WCS COVID-19 Policy (June 2021)

WCS recommends stopping the trade and sale of live or freshly killed wild birds and mammals for human consumption, in particular to urban venues, whether supplied from wildlife farms or wild-caught.

Act Now

Ecological Integrity and Human Health

Ecological degradation increases the overall risk of zoonotic disease outbreaks originating from wildlife, illustrates this WCS report.

Act Now

Urban Bushmeat and Infectious Disease

We can reduce the risk of outbreaks by changing social norms on urban bushmeat consumption and stopping its commercial trade, says this WCS report.

Act Now

Considerations for Official Development Assistance

ODA can contribute to reducing the risk of future emerging zoonotic diseases from wildlife.

Act Now

COVID-19 and Indigenous Peoples

Both during this COVID-19 pandemic, and to help prepare for a future outbreak, seven ways forward to support these communities.

Act Now

One Health in Action

WCS leverages its unique veterinary, health and conservation capacity to deliver on five core One Health approaches.

Act Now

Pandemic Prevention at Source

Pandemic prevention at source is the single most effective—and cost-effective—way to prevent pathogen spillover.

Act Now

WCS Health Program

WCS developed its Field Veterinary Program—the first and largest of its kind—in 1989 in response to the growing recognition of the critical role of wildlife health in both conservation and development. The program later expanded to become the innovative WCS Health Program, working around the world on a range of threats facing wildlife, livelihoods, and human health. The program is led by Executive Director Dr. Christian Walzer.

Protect Wildlife. Protect Us.

The commercial wildlife trade for human consumption is leaving us exposed to the threat of deadly, zoonotic pandemics. Together, we can project a better future. Learn more about our efforts and take action with us.

The leaders at the G-7 Summit made several important commitments addressing the interlinked existential crises facing our planet—climate change, biodiversity loss, and zoonotic pandemics. The renewed focus on nature by these nations is an essential step for the world to successfully tackle these crises.

On health, though, one element is missing from the members' commitment. Although we appreciate the attention on preparedness and post-spillover responses, they missed the chance to make a commitment to take the critical actions needed to prevent the next spillover of zoonotic pathogens from wildlife and other animals to people.

PREVENTING PANDEMICS AT THE SOURCE: Statement in advance of the 74th World Health Assembly

Post-spillover preparedness and response efforts alone, as emphasized by the World Health Organization and its advisors in the World Health Assembly agenda, draft resolutions, and other important inputs, will not prevent future pandemics.

“To prevent the next pandemic, efforts at better preparedness and public health are laudable, but will not be enough. An ounce of prevention is truly worth a pound of cure. Governments, and all of us, must work across disciplines and take all necessary actions, including protecting and retaining intact ecosystems, and closing down commercial wildlife markets for human consumption, particularly in birds and mammals, and the trade that supplies those markets.”
—WCS's Susan Lieberman

“The world faces four tightly interlinked existential crises—biodiversity loss, climate change, global inequities, and the constant and growing threat of zoonotic-origin pandemics, all a result of human actions, linked to an ongoing breakdown in our relationship with nature. We need to respond to these crises across sectors and with a sense of urgency.”

WCS's Sofi Mardiah, Wildlife Trade Policy Program Manager for Indonesia, presented at the ASEAN webinar, "Wildlife conservation and zoonotic diseases | Halting species loss and tackling public health in the Asean."

Among her priority actions and recommendations:

Strengthening policy and institutional framework
ASEAN nations need to ensure their policy frameworks and legislation prohibit the highest risk parts of the wildlife trade where zoonotic pathogens can emerge. Our research has shown that is the commercial trade in wildlife (particularly birds and mammals) for human consumption.

Strengthen pandemic prevention through a multi-sectoral “One Health” approach
Create a high-level multi-sectoral authority at the highest level of government, to oversee wildlife-livestock-human-environment issues of risk for zoonotic diseases; develop a national strategy as an umbrella to bridge the multi-sectoral work and translate it into priority areas and sub-national policy level.

Reduce consumer demand through BCC approach
Identify zoonotic disease risk in wildlife markets and trade; raise public awareness of disease risks; implement behavior change interventions targeting key wildlife consumers.

