The figure for England is double the total of the previous week.
Some 840 people are described as being "seriously ill" in hospital with the illness - and 63 people are being treated in intensive care.
The death toll in the UK stands at 31, but that is likely to climb when the Department of Health releases its weekly update online later.
The shocking new figures come as the National Pandemic Flu Service opened across England, allowing people who think they have the H1N1 virus to bypass the NHS to obtain antiviral drugs.
The new phone hotline and website service use a checklist to diagnose cases and has been designed to relieve the pressure on the health service.
Swine Flu: Health Q & A
What is it? Could I catch it?
Your questions answered.
Visitors to the Government website are asked fill in a detailed questionnaire before being given a positive or negative swine flu diagnosis.
Call centre staff manning the telephone hotline - 0800 1513 100 - will use the same algorithm. They are expecting to field up to 200,000 queries a day.
If a caller is confirmed to have swine flu they will be given an authorisation number, which their designated "flu friend" can use to pick up antiviral drugs from the local collection point.
Over 2,000 staff have been recruited and given six-hour long training sessions before they start work. They are not required to have any previous medical experience.
Some critics claim the "worried well" will abuse the DIY diagnosis to apply for medication unnecessarily.
Others fear swine flu symptoms could mask other serious illnesses, like meningitis.
Seventeen-year-old Gemma Drury, from Chesterfield, was diagnosed with the H1N1 virus by two separate doctors.
She was in fact suffering from meningitis and is now recovering in hospital.
Her father Kevin told Sky News: "If two doctors could get it wrong with Gemma, what hope would someone on the end of the phone with no medical training have?
"It's not the right way to make a diagnosis."
The Department of Health insists the service is simply a way for people to get access to Tamiflu and other antiviral drugs quickly.
Anyone displaying unusual symptoms will still be advised to contact a medical professional.

This was all I needed, I've just spent four long years getting over SARS and now I catch this.
Typical.

People of my generation remember the Asian Flu epidemic.
The government of the time raised a campaign of awarenes with the slogan "coughs and sneeezes spread diseases - trap your germs in a handkerchief"
We should do the same again but with an one the spot fine for anyone sneezing in a public place without using a handkerchief. This would dramatically cut down the spread of the infection.

I'd make a valid comment if I could but I think I've got swine flu so I'm off to get some drugs.

People like you, Andrew, are as bad as the tabloids and press in scare-mongering this.
Jesus. Most of us probably won't get it. I've never even had normal flu, and I don't see myself catching swine flu... unless the filthy vermin who catch my train to work carry on breathing all over me.

Interesting to see that shortly after the government launched it's 'Pandemic Flu Service', I logged on to get advice. Only to be told that the website was 'very busy' and to return at a later time.
That is just typical of our government. As always they have not allowed for such interest and anticipated that the website would be subject to such demand.
We should rename it the ' Pandamonium Flu Service'.

All the people complaining about not getting a proper diagnosis should have a think about why it is being done this way!
If someone with Swine Flu walks into a doctors, usully full of pensioners, and it spreads, someone will die, if the doctor does a home visit, then carries the virus back to the doctors same problem.
I think it makes good sense to do it this way, if you haven't got swine flu and just normal flu, the tamiflu will only help!
Mexico should have been isolated as soon as it was caught, it could have been over and done with in two weeks! Now it will be atleast a year.
