Emerging viruses2004

"Scientists have identified over 200 viruses, and an estimated 1,000 more may lurk undiscovered throughout the world. This program examines current scientific research on emerging viruses. Live-action microscopy shows the impact of the HIV virus on the human immune system. Sophisticated animation depicting viral life cycles reinforces the concept that the best defense against dangerous viruses may well be a more complete understanding of how they work."--Container.