Has Vietnam banned the wildlife trade to curb the risk of future pandemics?

On July 23, the Vietnamese Government released Prime Minister’s Directive No. 29 on urgent solutions to manage wildlife. This has been largely reported in the global media as a widespread ban on wildlife trade in response to the COVID-19 pandemic. The Wildlife Conservation Society welcomes the Prime Minister’s Directive and the renewed attention it will bring to combating illegal trade and consumption of wildlife. However, there are a number of points that have been mis-reported in the global media and areas we think require greater attention to reduce the risks of future zoonotic pathogen outbreaks:

1) The Directive does not ‘ban the wildlife trade’; rather it calls for heightened enforcement of existing laws on illegal wildlife trade in Vietnam.

Directive No. 29 does not introduce new restrictions on the trade and consumption of wild animals to reduce the risk of zoonotic pathogen transmission, as we have seen in China. Instead, it simply re-states the need to enforce existing legislation on wildlife protection. However, the Directive requests the courts and prosecutors to impose strict penalties on those who abuse their position and authority to commit wildlife crimes. This is the first time such corruption has been acknowledged and prioritized.

This Prime Minister and earlier ones have previously issued Directives calling for enhanced enforcement efforts on illegal wildlife trade (See Prime Minister’s Directive No. 3/CT-TTG 2014; and Prime Minister’s Directive No. 28/CT-TTG 2016). Whilst these often result in a flurry of action, this invariably fades. All these Directives have been unable to address the underlying causes of weak enforcement and ineffective prosecutions against wildlife criminals – for which additional legal reform is urgently needed. The major obstacles include corruption within the criminal justice system, and insufficient resources applied to fighting wildlife crimes in terms of budgets, manpower and technical capacity (e.g. financial investigations).

2) The Directive paves the way for future legal reform on wildlife consumption.

Directive No. 29 has not banned the consumption of wildlife; rather it has requested all relevant ministries to strictly monitor and control the acts of illegal wildlife consumption and review the current legal framework to propose amendments and supplementary regulations on the illegal consumption of wildlife. This is a positive development but requires specific time-frame, guidance, and specific government agencies to lead the process, without such it could take more than a year to finalise.

3) Measures proposed in the Directive to reduce the risk of zoonotic pathogen transmission in commercial wildlife farms are insufficient.

Directive No. 29 calls for an inspection of commercial wildlife farming across the country to ensure the legal origin of captive wildlife and safe conditions for human and captive wildlife, environmental sanitation and disease prevention. This is urgently needed as commercial wildlife farms are a high-risk interface for the transmission of zoonotic pathogens, as evidenced by viral surveillance in Vietnam over the last decade that has found multiple known and novel viruses in such farms. However, the inspection must be prioritized, time-bound, involve the relevant line agencies of the Ministry of Health, Ministry of Natural Resources and Environment and also representatives from international organizations such as FAO and WHO.

Given the significant risks that commercial wildlife farms currently pose, and the challenges of implementing effective disease prevention and and biosecurity practices, we believe an immediate temporary ban on issuing new permits for captive-raising of wild mammals and birds for commercial purposes should be put in place during the period that inspection, risk assessment and updated policies are formulated and implemented.

4) The Directive potentially weakens the existing ban on wildlife imports.

The Prime Minister issued a temporary ban on all wild animal imports on January 28th 2020 in Directive No. 5 on Prevention and Combating COVID-19. The Ministry of Agriculture and Rural Development (MARD) issued official guidance on February 6th 2020 stipulating that parts of wild animals processed into medicines, perfumes, watches and bags would be exempt from this ban. Directive No. 29 repeats the existing ban, however, adding additional exemptions. MARD should clarify as soon as possible the precise scope of these additional exemptions.


Whilst this Directive No. 29 is a positive development, it is not the game-changer that is being reported by some in the global media and that is urgently needed to prevent future zoonotic pathogen outbreaks such as that we are experiencing today. WCS will continue our work with partners in the Vietnamese Government, local academia and civil society, in addition to FAO and WHO representatives in Vietnam, on proposals to reform legislation to prohibit the commercial trade and consumption of wild birds and mammals, and ensure that enforcement and judicial agencies are fully mandated and resourced to enforce the law and bring wildlife criminals to justice.

