During the 20th century, more people died from viral infections than from all the wars around the globe. During the 21st, in a world where air travel can quickly transport a human virus host to any population concentration on Earth, runaway pandemics or bioterror attacks could easily exceed that number. This alarming two-part call to action uses true-to-life dramatizations, detailed 3-D animations, and commentary by virus specialists, WHO and CDC administrators, and other experts to analyze the continual mutation and proliferation of the most diverse group of life forms on the planet—and to propose steps that must be taken to thwart them. 2-part series, 52-53 minutes each.
