Weekly influenza surveillance overview, March 23, 2012 - Week 11
The weekly/bi-weekly influenza surveillance overview is a collection of timely and relevant information regarding influenza activity in Europe. It provides key statistical data on a variety of issues including the following: sentinel surveillance of influenza-like illness (ILI) and acute respiratory illness (ARI); virological surveillance; hospital surveillance of severe acute respiratory infection (SARI); mortality surveillance and qualitative reporting. An up-to-date report is available on Fridays.
The 2011–2012 influenza season started late and has been without any clear geographic progression. During week 11/2012, medium intensity was reported in 16 countries, high intensity in one country, and decreasing trends in 15 countries. Of those, 8 countries reported decreasing trends for two consecutive weeks, suggesting that their influenza seasons have peaked.
Virological surveillance for the period shows that out of 1 203 sentinel specimens tested, 502 (41.7%) were positive for influenza virus. The proportion of sentinel specimens testing positive for influenza virus has decreased over three consecutive weeks. Of the sentinel specimens that tested positive for influenza virus 82.9% were type A and 17.1% type B.
There has been a degree of heterogeneity in the antigenicity of the A(H3) viruses this season and an imperfect fit with the A(H3) component in the seasonal vaccine.
As often observed late in the season, the proportion of influenza B viruses among the detected influenza viruses has been increasing and has doubled over the past two weeks.
Since week 40/2011, a total of 1 378 SARI cases, including 69 fatalities, have been reported by seven countries. Of these cases, most were influenza-related.
No resistance to neuraminidase inhibitors (oseltamivir and zanamivir) has been reported so far this season.
Influenza virus characterisation, December 2019
16 Jan 2020 - This is the third report for the 2019–20 influenza season. As of week 1/2020, 42 844 influenza detections had been reported across the WHO European Region; 85% type A viruses, with A(H3N2) prevailing over A(H1N1)pdm09, and 15% type B viruses, with 531 (92%) of 576 ascribed to a B/Victoria lineage.
Monthly measles and rubella monitoring report, January 2020
10 Jan 2020 - The monitoring report is based on measles and rubella data from The European Surveillance System (TESSy) for the period 1 December 2018 to 30 November 2019.
Surveillance report: Avian influenza overview August – November 2019
20 Dec 2019 - This scientific report provides an overview of highly pathogenic avian influenza (HPAI) virus outbreaks detected in poultry, captive and wild birds and noteworthy outbreaks of low pathogenic avian influenza (LPAI) virus in poultry and captive birds, as well as human cases due to avian influenza (AI) virus, reported in and outside Europe between 16 August and 15 November 2019.
