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.

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.
