2020-2021 season overview
- For the Region as a whole, influenza activity has been at baseline level since the start of the season
- In total, 80 specimens have tested positive for influenza viruses, 1 from sentinel sources and 79 from non-sentinel sources, with A(H1)pdm09, A(H3) and type B viruses detected.
- No cases of hospitalization due to influenza virus infection have been reported.
- WHO has published recommendations for the composition of influenza vaccines to be used in the 2020–2021 northern hemisphere season. Based on these recommendations, the influenza A(H1N1)pdm09, A(H3N2) and B/Victoria-lineage virus components should be updated compared to the 2019–2020 influenza vaccine.
As of week 47/2020, for the European Region, influenza virus positivity in sentinel specimens remained below the epidemic threshold, which is set at 10%.
Mortality monitoring: Overall pooled estimates of all-cause mortality for 26 countries and areas participating in the EuroMOMO project showed substantially increased excess mortality, coinciding with a reported increase in COVID-19 cases in several countries.
The excess all-cause mortality was seen primarily in the 45 years and above age groups.
