GP's advice on flu jabs and treatment
Flu cases have risen again in England and Wales, according to figures from GPs.
Levels of flu - including H1N1 swine flu - have gone up by almost 50% in the past week, says the Royal College of GPs.
The flu tally reached 124 per 100,000 people in the week to Christmas, up from 86 cases in the previous week.
GP Dr Alan Maguire spoke to the BBC's Fiona Trott to give some practical advice about vaccinations and what to do if you should fall ill.
