How do we fight both the swine flu pandemic and our fear of it? NOW's David Brancaccio sits down with one of the most prominent figures in world health to find out. Dr. Larry Brilliant is an epidemiologist, former chief philanthropist at Google.org, and was a central figure in the World Health Organization's successful small pox eradication program. The two discuss how high tech tools are making it easier for scientists to detect global outbreaks, the critical importance of early detection and early response, and how the current pandemic has yet to show its real hand. "Anyone who tells you that they know that this is a mild pandemic, and the WHO has overreacted, they don't know. Anyone who tells you that the WHO and CDC have underestimated it, they don't know," Brilliant tells NOW. "We're all going to find out at the same time...we're all in it together." The show also features vital insight from Dr. Nathan Wolfe, a Stanford University epidemiologist who specializes in hunting viruses to their source.
