Even as you read this, your body is under attack. Your enemy is patient, adaptable, potentially deadly, and invisible. Called the “littlest assassin” and “phantom killer,” viruses range from the common cold to HIV, and have caused epidemics of disease more decimating than war or natural disaster. “Understanding: Viruses” explains how these submicroscopic parasites operate, and how your immune system works to defend you. And you’ll see what scientists are up to in this never-ending battle, including radical new attempts to use invading viruses as agents of healing.
