Before Ebola there was bird flu. After Ebola there will be bird flu. The question is not whether but when. If you think a deadly disease passed by body fluids is scary, wait until you encounter one that infects by the simple and necessary act of breathing. The last time avian flu unleashed a plague on humankind, it killed over 50 million people. And it did not, and will not, spare America. The hurdles we face in protecting ourselves, as this glimpse of Ebola tells us, will be enormous. Welcome to the world of Virion, a gripping story of man versus virus. From the gleaming laboratories of the United States to the steamy deltas of Southeast Asia, the microbe taunts global experts to predict its behavior, just as the current outbreak of Ebola does. Drs. Ken Culp and Lou Symington set international leaders on a collision course as they race against time and each other to prevent an epidemic that will kill millions. Everyone fears the destructive virus, but the real threat may be the arrogance of man.
