U.S. Centers for Disease Control and Prevention director Dr. Julie Gerberding says bird flu fatigue among countries and the public is a growing concern.
Scientists have identified the H5N1 bird flu virus as a potential candidate that could mutate into a form that spreads easily among people.
"People have very short attention spans and when something is in the news for a while, it becomes old news and then it's no news," she said at a conference Saturday. "We have to be very strategic to make sure that the leaders and governments fill in for the tendency toward complacency."