Wildlife in the trade supply chain are often under stress and confined at high densities with other animals from multiple sources which likely results in increased shedding of coronaviruses. The authors forewarn of the potential risk of viral spillover into people through the wildlife trade.

Fires in Mesoamerica

Photo Credit: ©Edwin Godoy

This young Guatemalan black howler monkey has lost its home. With forest rangers sheltering due to the COVID-19 crisis, fires raged uncontrolled across Mesoamerica on Earth Day last week, including in northern Guatemala’s Maya Biosphere Reserve, which WCS has worked to conserve for more than two decades. This infant monkey was discovered there in the ashes, in the community forests of San Miguel la Palotada.

The young monkey’s mother could not be found, so the baby was sent by CONAP (Guatemala National Council of Protected Areas) to the ARCAS Wildlife Rescue Center in Peten, and will require care and some growth prior to being returned to the wild.

The fires in Mesoamerica bring into focus the intersecting crises of the pandemic, climate change, and biodiversity loss. The blazes, exacerbated by drought, have released massive amounts of carbon into the atmosphere—contributing further to the climate crisis while threatening innumerable wildlife species like the young howler. What we increasingly know: the degradation of nature across the globe is driving catastrophic threats to our very survival.

WCS Fact Sheet: Big cats, SARS-COV-2 and COVID-19

COVID-19 is a disease caused by the coronavirus SARS-CoV-2. Although COVID-positive people can infect tigers and lions in zoos by close contact involved with caring for them, cats are not easily infected, and SARS-CoV-2 is not known to occur in any population of any wild cat species in nature. It is extremely unlikely that wild cats can transmit the virus that causes COVID-19 to humans

The New York Times: China ban big but traffickers may exploit loopholes, conservationists say

Dr. Christian Walzer, WCS’s chief global veterinarian, said China's new ban “is a big step in the right direction.” The ban goes to the “root cause” of the COVID-19 outbreak, he said which he and most other scientists view as human harvesting of wild animals.

“But there is a huge trade in wildlife that is not related to consumption.”

February 26, 2020

STATEMENT: A critical and positive step but other forms of trade should be added

“WCS welcomes this critical and positive step that reflects the Chinese central government’s commitment for not only solving the COVID-19 outbreak but in preventing future risks through legislative reform and improved enforcement and management.

“There is no such risk-free trade and consumption of any wild mammals and birds whether they are wild-caught or farmed. WCS believes that only by prohibiting the live trade in all wild birds and mammals can the risk of future viral emergences be prevented, and thus other forms of trade should also be included in this ban.

“In addition, this creates a potential loophole for traffickers who may exploit the non-food exemptions to sell or trade live wildlife, creating additional challenges to law enforcement officers.”

VIDEO: Wildlife markets are the most important factor in the emergence of COVID-19

January 30, 2020

Key questions answered

What is the Wildlife Conservation Society's main message concerning the COVID-19 coronavirus?

As Dr. Walzer states in the video above, WCS is asking China and others governments to close live animal markets that trade in wild animals—whether these animals come from the wild or whether they are farmed-wildlife. There are three clear steps we are advocating for to prevent the spread of similar zoonotic diseases: close live animal markets that sell wildlife; strengthen efforts to combat trafficking of wild animals within countries and across borders; and work to change dangerous wildlife consumption behaviors, especially in cities.

Won’t closing these markets hurt the poor?

No. Wildlife populations are being depleted as they are poached and hunted. Viral outbreaks lead to mass culling of domestic animals, which increases the cost of basic animal protein, hitting the poor the hardest.

Why do we suspect the COVID-19 coronavirus is a spill-over from animals to humans?

Scientists from the Chinese Centre for Disease Control have confirmed a live animal market teeming with a multitude of wildlife species as the origin of the COVID-19 coronavirus. Dr. Zhong Nanshan, director of the China State Key Laboratory of Respiratory Disease, who became famous for leading the fight against SARS 17 years ago, pinpointed on Chinese state television the likely source of the new coronavirus as wildlife. Environmental samples from the Wuhan market have been linked to wildlife.

