- Up until 19 January 2011, 254 fatal influenza cases from across the UK were reported to the HPA, including 165 cases from England.
- Further epidemiological information on cases is available on 214 of these cases.
- One hundred and ninety-five (91%) of these cases were associated with H1N1 (2009) infection, three with untyped influenza A and 16 (7%) with influenza B infection.
- Reported deaths have been mainly in younger adults and children.
- Among the 210 cases with information on age, seven (3%) have been younger than 5 years, 11 (5%) in the 5?14 year age group, 137 (65%) from 15 to 64 years and 55 (26%) were older than 64 years of age.
- One hundred and twenty-eight of 159 fatal cases with available information (81%) were in one of the clinical risk groups for vaccination, which includes pregnant women.
- The leading reported clinical risk factors for those with information were underlying respiratory disease, including asthma (n=29) and neurological disease (n=15).
- Conversely, 19% of the deaths were in healthy people outside these risk groups (click here for report).
