The UK is in the grip of its worst flu season for seven years, figures show. All parts of the UK have seen rises in suspected flu cases since the turn of the year with Wales seeing the sharpest – close to a fourfold increase in GP visits to 64.9 cases per 100,000. The last time there was more flu circulating than this was in 2010-11 when swine flu, responsible for the pandemic of the year before, came back.
Hospitals are also seeing “very high” rates of admissions, officials said. However, it appears the strain known as Aussie flu is not causing the most serious illnesses, according to the weekly report up to last Sunday from Public Health England.
Instead – of the four strains circulating – a B strain, which does not normally cause high rates of severe illness, is responsible for about half the hospital cases.
