West Nile Story, Dickson Despommier

I came across this because I was trying out various science podcasts and tried listening to some of the early episodes of This Week in Virology (link goes to the episode about West Nile virus). I was curious to dig in a little more, and lo and behold, this book was on Kindle Unlimited. It discusses the earliest outbreak of West Nile virus in the US, which happened in New York during a hot, dry summer, and was somehow transmitted there from Israel. The podcast actually fleshes out the theory a bit more, while this book focuses on a wider look at the virus, its ecology and implications.

It’s probably a fairly dry read if you’re not interested in emerging infectious diseases, but since I am, I quite enjoyed it; I found it fairly simple, so if you’re just interested in diseases for the sake of it without a professional interest, I think it’s completely understandable for a layperson. It was a little basic for me at times, in fact.

Overall, it was a little scatterbrained somehow; it wandered off into discussing other diseases like malaria, without really tying it into the discussion of West Nile very well. I’d probably recommend the podcast over the book for that reason, but it was still interesting to dig in a bit deeper on some of the points mentioned in the podcast.

Sorting the Beef from the Bull, Nicola Temple & Richard Evershed

This book is about the science of food fraud — the way food fraud is committed, hidden, and detected. It has chapters on various staple foodstuffs, from meat (Horsegate, of course, but also other meat-related frauds like the injection of extra water into meat so that the consumer pays for water in the alleged weight), spices (you don’t want to know what happens with many ground spices), wine (mostly affecting rich people, but also some of the lowest end stuff), oil (olive oil is a big target), milk… Apparently it’s endemic in the UK, at least in Lancashire, that pizza takeaways almost universally do not use mozzarella — it’s not even cheese at all, with actual cheese only being added as a flavouring. And if you’re in the US, I have bad news about the likelihood that any red snapper is actually red snapper. 80% odds say it isn’t.

Most boggling to me, the idea that you can make a synthetic egg that fools people to the extent that they’ll crack the eggs, fry them up and consume them. (You can tell they aren’t real eggs because they lack a membrane inside the eggshell. That’s about it, to hear these authors tell it.)

It’s not just horror stories, of course: the authors also discuss the science at work in detecting these frauds, and the best ways for a consumer to avoid them. Mostly, it comes down to awareness, buying things whole (fish with the heads on; whole spices; recognisable cuts of meat, etc) buying seasonally, and buying locally from sources you can trust.

It’s all a bit horrifying, but fascinating as well. Definitely worth a read.

Return of the Black Death: The World’s Greatest Serial Killer,Susan Scott, Christopher J. Duncan

Full disclosure: I was sceptical before I even picked this up from the sensational title. You’ve got to go a seriously long way to convince me that the Plague is the “world’s greatest serial killer”, even if we accept that a disease should be considered in such an anthropomorphic light. Let me introduce you to your friendly neighbourhood Influenzavirus A, my #1 vote for “disease most likely to have the means to suddenly eradicate humanity”.

I picked it up because an author tweeted a thread of things she would never let anyone change her mind about, and one of the items was that she doesn’t believe the Black Death was caused by Yersinia pestis. Now, infectious disease is one of my special interests, and I already happened to know that Yersinia pestis has, for example, been isolated from plague pits. So I asked her for evidence of the claim, and she pointed me to this book.

Well.

From the start, it was not very rigorous or scientifically accurate? They’ve claimed that HIV is completely understood and under control and causes no panic, for one thing. (I wrote my dissertation on tuberculosis, so I can guarantee you that no HIV isn’t fully understood, because if we could, for example, understand how it and tuberculosis enable each other, that would be really helpful. We have theories, but as of a year ago, we don’t really know for sure.)

And then they make absurd statements like this: “…by all the rules of infectious diseases, when the Black Death was finished it should have disappeared.”

What?! Have they never heard of animal reservoirs? Re-introduction from the original sources? Endemic diseases? Fast-adapting diseases like influenza that change their surface proteins and thus evade immunity? Infectious diseases almost never just “disappear”, though there may be an outbreak in a new species due to chance contact that doesn’t reoccur that might look like disappearance.

