Oh, how I remember 2003 when the Toronto region, where I live, became the continent’s epicenter for an illness called severe acute respiratory syndrome (SARS). My mother was nearing life’s end and we were in and out of the hospital, always subjected to rigorous protocols involving screening, wearing flimsy gowns and uncomfortable masks, obligatory application of germicides, and still experiencing the “what if” fear that it might not be enough to protect us from this mysterious illness which ultimately led to 43 deaths (out of 438 probable cases), mostly in my region. It’s no wonder that there is such high concern about the emergence of the Wuhan coronavirus, now, at the time of writing, detected in 15 countries.
It appears that both these diseases, unsettling for their virulence and contagiousness, originated in China’s wild animal markets. Chinese authorities have “temporarily” banned trade in wild animals, but now is too late. Why did the SARS epidemic not teach a lesson? I can’t express myself more succinctly than a PBS Newshour report that stated: “Demand for wild animals in Asia, especially China, is hastening the extinction of many species, on top of posing a perennial health threat that authorities have failed to fully address despite growing risks of a global pandemic.”
The origin of human immunodeficiency virus (HIV), which can lead to full-blown acquired immune deficiency syndrome (AIDS) has also been traced back to animal origins, in that case Africa, and to the similar simian immunodeficiency virus (SIV) that can be found in some of our fellow primates – the apes, in this case chimpanzees. Exposure also occurred through consumption of the wild animals. The Ebola virus first entered the human population in the Congo, causing quick, horrific death to well over a thousand people. The origin? Wild animals, chimps again, and/or bats.
I am not a germaphobe, and, in fact, I ascribe to the theory that we are healthier if we avoid seeking a sterilized, cleanly scrubbed, impossible-to-achieve germ-free existence, which can compromise the immune system’s development.
My interest in this topic, apart from the fears and inconvenience experienced during the local SARS outbreak, derive from the fact that I contracted equine encephalitis as a teenager (with increasingly mild but unpleasant relapses ever since) and that I have, myself, been in close contact with a wide range of wild animal species throughout my life.
SARS and the Wuhan coronavirus both, according to expert opinion, had their origins in the crowded, filthy, and egregiously cruel depths of wild animal markets. It’s thought that SARS originated in masked palm civets (Paguma larvata), colloquially called the civet-cat, although they are not cats. This widely distributed Asian species of mammal is generally nocturnal and solitary, and thus can be assumed to be under horrific stress when jammed into small cages in filthy, crowded, noisy marketplaces. They spray strongly scented musk when threatened, not unlike skunks. Viruses thrive in stressed animals (and people) and are spread via bodily fluids.
It was first reported that snakes might be the origin of the Wuhan coronavirus, but that theory was dropped and, as I write, it is thought that the virus could have spread from bats. But, the real issue here is the wild animal markets themselves. As David Fisman, a professor of epidemiology and infectious disease physician at the University of Toronto’s Lana School of Public Health put it, “How many times must learn this lesson? Apparently quite a number of times.”
Health officials quite rightly are bending over backwards to assure us that we should not panic, and point to far, far more serious threats to our health and lives than these suddenly appearing zoonotic diseases have been to date. But, the concern, here, is not only human health and survival, but also animal welfare and conservation. The markets, like the factory farms and livestock transportation procedures found in North America, are just plain cruel. And, while the masked palm civet is not endangered, chimpanzees and many species of snakes, tortoises, and in fact dozens of other species of wildlife, are endangered as a result of the incessant, consumptive demands we place on their dwindling populations.
Keep Wildlife in the Wild,
