Maryn McKenna is the prize-winning former science writer for theAJC who won awards for her coverage of the CDC.  She returns to the Library with a frightening but true new book, Superbug: The Fatal Menace of MRSA. MRSA is a terrifying pathogen that is evolving faster than the medical community can develop antibiotics to stop it, and it is now beginning to threaten not just hospitals and clinics but individuals young and old, healthy and sick. McKenna is also a former Fellow at the University of Michigan and Harvard Medical School and the author of Beating Back the Devil: On the Front Lines with the Disease Detectives of the Epidemic Intelligence Service.  She joined us on April 27th, 2010.
