Global flu epidemic fear grows

A new flu that has killed up to 68 people in Mexico could start a global epidemic, the World Health Organization warned on Saturday, as tests showed the strain might be spreading in the United States.

Mexico’s crowded capital, where most of the deaths happened and home to some 20 million people, hunkered down in fear of the swine flu.
The new flu strain — a mixture of swine, human and avian flu viruses — is still poorly understood.
