RaveThe AtlanticThree years after the outbreak of a devastating infectious disease with a staggering death toll, spending time with a book that vividly details the microbial richness of human history might not rank high on most people’s must-do lists. But those with enough of an epidemiological appetite to pick up Kennedy’s new book will be gratifyingly—if not necessarily cheerfully—rewarded with the knowledge that their read was at least well timed ... Kennedy’s book isn’t meant as revisionism; the broad strokes of history remain intact. But it gently sidelines humans—and, in doing so, humbles them ... ennedy’s book manages to end on a somewhat hopeful note. Yes, our trajectory is defined by microbes. But it’s also influenced by our reactions to them—and our acknowledgment of their power. This current pandemic may be tilting toward a slow end. As much as we may want the crisis to disappear in the rearview, the coda of one outbreak is an ideal time to prepare for the next, inevitably on its way.
