CDC: Swine flu viruses in U.S. and Mexico match

U.S. health officials expressed concern Friday that a swine flu virus that has infected eight people in the United States matches samples of a virus that has killed at least 68 people in Mexico.

Swine flu is usually diagnosed only in pigs or people in regular contact with them.

As a precaution to avoid further contamination, schools and universities in Mexico City and the state of Mexico were closed Friday, said the national health secretary, Jose Angel Cordova Villalobos. He said the schools may remain closed for a while.

The new virus has genes from North American swine and avian influenza, human influenza, and swine influenza normally found in Asia and Europe, said Nancy Cox, chief of the CDC's Influenza Division.

A pandemic is defined as: a new virus to which everybody is susceptible; the ability to readily spread from person to person; and the capability of causing significant disease in humans, said Dr. Jay Steinberg, an infectious disease specialist at Emory University Hospital Midtown in Atlanta. The new strain of swine flu meets only one of the criteria: novelty.

All I can say is that this is an unexpected illness, so we have to be careful because it can cause the death. For the time being, """""there no class tomorrow""""" ( Mr. Ruben words) yeahhhh¡¡¡
