Swine flu could hit one in every three people
The number of confirmed swine flu cases across 30 countries around the world has broken the 5,000 mark with 61 having died from the disease. Studies suggests swine flu could kill four in every 1,000 infected people.
Professor Neil Ferguson of the World Health Organisation's emergency committee for the outbreak, told the BBC Radio 4 Today programme: "This virus really does have full pandemic potential. It is likely to spread around the world in the next six to nine months and when it does so it will affect about one-third of the world's population...
"We really need to be prepared, particularly for the autumn. At the moment, the virus is not spreading fast in the northern hemisphere, because we are outside the normal flu season, but come the autumn it is likely to cause a really major epidemic."
