This scientific report provides an overview of highly pathogenic avian influenza (HPAI) virus detections in poultry, captive birds, wild birds, and mammals that occurred in and outside Europe between 2 September and 1 December 2023, as well as human cases due to avian influenza viruses up until 1 December 2023.
In 2022, the first and second most reported zoonoses in humans were campylobacteriosis and salmonellosis, respectively. The number of cases of campylobacteriosis and salmonellosis remained stable in comparison with 2021.
Campylobacteriosis and salmonellosis were the most frequently reported zoonotic diseases in humans in the EU in 2022. For West Nile virus, an increase of the number of infections was observed.
This issue of the ECDC Communicable Disease Threats Report (CDTR) covers the period 26 November - 2 December 2023 and includes updates on human infection with influenza A(H1N2)v, influenza A(H5N1), an overview of respiratory virus epidemiology in the EU/EEA, respiratory infections due to Mycoplasma pneumoniae in the EU/EEA, HIV/AIDS surveillance 2023 (2022 data), West Nile virus, SARS-CoV-2 variant classification, and poliomyelitis.
This Reporting Protocol describes data collection for influenza, COVID-19, and other respiratory viruses (such as RSV or new viruses of public health concern) in the EU/EEA and wider WHO European Region. Data collection is integrated for most datasets in line with the operational considerations for respiratory virus surveillance in Europe.
This issue of the ECDC Communicable Disease Threats Report (CDTR) covers the period 19 - 25 November 2023 and includes updates on updates SARS-CoV-2 variant classifications, the increase of pediatric respiratory infections in China, Avian influenza in fur farms, West Nile virus, cholera, and an overview of respiratory virus epidemiology.
Genetic and antigenic characterization data generated at the Worldwide Influenza Centre for viruses with collection dates after 31 January 2023 until 31 August 2023 informed the WHO influenza vaccine composition meeting (VCM) in September 2023 when recommendations were made for the southern hemisphere (SH) 2024 influenza season.
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.
The Global Influenza Surveillance and Response System (GISRS), led by WHO, is used for the international virological and epidemiological surveillance of human influenza.
