MEXICO CITY (AP) - Mexico says the World Health Organization has
raised its pandemic alert for swine flu by one level, two steps short
of declaring a full-blown pandemic. WHO says the phase 4 alert is
defined as sustained human-to-human transmission causing outbreaks in
at least one country. It signals a significant increase in the risk of
a global epidemic, but doesn't mean a pandemic is inevitable. WHO has
confirmed human cases of swine flu in Mexico, the United States,
Canada and Spain.
