I found this book fascinating. When I originally got it out of the library, some of my friends were a biiiit concerned that given my GAD was health-focused, this would just make me have a panic attack. I’m happy to report that I was simply happily curious, digging around with great enthusiasm, stopping to google things, etc.
In terms of the level this is at, it’s perfectly comprehensible to anyone, I would say. Granted, I do have a background in reading plenty of popular science, an A Level in biology, and various science/medical courses online, but I don’t think that puts me much above the layman, really. Where something needs explaining, Quammen does so quite clearly. (Although if you do find this fascinating but a bit dense for you, this course on Coursera might be worth a look the next time it runs. I enjoyed it, anyway.)
So, granted I already find this topic fascinating, but I think this was a good read. It avoided sensationalism, aside from the couple of chapters where Quammen imagined the life of the Cut Hunter from the cut-hunter theory of the origin of HIV, which were a little much for me. That goes beyond adding a bit of human interest into a flight of fancy, which jars with the rest of the book. If you want to think delightedly of Ebola victims as being a sack of liquefied matter, I gather you want to read The Hot Zone (Richard Preston).
It’s well-structured, taking us through various different zoonotic pathogens and their implications. The search for the “Next Big One” (the next pandemic) isn’t the primary focus, despite the title, and instead Quammen focuses on how the diseases are tracked, particularly how they are tracked to the reservoir species that safely harbour the pathogens until they spill over into other species. It’s not hysterical about the fact that there will be another pandemic, but treats it in a matter of fact way. Of course there’ll be another pandemic: we’re overcrowded, highly connected, highly social, and fairly careless.
I know there are people out there who will be complaining about Quammen’s bias when he notes that we are, to a great extent, making the problem worse. We destroy habitats, bring animals into closer contact with us, and thus bring ourselves into closer contact with their pathogens, which may spill over into humans. Not biased, and not hard to understand, just a fact.
