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, summary Europe, June 2019
15 Jul 2019 - This is the eighth report for the 2018–19 influenza season. As of week 25/2019, 205 167 influenza detections across the WHO European Region had been reported. Detections were 98.9% type A viruses, with A(H1N1)pdm09 prevailing over A(H3N2), and 1.1% type B viruses, with 85 (58%) of 146 ascribed to a lineage being B/Yamagata-lineage.
Tularaemia Annual Epidemiological Report for 2017
15 Jul 2019 - For 2017, 447 cases of tularaemia were reported by 18 countries in the EU/EEA, 413 (92%) of which were confirmed. As in previous years, the proportion of cases among males was higher in all age groups, with a male-to-female ratio of 2.1:1. Notification rates in men and women increased with age (except for the age group ≥65 years). The highest rate was observed in men in the age group 45–64 years (0.2 cases per 100 000 population).
Hantavirus infection - Annual Epidemiological Report for 2017
15 Jul 2019 - In 2017, 21 countries reported 4 239 cases of hantavirus infection (0.8 cases per 100 000 population). Two countries, Finland and Germany, accounted for 70.1% of all reported cases. In the absence of a licensed vaccine, prevention mainly relies on rodent control, avoidance of contact and properly cleaning and disinfecting areas contaminated by rodent excreta (urine, saliva or droppings).
