Swine flu infected at least 100,000 Britons last week, officials announced on Thursday.
Sir Liam Donaldson, the Chief Medical Officer, said there were now 840 patients in hospital in England with swine flu, 63 of them in intensive care.
Children are being hit hardest, with relatively few cases amongst the elderly, as it is thought they may have some immunity to the H1N1 virus from previous pandemics.
