Virus hunters chase down the swine flu

The world has found a new strain of flu, so now what? Enter the virus hunters. This pack of epidemiologists, virologists, and infectious disease experts (sounds like a fun party) are fast on the bug’s tail, looking for answers that may help us control its spread. What are they trying to figure out? How long will it take to rustle up some answers? And when you’re an epidemiologist chasing down a flu virus, what do you do in your lab all day? The Takeaway is joined by Dr. Susan P. Fisher-Hoch, an epidemiologist at the University of Texas School of Public Health and co-author of the book, Level 4: Virus Hunters of the CDC.
