During week 52, 23 patients infected with influenza A (H1N1) in 2009 notified under the Infectious Diseases Act, which is double the figure for the previous week. Since the start of the season in week 40, with 65 cases of A (H1N1) reported in 2009. A large proportion of patients (46 pc) were not vaccinated against the influenza pandemic, 16 were missing data on vaccination status and only three patients reported that they were vaccinated. The metropolitan regions of Stockholm and Malmö are now the majority of the cases reported. Although the maximum number of ill is in the 15-64 age group the incidence rate (the proportion of disease per 100 000 population), as last year more than bumps in the age 0-5 years. However, so far, the proportion reported among children less than last year. To date, a total of 21 patients received care hospitals of which five have had such severe symptoms that required intensive care.
Although the number of influenza A and B diagnoses reported by the voluntary laboratory reporting has increased over 51 weeks compared with last week. A total of 36 influenza A and B reported (14 A and 22 B) from five counties, including Stockholm and Västra Götaland which have reported the most cases.
Under the sentinel samples of influenza, a bit fewer samples received during week 51, probably due to Christmas holidays are. Among the 24 samples tested showed a influenza A and influenza B. All samples from the previous week is now fully analyzed. Among the 50 samples received that week, six influenza B and influenza A. All samples were taken in Stockholm, but one of the influenza B-positive samples came from Halland.
As part of sentinel surveillance of clinical influenza symptoms (ILS) has only a few districts surgeries submitted reports in week 51 due to Christmas holidays and we can therefore expect a degree of reporting in the coming weeks. Total notified Fourteen subjects with influenza-like symptoms this week from five counties, Gävleborg, Jämtland, Stockholm, Värmland and Västerbotten.

According influenza network EuroFlu, the proportion of positive influenza tests increased significantly in week 50 and nearly doubled since the previous week. On average, the proportion of positive samples around 39% but the proportion varied significantly between member countries. Belgium and the UK accounted for the highest positive rate, where 62% respectively. 60% of all respiratory samples were positive for influenza.
The overall picture of the European influenza surveillance by the WHO provides is that in most countries in the region where influenza activity remained relatively low during the reporting period. During week 50 reported in particular Belgium, Ireland, Portugal and the UK an increasing influenza activity, while Finland, France, Italy and Norway only reported some regional distribution. Hungary is the only country indicated by a downward trend in influenza.
Several recent outbreaks of influenza A (H1N1) in 2009 and influenza B have been reported from the UK (England) which have brought great pressure on intensive care units. All influenza viruses characterized to date have likened the strains included in this year's seasonal influenza vaccine.
