menu Swine-Flu Warning Raised as Virus Crosses Continents

The World Health Organization, acknowledging the growing threat of swine flu, raised its global pandemic alert, saying the disease is no longer containable.

The alarm level, increased to 4 from 3, is at its highest since the warning system was adopted in 2005, and the virus has been confirmed in the U.K., Mexico, the U.S., Canada, New Zealand and Spain. The emphasis worldwide should be on treating patients and strengthening preparations for outbreaks, said Keiji Fukuda, assistant director-general for health security and environment.
