Mexico swine flu deaths spur global epidemic fears

MEXICO CITY – A unique strain of swine flu is the suspected killer of dozens of people in Mexico, where authorities closed schools, museums, libraries and theaters in the capital on Friday to try to contain an outbreak that has spurred concerns of a global flu epidemic.

The worrisome new virus — which combines genetic material from pigs, birds and humans in a way researchers have not seen before — also sickened at least eight people in Texas and California, though there have been no deaths in the US.

"We are very, very concerned," World Health Organization spokesman Thomas Abraham said. "We have what appears to be a novel virus and it has spread from human to human ... It's all hands on deck at the moment."

The outbreak caused alarm in Mexico, where more than 1,000 people have been sickened. Residents of the capital donned surgical masks and authorities ordered the most sweeping shutdown of public gathering places in a quarter century. President Felipe Calderon met with his Cabinet Friday to coordinate Mexico's response.

The WHO was convening an expert panel to consider whether to raise the pandemic alert level or issue travel advisories.

It might already be too late to contain the outbreak, a prominent US pandemic flu expert said late Friday.

Given how quickly flu can spread around the globe, if these are the first signs of a pandemic, then there are probably cases incubating around the world already, said Dr. Michael Osterholm at the University of Minnesota.

In Mexico City, "literally hundreds and thousands of travelers come in and out every day," Osterholm said. "You'd have to believe there's been more unrecognized transmission that's occurred."

There is no vaccine that specifically protects against swine flu, and it was unclear how much protection current human flu vaccines might offer. A "seed stock" genetically matched to the new swine flu virus has been created by the US Centers for Disease Control, said Dr. Richard Besser, the agency's acting director. If the government decides vaccine production is necessary, manufacturers would need that stock to get started.
