Carl Zimmer wrote these essays for the World of Viruses project as part of a Science Education Partnership Award (SEPA) from the National Center for Research Resources (NCRR) at the National Institutes of Health (NIH). World of Viruses was created to help people understand more about viruses and virology research through radio documentaries, graphic stories, teacher professional development, mobile phone and iPad applications, and other materials.
“In A Planet of Viruses, science writer Carl Zimmer accomplishes in a mere 100 pages what other authors struggle to do in 500: He reshapes our understanding of the hidden realities at the core of everyday existence.… Whether he’s exploring how viruses come to America or picking apart the surprisingly complicated common cold, Zimmer’s train of thought is concise and illuminating.”—Washington Post
