CDC said that it has developed an improved polymerase chain reaction assay to detect the virus and will soon send it out to a network of 140 laboratories that work with the agency. CDC also has a team in Mexico assisting health officials there.

"If there's any appearance that things are not available to people, it's mainly because it's a new virus. We are making the reagents for it, and it's just a matter of time for us to get them out," said Daniel Jernigan, a medical epidemiologist in the influenza division. Dr. Jernigan added that CDC anticipates that those reagents will be available very soon.

Meanwhile, New York City is looking into possible swine flu cases, and the WHO has decided not to raise its pandemic threat level, although it did call the situation a "public health emergency of international concern."
