Spillover: Animal Infections and the Next Human Pandemic, David Quammen, WW Norton & Co.,2012; a Review

If you were perusing the library shelves and came across this book, the title “Spillover” may leave you a little uncertain in terms of its topic, without reading the subtitle and having some understanding of the processes described in the book, the emergence, evolution and ecology of ‘new’ diseases, human diseases. When we speak of them we understand them as conditions, assaults on our health and human bodies, which result in an array of symptoms, with wide ranging severity, ranging from mild and asymptomatic; to bothersome with knowable, short lived cycles; through chronic and debilitating; to those entailing a series of feverish cycles we simply must endure; to those often painful and fatal which wreck havoc on our systems and organs. Quammen, the author, is as always, an intelligent and thorough researcher able to interpret complex topics for the layman while staying true to the science and the people whose stories he tells as he weaves together the larger narrative.

COVID-19, Pandemics and How They Will Change the World For the Better

I’m not a biological ‘fatalist’, but there are several reasons why epidemiologists were attempting to plan for a pandemic and why the Obama administration was empowering institutions, creating protocols and organizing resources that could be mobilized quickly, before the COViD-19 outbreak, not for this one specifically, but one of some kind. Viruses, bacteria, mycoplasma and other microbes fill the world at a microscopic level…they are everywhere, all of the time. Our own bodies contain far more of them than we do of our own some three trillion cells. Fortunately, most of them do not cause us disease, at least as long as we remain healthy. Many of them, in fact perform valuable functions in us, beneficial ones, without which our lives would be the poorer. Disease too is part of life’s ‘plan’. Its agents are dynamic. Today’s diseases are not those of the past. We evolved together. They mutate and sometimes ‘leap’ across species boundaries. A study of biology and disease reveals a function of disease or at least a consequence to the health and evolution of a species. It may sound heartless to put it this way, but disease is very much a part of living. With this new disease, COVID-19, as with others, it is selective, affecting those whose health is compromised in some way disproportionately, killing those most susceptible, the weak and those may include those surprising to us. As in most things concerning life, nothing is so simple as our concept of strong and weak. Disease is a part of the process of natural selection that has always been in effect in the world.
