The World Health Organization (WHO) announces a donation from Swiss drug maker, Roche, of enough of its Tamiflu antiviral to treat 3-million people infected with the avian flu.

WHO Director-General Lee Jong-wook says, "If a flu pandemic were to emerge, these drugs could be flown quickly to the center of a potential pandemic. If it hits, and we are unprepared, there will be millions and millions of deaths."

The WHO says it is watching the outbreaks because all had the potential to trigger a global pandemic if the virus mutates and becomes easily transmittable between humans.
