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.
Almost 6,000 Britons have now been infected with the influenza “A” (H1N1) strain of swine flu. But two medical researchers believe that this strain of the virus had been extinct in the human population for more than 20 years until it was unwittingly reintroduced by scientists working in a research lab somewhere in the world, leading to a pandemic in 1977 that began in Russia and China.
