Virus X: Tracking the New Killer Plagues—Out of the Present and into the Future

of Fischer-Hoch's first-hand descriptions of the pathogenic virology laboratories in Britain and in China, the experiences she accounts were also witnessed by McCormick, and it seems as though the addition of the chapters authored by Fischer-Hoch was an afterthought. But the back-and-forth alternation of these two voices gives the work a conversational feeling, and although somewhat disorganized, is an interesting and engaging style. Level 4 does not attempt to be a textbook or a research report, but rather a collection of extraordinary stories from the remarkable lives of two "virus hunters." As such, it can be enjoyed by lay persons and medical scientists alike and should be able to ride the wave of popular interest in this genre.
