H1N1 virus 'now unstoppable'Swine flu becomes first pandemic in 41 years
The World Health Organization told its member nations it was declaring a swine flu pandemic Thursday — the first global flu epidemic in 41 years — as infections climbed in the United States, Europe, Australia, South America and elsewhere. U.S. officials said today they've taken an early aggressive approach and the WHO announcement won't change how it's been dealing with the issue. The WHO designation is based on geographic spread and not on the nature of the disease, U.S. officials said.
