Flu: The Story of the Great Influenza Pandemic of 1918 and the Search for the Virus That Caused It : In 1918 the Great Flu Epidemic killed an estimated 40 million people virtually overnight. If such a plague returned today, taking a comparable percentage of the U.S. population with it, 1.5 million Americans would die. In Flu, Gina Kolata unravels the mystery of this lethal virus with the high drama of a great adventure story. From Alaska to Norway, from the streets of Hong Kong to the corridors of the White House, Kolata tracks the race to recover the live pathogen and probes the fear that has impelled government policy. A gripping work of science writing, Flu addresses the prospects for a great epidemic's recurrence and considers what can be done to prevent it.
