Mexico Swine Flu Deaths Spur Global Epidemic Fears

"MEXICO CITY (AP) -- 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 U.S."

"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 article continued that, "The geographical spread of the outbreaks also concerned the WHO - while 13 of the 20 deaths were in Mexico City, the rest were spread across Mexico - four in central San Luis Potosi, two up near the U.S. border in Baja California, and one in southern Oaxaca state.

Scientists have long been concerned that a new flu virus could launch a worldwide pandemic of a killer disease. A new virus could evolve when different flu viruses infect a pig, a person or a bird, mingling their genetic material. The resulting hybrid could spread quickly because people would have no natural defenses against it.

Still, flu experts were concerned but not alarmed about the latest outbreak.

'We've seen swine influenza in humans over the past several years, and in most cases, it's come from direct pig contact. This seems to be different,' said Dr. Arnold Monto, a flu expert with the University of Michigan.

'I think we need to be careful and not apprehensive, but certainly paying attention to new developments as they proceed.'

The CDC says two flu drugs, Tamiflu and Relenza, seem effective against the new strain. Roche, the maker of Tamiflu, said the company is prepared to immediately deploy a stockpile of the drug if requested."

It concluded with, "It's unclear how the eight, who became ill between late March and mid-April, contracted the virus because none were in contact with pigs, which is how people usually catch swine flu. And only a few were in contact with each other.

CDC officials described the virus as having a unique combination of gene segments not seen before in people or pigs. The bug contains human virus, avian virus from North America and pig viruses from North America, Europe and Asia. It may be completely new, or it may have been around for a while and was only detected now through improved testing and surveillance, CDC officials said.

The most notorious flu pandemic is thought to have killed at least 40 million people worldwide in 1918-19. Two other, less deadly flu pandemics struck in 1957 and 1968"
