In week 5/2011 the number of patients in England with confirmed or suspected influenza in critical care beds have declined from a peak of nearly 800 three weeks ago (equivalent to 1.4 per 105 population) to around 160 cases on 3 February.
Over 80% of these are in the age group 16 to 64 years.
Up to 2 February 2011, 395 deaths have been reported in influenza cases from across the UK.
Ninety-two percent of the 214 cases were associated with A(H1N1)2009, 2% with untyped influenza A and 6% with influenza B infection.
Reported deaths associated with influenza have been mainly in younger adults and children.
Amongst cases with information on age, 3% have been less than five years; 4% between five and 14 years; 72% from 15 to 64 years and 21% were 65 years or older.
Of those with available information, 73% were in one of the clinical risk groups where vaccination is recommended, which includes pregnant women.
Important reported clinical risk factors were underlying respiratory disease including asthma (27% of those in the clinical risk groups) and immunosuppression (23%).
Of cases with information on immunisation history, 72% had not received the 2010 trivalent vaccine and 95% had not received the monovalent pandemic vaccine last season.
All-cause all-age deaths (due to multiple causes, not just influenza) declined in week 3/2011, although it remained above the upper limit of expected levels for this time of year.
