Swine flu infects 100,000 in one week
This is around double the number in the previous week, when 55,000 people were estimated to be newly-diagnosed with swine flu in England.
It comes as the National Flu Pandemic Service for England website crashed within minutes of going live due to the volume of people trying to access it. The service allows diagnosis and the prescription of drugs over the internet or by telephone. There are now 840 people in hospital with the virus, of which 63 are in intensive care.
