In Europe, overall influenza activity continued to increase, with influenza positivity from sentinel sites remaining above the
epidemic threshold. Influenza A(H3N2) predominated among the subtyped influenza A viruses from sentinel sites, with some
detections of A(H1N1)pdm09 and B viruses. Nine countries reported widespread activity and/or at least medium intensity and 11
reported influenza positivity greater than 10% in primary care sentinel surveillance systems. In Eastern Europe, influenza
detections increased mostly due to A(H1N1pdm09) virus detections from non-sentinel sites in the Russian Federation but with
increased influenza detections reported also in other countries. Increased ILI activity was reported in some of these countries and
influenza-associated hospitalizations increased sharply in the Russian Federation. In Northern Europe, influenza detections were
predominantly influenza A followed by B viruses, with A(H3N2) predominant among the subtyped A viruses except detections in
non-sentinel surveillance from a few countries where A(H1N1)pdm09 predominated (Iceland, Ireland, Northern Ireland in the
United Kingdom of Great Britain and Northern Ireland (UK), and Norway). Influenza detections increased slightly in a few
countries (Ireland, Lithuania, Norway, Sweden and the UK). ILI increased to moderate levels in Denmark and slight increases
were reported in other countries, but ILI generally remained low. Influenza hospitalizations and admissions to intensive care unit
were at moderate levels in the UK. RSV activity (% positivity and number of notified hospitalizations for RSV) decreased but
remained elevated in Ireland and RSV- associated hospitalizations increased in the UK following trends of pre-COVID-19pandemic years. In Southwest Europe, influenza detections of predominantly A(H3N2) also continued to increase in some
countries, especially in France, Germany, Italy, Portugal and Switzerland while a decrease in detections was reported in Spain in
recent weeks. ILI also increased in some countries (Austria, France, Germany, Greece and Italy), especially in children and earlier
compared to previous seasons in some countries. ILI activity was reported as low in France and moderate in Italy. Severe acute
respiratory infection (SARI) activity also increased in a few countries (Germany and Spain). Rising cases of RSV infections were
reported in France. Pooled all-cause mortality estimates from the EuroMomo network showed elevated but decreasing excess
mortality across some age-groups.
