In an escalating war between humans and microbes, catastrophic disease may have the edge. This program studies the ubiquitous threat posed by super viruses and describes scientific efforts to prepare for viral disease epidemics. Documenting the World Health Organization’s response to the 2005 Angolan Marburg virus outbreak, the program examines strengths and weaknesses in the WHO infrastructure. It also visits the Centers for Disease Control and Prevention in Atlanta, Rocky Mountain Laboratories in Montana, and Cornell University’s CHESS Synchrotron X-ray facility, featuring interviews with leading researchers who are developing sophisticated weapons against Ebola, dengue, HIV, and other viruses.
