respiratory virus epidemiology in the EU/EEA.
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).
From 1 January–24 October 2023, 335 laboratory-confirmed Salmonella Enteritidis ST11 cases belonging to three distinct microbiological clusters have been reported in 14 EU/EEA countries, the United Kingdom and the United States, affecting all age groups.
Prevalence data from sources such as population surveys can be a useful complement to case based surveillance data for hepatitis B. 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 B.
Since August 2022, cases of Salmonella Senftenberg have been identified in 13 countries worldwide. Case interviews suggest cherry-like tomatoes as a possible vehicle of infection.
