A virus common in birds could have widespread and fatal consequences for humans. That's according to the World Health Organization which recently announced an avian flu pandemic would be "very, very likely" in the next few years. Recent reports have found that the virus has jumped from birds to humans. Scientists worry that if the virus takes on a form that can be communicated between humans, a pandemic on the order of the deadly 1918 outbreak could be close at hand. Host Steve Curwood talks with Dr. Anthony Fauci of the National Institutes of Health about how the U.S. might protect against an impending pandemic.
