First swine flu death in U.S.
GENEVA, Switzerland (CNN) -- The World Health Organization raised its pandemic alert to 5, its second-highest level Wednesday, indicating the outbreak of swine flu that originated in Mexico is nearing widespread human infection.

"This change to a higher phase of alert is a signal to governments, to ministries of health and other ministries, to the pharm industry and the business community that certain actions now should be taken with increased urgency and at an accelerated pace," Chan said. The annoucement came as the number of people infected with swine flu increased rapidly across the world, and health officials scrambled to get more information about the virus -- which has no vaccine.
