This section contains information provided by the HPA South West. Influenza and influenza-like illness (ILI) result in
increased activity in the health service. In 2009/10 there was a pandemic of a new influenza virus, H1N1v (Swine Flu).
GP Consultation Rates for Influenza-like Illness
8.5.1.1 GP consultation rates for influenza-like illness in the UK and South West from week 14 in 2009 (30th March to 5th April) to week 13 in 2010 (29th March to 4th April) showed a peak in the summer weeks 28 to 32 (6th July to 9th August 2009) which exceeded normal seasonal activity (20 to 70 per 100,000 population): this was due to swine flu. The highest UK peak was 225.6 per 100,000 in week 30 (20th to 26th July 2009), and the highest South West peak, also in week 30, was 218 per 100,000 (Figure 8.5.1.1).There was also a smaller peak over baseline levels (over 20 per 100,000 population) during the winter weeks.

8.5.1.2 Uptake of the flu vaccine remains low. Seasonal flu uptake percentages in persons aged 65 years and over for 2009/10 for the Primary Care Trusts in the South West, the South West as a whole, and for England as a whole are shown in Figure 8.5.1.2. Nationally, vaccine uptake for people aged 65 years and over was 72.4%, a decrease compared with 74.1% during the 2008/09 season. Uptake for the South West for 2009/10 was similar to the national figure at 72.9%.
