作者简介:
陈昊,中国人民大学医学史方向副教授。最新著作有《身份叙事与知识表述之间的医者之意:6-8世纪中国的书籍秩序、为医之体与医学身份的浮现》和《疾之成殇,秦宋之间的疾病名义与历史叙事中的存在》。
内容提要
《人类流行病中的非人类动物:过去和现在》一文,从历史和现实角度分析了人类流行病中非人类动物扮演的角色和被污名化的困境。
陈昊指出,无论在历史还是现实中,对于病毒起源的探索很快就演变为一场针对病毒的物种源头和谁该为病毒的跨物种传播负责的猎巫行动,进而在一场广泛的野生动物恐慌中,引发残忍而灾难性的动物管理方法。在灭杀“恶棍”动物,拯救“无辜”人类的同时,也引发进一步的生态灾难。
对于防止流行病引发的生态破坏行为,陈昊认为科学家与历史学家等应当合作。新冠肺炎揭示了缠绕于人类与非人类、身体和景观、地方和全球生态之间流动的、非线性的相互作用关系,能够让我们以一种不同的方式度过这场大流行,在这种方式中,非人类动物和生态系统可以与我们一起恢复。
During this devastating period of COVID-19, the media worldwide has
celebrated optimistic, even utopian, stories about domestic or wild
animals reclaiming the streets, parks, and even canals while humans
stayed home in lockdown mode. The good feelings prompted by these
uplifting stories have occasionally been shattered, however, by
disturbing news. In March, for instance, local veterinary officers from
India began to report abnormal behavior and deaths among monkeys. On
April 8, 2020, several media reported the deaths of at least fifteen
simians in Pawansa village. Believed to have died from pneumonia, a
common complication of COVID-19, the simians’ deaths contributed to
rising concern about cases of infected animals, from companion dogs in
Hong Kong and stray cats in Wuhan to three lions and four tigers at New
York’s Bronx Zoo (including Nadia, a Malayan tiger that serves as one of
the zoo’s main attractions). The list did not stop there. On April 26,
the Agriculture Ministry of Holland confirmed that animals from two mink
farms were infected with the novel coronavirus.
How had those animals become infected? What are their fatality rates?
And do the rates pose a threat to the species? Will infected animals
transmit the disease to other animals or species nearby? We have limited
scientific knowledge with which to answer these questions. One of the
few research articles on animals with COVID-19 appeared in Science in
early April and claimed that ferrets and cats are more susceptible to
infection than are dogs, pigs, chickens, and ducks and that cats are at
risk of airborne infection.However, this does not mean that dogs could
not get infected and die from COVID-19. In an article that appeared in
Nature, the Agriculture, Fisheries, and Conservation Department of Hong
Kong acknowledged that pet owners could inadvertently infect their
companion dogs with the virus. Unfortunately, one such dog, a
Pomeranian, the first known human-to-animal case, died on March 16
without any related symptoms. Like the simians in Pawansa village, we do
not know for sure whether the virus caused its death.
Neither article sought to resolve the mystery of the death of the
animals but, rather, to suggest advisable strategies for “animal
management” during the pandemic. The case in Hong Kong, for instance,
highlights the necessity of quarantining companion mammals when the
owner tests positive. The foundation of the management strategies rests
on an anthropocentric concern for how the virus might “jump” from
animals to humans. This worry became a reality on May 20 when the Dutch
minister of agriculture, Carola Schouten, confirmed that a mink farm
worker might have gotten infected from the sick minks. Two similar cases
were reported shortly thereafter, marking what may be the first reports
of animal-to-human transmission with solid scientific evidence.
Investigation into this zoonotic disease had begun earlier, when the genetic code of the RNA virus was sequenced at the onset of the COVID-19 outbreak. The search for the origins of the novel coronavirus quickly turned into a witch hunt, however, with two related questions: from which species did the virus “originate” and who should be held responsible for the species barrier jump? Epidemiologists and virologists suggested possible nonhuman animal hosts prior to human infection: bats, pangolins, and ferrets were among the more prominently mentioned possibilities. When these discussions entered the horizon of mass media and the public, unfortunately, much fear and panic toward wild animals also appeared. This kind of anxiety was not without precedent, stretching back at least to the 1990s with the greater awareness of “emerging infectious diseases” originating in wild animals and constituting a serious threat to public health. The danger lies in how a fear-driven overreaction can lead to a brutal and disastrous method of “animal management” during pandemics. In the past, our attempts to use chemicals to kill insects as disease vectors led to species extinction and ecological catastrophe. Poultry species have been euthanized and rendered innocuous all over the world to prevent potential flu viruses from jumping the species barrier. Sadly, death will become the inevitable fate of too many infected nonhuman animals in the pandemic, killed either by the virus or by humans seeking their own protection. Moreover, their deaths may precipitate further ecological disasters.
How can we act differently to prevent this pandemic from triggering actions that create ecological damage? To do so, we will need to rely on scientific research. Importantly, scientists and the policy-makers who sponsor the research can gain a critical and reflective perspective from the study of past epidemics and pandemics. To provide that, historians will need to carefully explore the long history of past pandemics. Recently, historians and anthropologists have sought to dig up the historical and epistemological roots of our ways of understanding and treating nonhuman animals in past epidemics. It seems that we have followed a script composed by the microbiological revolution: pathogens as villains, nonhuman animals as evil sidekicks who carry the pathogens, and humans as innocent victims forced to fight back.
Contemporary
research into “emerging infectious diseases” has enhanced our
understanding of the connection between pathogens and nonhuman animals,
however. According to medical anthropologist Christos Lynteris, “the
resurgence of zoonotic and vector-borne diseases in the course of the
twenty-first century (SARS, Bird Flu, MERS, Ebola, Zika and Nipah) has
fostered and complicated scientific framings of nonhuman animal and
insect hosts and vectors of infectious diseases as ‘epidemic
villains.’”It has switched the character of pathogens and their animal
hosts: now, nonhuman animals appear as the cunning villains who use
pathogens as a weapon. But efforts to find alternative ways to
understand the connections among pathogens, nonhuman animals, and humans
in epidemics need not attempt to pin blame on any particular species.
With various conceptual tools to erase the illusion of a divide between
humans and nonhumans, the infected nonhuman animals should be a
significant part of the histories that we will write about the COVID-19
pandemic. Indeed, COVID-19 can be used to demonstrate the fluid,
non-linear, and interactive associations intertwining human and nonhuman
animals, body and landscape, local and global ecology in the process of
the pandemic. Hopefully, recognizing the associations will enable us to
go through this pandemic in a different way, wherein nonhuman animals
and the ecological system can recover along with us.
