Weekly influenza surveillance overview January 7, 2011 - Week 52
Generally, reporting of influenza has been less complete over weeks 51 and 52 due to the holiday period, which reduces consulting rates and reporting to national centres and subsequently onto ECDC. Nevertheless, in week 52/2010, 15 of the 25 countries reported increasing trends of influenza activity.
After little change in week 51/2010, the percentage of sentinel specimens that tested positive for influenza rose to 46% in week 52/2010, indicating rising intensity. For combined sentinel and non-sentinel influenza positive specimens, 73% were type A and 27% were type B. Ninety-eight percent of sub-typed influenza A viruses were A(H1N1) 2009.
In week 52/2010 six countries reported 56 SARI cases, of which 22 were known to have been infected by the A(H1N1) 2009 virus.
During week 52/2011 (26 Dec 2011 - 1 Jan 2012) the annual seasonal influenza began in some countries in Europe though intensity remains low as yet in all countries reporting.
Of 380 sentinel specimens collected during week 52/2011, 23.4% tested positive for influenza viruses, more than double the percentage reported in week 51. This influenza season is characterised by the dominance of A(H3N2) viruses though A(H1N1)pdm09 viruses are significant among the severe cases reported. Further information can be found in ECDC’s Weekly influenza surveillance overview and the the ECDC/CNRL Report on Influenza virus characterisation, December 2011.
To date most viruses detected have been of the A(H3) type with only a few of the A(H1)pdm09 type from the pandemic although they remain a significant number of the severe cases reported. The match with the current vaccine strains is reasonable and though the numbers tested are limited there is little indication of antiviral resistance to oseltamivir or zanamivir.
In addition, following reports of a human fatality due to avian influenza (A(H5N1)) in China’s Guangdong province, the European Commission requested an assessment of risk of human-to-human transmission. ECDC does not consider there is any change to the previous assessments that the risk for EU/EEA countries is very low.
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).
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).
