This issue of the ECDC Communicable Disease Threats Report (CDTR) covers the period 7-13 January 2024 and includes updates on SARS-CoV-2, measles, diphtheria, Middle East respiratory syndrome coronavirus (MERS-CoV) and poliomyelitis.
This report contains genetic and antigenic characterization data generated at the Worldwide Influenza Centre for viruses with collection dates after 31 January 2023 until 31 August 2023.
Several viral and bacterial respiratory pathogens are expected to continue co-circulating at variable levels during the coming months, and contribute to increased morbidity and mortality during this period. This is typical of every winter season.
This report provides updated baseline data for monitoring future changes in the distribution of autochthonous Crimean-Congo haemorrhagic fever and its associated vectors for Europe and its neighbouring areas.
Varicella is caused by the varicella-zoster virus (VZV), which also causes shingles (herpes zoster). The virus typically affects children aged 2‒8 years.
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.
Poliovirus is highly contagious and infected individuals shed virus in the faeces and from oral secretions, thus the mode of transmission is person-to-person, both via the faecal-oral and the oral-oral routes.
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.
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.
