Did leak from a laboratory cause swine flu pandemic?

Same strain of influenza was released by accident (?) three decades ago

It has swept across the world killing at least 300 people and infecting thousands more. Yet the swine flu pandemic might not have happened had it not been for the accidental release of the same strain of influenza virus from a research laboratory in the late 1970s, according to a new study.

Scientists investigating the genetic make-up of flu viruses have concluded there is a high probability that the H1N1 strain of influenza “A” behind the current pandemic might never have been re-introduced into the human population were it not for an accidental leak from a laboratory working on the same strain in 1977.

Yesterday, the Department of Health announced a further surge in the number of cases in Britain with another 1,604 confirmed over the weekend, and the death of a girl in Birmingham with underlying medical complications; the third death in Britain from swine flu-related problems.
