Why Revive a Deadly Flu Virus? - New York Times: "The 1918 flu virus is remarkable for two reasons. First, it caused perhaps the most lethal plague in the history of humankind. In the fall of that year it spread across the planet, perversely striking down healthy young adults. Once ensconced in their lungs, the virus triggered a havoc of inflammation, hemorrhage and cell death. Trying to draw air into such lungs was like breathing through meat. Many of the afflicted died within hours after they first began to feel a little feverish. Others succumbed more slowly to secondary bacterial infections. By the spring of the following year, the virus had disappeared as mysteriously as it had come."
