直近の過小評価に注意
In Europe, overall influenza activity continued to increase with influenza positivity from sentinel sites increasing to 23%, above the 10% epidemic
threshold. Both Influenza A and B viruses were detected with influenza A(H3N2) predominating among the subtyped viruses across sentinel sites and
A(H1N1)pdm09 predominating among non-sentinel sites. Six countries reported high/very high influenza intensity and 16 countries reported
widespread activity. Positivity was highest in Eastern Europe, above 19%. Influenza detections increased in the subregion, across both sentinel and
non-sentinel sites, mostly due to A(H1N1pdm09) virus detections in the Russian Federation but also increased influenza detections in Czechia and
Ukraine. The Russian Federation, Poland, Czechia, Hungary, Republic of Moldova and Slovakia reported increases in ILI and influenza-associated
hospitalizations continued to increase sharply in the Russian Federation. In Northern Europe, activity continued to increase, but less steeply relative
to the rest of the region. A similar proportion of influenza A(H3N2) and A(H1N1)pdm09 was detected among the subtyped A viruses except in a few
countries where A(H1N1)pdm09 predominated (Iceland, Ireland, Latvia and Northern Ireland). ILI increased in Estonia, Finland, Iceland, Ireland,
Latvia and Lithuania. In Southwest Europe, influenza detections of predominantly A(H3N2) continued to increase in some countries, especially in
France, Germany, Italy and Switzerland while a decrease in detections was reported in Portugal and Spain. ILI activity increased to medium/moderate
activity in Belgium and France. Increases were also observed in Greece, the Netherlands and Switzerland. ILI activity stabilized in Italy but remained
at high intensity. A fluctuation/decrease in ILI activity was observed in Luxembourg and Portugal. SARI activity remained elevated in Germany, Serbia
and Spain, and also continued to increase in Croatia. Overall, 17 countries reported SARI cases, of which 21% of tested specimens were positive for
influenza. This is higher than the percentage positive for SARS-CoV-2 (2%) among SARI cases. The vast majority (82%) were influenza A viruses.
RSV positivity decreased to expected levels for this time of year. Bronchiolitis continues to be reported at high levels in
88
France but has decreased. Pooled all-cause mortality estimates from the EuroMomo network showed elevated but
88
decreasing excess mortality across some age-groups.
