ECDC initiated a survey of EU/EEA countries to evaluate preparedness planning and risk mitigation initiatives implemented at the country level for people exposed to highly pathogenic avian influenza virus A(H5N1).
The aim of this survey was to review the expertise, capabilities and capacities for detection and characterisation of avian and other zoonotic influenza viruses in national influenza reference laboratories in the European Union/European Economic Area (EU/EEA), in members of the European Reference Laboratories for influenza (ERLINet), and in EU Enlargement policy countries.
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.
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.
Since June 2017, a cross-border outbreak of Salmonella Virchow ST16 has been ongoing in five EU/EEA countries, the UK, and the US. A total of 210 cases have been reported. No deaths have been reported. A majority of cases have been linked to local restaurants serving kebab meat.
An increased reporting of shigellosis cases, mainly caused by Shigella sonnei, among travellers returning from Cabo Verde has been ongoing in the European Union/European Economic Area (EU/EEA), the United Kingdom (UK), and the United States (US) since September 2022.

In recent weeks, respiratory syncytial virus (RSV) circulation in the EU/EEA has intensified, with increasing transmission rates in all population groups and an earlier-than-usual start of the season. Several EU/EEA countries are experiencing high RSV circulation and the number of severe acute respiratory infections (SARI) due to RSV is increasing. At this time of the year RSV infections are not unusual, however this year there is more RSV activity and it began earlier than in pre-COVID-19 seasons.
