A U.S. official praised the development. The moratorium "is a really good idea, because a lot of very important issues are at hand," said Dr. Anthony Fauci, director of the NIH's National Institute of Allergy and Infectious Diseases, who expects most flu researchers doing such work to sign on. "There aren't a lot of people who are doing that, I can assure you." The U.S. also wants international input; researchers are talking with the World Health Organization. Today, the so-called H5N1 bird flu only occasionally infects people, mostly those who have close contact with sick poultry. But when it does, it's highly lethal. The lab-bred H5N1 strains were a surprise because they showed it was easier than previously thought for the virus to mutate in a way that lets it spread easily between at least some mammals
-- in this case, ferrets.
