The Spillover Switch: One Mutation, A World of Difference
How Coronaviruses Learn to Infect New Species

About this book:

From the shadowy depths of bat caves to the global stage of a pandemic, *The Spillover Switch* reveals the terrifying elegance of viral evolution. This gripping scientific detective story pulls back the curtain on the molecular machinery—spike proteins, ACE2 receptors, and the infamous furin cleavage site—that allows a microscopic pathogen to rewrite its own destiny and ours. You’ll witness how a single, random mutation can transform a harmless resident of a winged mammal into a global threat, turning a key in a lock that was never meant to be opened.

Journey deep into the "silent reservoir" where coronaviruses have honed their craft for millennia, mastering the art of the species jump. With the pacing of a thriller and the precision of a laboratory report, the book dissects the anatomy of spillover: the evolutionary pressures, the intermediate hosts, and the controversial laboratory experiments that recreate these leaps in real-time. It connects the dots between bat immunology, human encroachment, and the genetic evidence that writes the history of every outbreak in viral RNA.

More than a post-mortem of the past, this is a roadmap for the future. *The Spillover Switch* arms you with the knowledge to understand the next headline before it breaks, exploring the cutting edge of viral surveillance, One Health strategies, and the ethical frontiers of gain-of-function research. Essential reading for anyone who wants to understand not just how the last pandemic started, but how we can flip the switch on the next one.
