WHO Raises Pandemic Flu Alert Level to Phase 4

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.

Mexico health department spokesman Carlos Olmos confirms the move.

WHO says the phase 4 alert means 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.
