World Health OrganizationNearly 5,000 people have reportedly died from swine flu since it emerged this year and developed into a global epidemic, the World Health Organization said Friday.

Since most countries have stopped counting individual swine flu cases, the figure is considered an underestimate.

WHO said there were 4,999 total deaths through Oct. 18, most of them in the Western Hemisphere. The figure was up 264 from a week earlier.
