WHO sends 2.4 million Tamiflu courses to poorer nations

The World Health Organization said Saturday that it sent 2.4 million treatments of anti-flu drug Tamiflu to 72 developing countries preparing themselves against a possible swine flu pandemic. WHO's global alert and response director said "at this point it's important that all countries have access to antivirals." Dr. Mike Ryan said the drugs came from a WHO stockpile donated by drugmaker Roche Holding AG, though he did not name the recipients. Ryan also said WHO was not yet raising its alert to a full pandemic as the virus has yet to cause sustained transmission outside of North America. WHO upped its tally of confirmed human cases earlier Saturday to 615, with 17 deaths. The rise largely reflected recent confirmation of older cases in Mexico, the epicenter of the outbreak.
