UK 'in grip of worst flu season since 2011' - BBC News

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.