What rules of infectious diseases can they possibly be referring to?

I mean, how many diseases do you even know of that have been driven extinct after much effort by humans doing so deliberately? That’ll be two: smallpox and rinderpest. (Smallpox is the only human disease to be eradicated, and with the aid of a highly effective vaccine and extremely persistent vaccination campaigns, it took 11 years of intense campaigning. We have so far been unable to repeat the effect on other target pathogens.)

And there’s this one: “[Measles] is not a danger to well-nourished children in the developed world.” Measles, which can kill (yes, even in the developed world), and furthermore wipes out your immune memory as well as depressing your innate immune system. And they think that Ebola literally liquefies your internal organs.

And then, you know, I read the immortal words stating that “it came as a great surprise to learn” that Iceland had effective contact with the rest of Europe in the 15th century, and also suffered two major outbreaks of the Black Death. Do they just… know nothing of history? At all? Clearly not: they also referred to a manuscript from 1404 as “ancient”…

I had more quibbles. Honestly, I was made out of quibbles about this book. I do have some lingering questions from good points they raised about the vectors, since they claim that rats/fleas of the type that could transmit bubonic plague were not present in Britain and certainly not in Iceland. It’s clear that their claim it was simply too cold in Britain for bubonic plague to survive is untrue, since studies since the publication of this book with reliable controls have found Yersinia pestis in plague pit remains in Britain, but that still makes me wonder about the vectors.

I’d also like to see independent verification of their work on the incubation period of the Plague, which according to their calculations aren’t at all like the modern Yersinia pestis (which is not genetically that different from the medieval version). However, the shakiness of their grasp on facts elsewhere leads me to doubt just about everything they say.

It’s All In Your Head, Suzanne O’Sullivan

The title of the book gives it away: this is a series of case studies, essentially, covering cases of psychosomatic disease. In it, as in O’Sullivan’s other book, she discusses the cases of various past patients and how she concluded their symptoms were not neurological disorders, but instead signs of a conversion disorder. I think the title is a bit of a disservice, because O’Sullivan is strongly against the kind of dismissal the phrase implies. She believes that (most of) her patients with this issue are truly distressed, truly experiencing pain and disability, and truly require medical help. Though it’s not a physical disorder of the nerves, it is something that should and must be treated in order to allow people to resume normal lives.

Understanding of psychosomatic illness and health anxiety is lacking in many doctors. Part of it is overwork: crowded clinics do not appreciate the sight of someone hoving into view with yet another anxiety-related illness of nebulous symptoms and solely psychological origin. But people like that, all the way along the scale from the lumps and bumps that trouble me to those whose brains paralyse themselves, all deserve compassion and treatment, and O’Sullivan’s book strongly advocates for that. She is firmly against the impulse to second guess a patient and assume they are faking.

That said, of course she makes herself come across as preternaturally patient with this kind of thing, and very sure about her diagnoses. She does discuss uncertainties now and then, but for the most part she is very certain of herself. Most of the cases she mentions are very clear-cut, and it makes it all seem very easy. In reality, things are muddier.

The chapter on ME/CFS has many detractors and as many people who shout that it is pure truth. Lacking the professional background or the academic reading on the topic, I can only say that I was under the impression that the graded exercise she recommends was in fact proven to be unhelpful, and that both sides in ME/CFS discussions can get very fraught and very disinclined to admit the truth of anything the other says. At the very least, O’Sullivan’s sympathy feels real, and she does intend to diminish the suffering of people with ME or CFS; she merely questions its source, and does not believe that a psychological source of issues means weakness or that you can just snap out of it.

It’s not deeply profound if you’re looking for the science of all this, though she does discuss what is known and the history of psychosomatic illnesses. It’s mostly of interest for really understanding the bananas things our brains can do to us. An enjoyable read, but not for me a groundbreaking one.
