Wildlife trade and zoonoses

The possibilities for zoonotic disease transmissions

Wildlife trafficking practices have resulted in the emergence of zoonotic diseases. Exotic wildlife trafficking is a multi-billion dollar industry that involves the removal and shipment of mammals, reptiles, amphibians, invertebrates, and fish all over the world.[1] Traded wild animals are used for bushmeat consumption, unconventional exotic pets, animal skin clothing accessories, home trophy decorations, privately owned zoos, and for traditional medicine practices. Dating back centuries, people from Africa,[2][3] Asia,[4][5][6][7] Latin America,[8][9] the Middle East,[10] and Europe[11] have used animal bones, horns, or organs for their believed healing effects on the human body. Wild tigers, rhinos, elephants, pangolins, and certain reptile species are acquired through legal and illegal trade operations in order to continue these historic cultural healing practices. Within the last decade nearly 975 different wild animal taxa groups have been legally and illegally exported out of Africa and imported into areas like China, Japan, Indonesia, the United States, Russia, Europe, and South America.[12]

Consuming or owning exotic animals can propose unexpected and dangerous health risks. A number of animals, wild or domesticated, carry infectious diseases and approximately 75% of wildlife diseases are vector-borne viral zoonotic diseases.[13] Zoonotic diseases are complex infections residing in animals and can be transmitted to humans. The emergence of zoonotic diseases usually occurs in three stages. Initially the disease is spread through a series of spillover events between domesticated and wildlife populations living in close quarters. Diseases then spread through series of direct contact methods, indirect contact methods, contaminated foods, or vector-borne transmissions. After one of these transmission methods occurs, the disease then rises exponentially in human populations living in close proximities.[14]

After the appearance of the COVID-19 pandemic, whose origins have been linked to the Huanan Seafood Wholesale Market in Wuhan, China, Elizabeth Maruma Mrema, the acting executive secretary of the UN Convention on Biological Diversity, called for a global ban on wildlife markets to prevent future pandemics.[15] Others have also called for a total ban on the global wildlife trade[16] or for already existing bans to be enforced, in order both to reduce cruelty to animals as well as to reduce health risks to humans,[17][18] or to implement other disease control intervention measures in lieu of total bans.[19][20][21]

Wildlife trade, both legal and illegal and in all jurisdictions, must be abolished. All this must be done with due respect for differently resourced low- and middle-income countries and for the needs of those indigenes who through physical need and customary tradition engage in (non-commodified) subsistence hunting.

The horrific coronavirus disease 2019 (Covid-19) pandemic that we are experiencing, of which we still do not fully understand the likely economic, political, and social global impacts, is linked to wildlife trade. It is imperative that wildlife trade for human consumption is considered a gigantic threat to both human health and wildlife conservation. Therefore, it has to be completely banned, and the ban strictly enforced, especially in China, Vietnam, Indonesia, and other countries in Asia