Why are these live animal markets that sell animals for food such a problem?

It is hard to design more perfect conditions for new viruses to emerge than market systems such as that in Wuhan: Tightly pack together a variety of species from around the country or the world and transport them long distances directly into large markets. Ensure that these massively stressed and immuno-compromised wild animals are in close proximity to domestic and farmed animals. Then distribute these animals out to major urban populations for consumption.

What action has the Chinese government taken about these markets with this outbreak?

The Chinese government is to be applauded for acting quickly, as three government agencies took the first step, announcing a nationwide ban prohibiting all wild animal trading activities with immediate effect. This includes not only wet markets, but supermarkets restaurants and e-commerce platforms. The announcement also stated that “any violation of the provisions of this announcement shall be investigated and dealt with severely in accordance with the law and regulations”. However, this is not enough, as the ban currently only covers the period until “the epidemic situation is lifted nationwide”. It must be permanent.

Is it a common occurrence for viruses to be transmitted from animals to humans?

The resulting re-assortment and exchange of viral components between species at live animal markets is a major source of new viruses. These can be zoonotic, i.e., transmitted from animals to humans (e.g., Avian Influenza, SARS, MERS), and subsequently successfully mutate so that they can transmit between humans, creating the conditions for a rapid global pandemic.

Are there markets like this outside of China?

Similar markets occur in cities across other Asian countries and if these persist, and human consumption of wildlife goes on, then we will continue to face heightened risks from emerging new viruses, potentially more lethal.

Photo Credit: ©WCS Vietnam

What do the people in China and Chinese media think about closing these markets?

A large and growing number of people in China support closing these markets. On Chinese social media, support for the issue has been among the highest trending topics on Weibo (China’s most popular microblog site) over the last week, with the hashtag “#The Source of the New Coronavirus is Wild Animals” viewed 1.2 billion times. The hashtag "#National Wildlife Trading Is Banned Until the Epidemic is Over” has amassed 400 million views over 24 hours since it was announced, and the view of Chinese netizens is clear: “It should be permanently banned. Do you want to have another epidemic?,” “Reject wild meat, ban forever and punish offenders severely,” “It is for the sake of human life, health, safety, and maintenance of natural harmony that wildlife trading activities should be permanently banned from now on.”

Not only that. State media and academics agree. The China Daily recently headlined, “It’s Time to Permanently Ban Wildlife Trade” and Sina News, “It’s Time to Ban Wild Animal Trading.” While a group of senior Chinese academics, including the former president of Peking University and Dr. Shi Zhengli of Wuhan Institute of Virology, Chinese Academic of Science (who is one of the scientists who identified bats as the original carrier of SARs), have publicly called on China’s National People’s Congress to end the illegal trade and consumption of wild animals by issuing emergency legislation integrating public health and safety concerns into the wildlife protection law.

STATEMENT: Chinese ban on wildlife markets needs to be permanent

“The Chinese government’s announcement today to temporarily ban the sale of wildlife in markets, restaurants and over e-commerce needs to be permanent," said WCS's Dr. Christian Walzer. "We congratulate the government for taking this important first step."

“The banning of such sales will help end the possibility of future outbreaks of zoonotic diseases, such as the COVID-19 coronavirus. We learned this lesson with the outbreak of another zoonotic disease, SARS, in 2002. The pattern will keep repeating itself until we ban, not only in China, but in other countries, the sale of wildlife, specifically for food and in food markets."

The Guardian: Calls for global ban on wild animal markets

Photo Credit: ©WCS Vietnam

Wild animal markets must be banned worldwide, say experts in and outside China, warning that the sale of sometimes endangered species for human consumption is the cause both of the new coronavirus outbreak and other past epidemics.

The Huanan seafood market in Wuhan, which has been closed down as the source of the infection, had a wild animal section, where live and slaughtered species were on sale. An inventory list at the Da Zhong domestic and wild animals shop inside the market includes live wolf pups, golden cicadas, scorpions, bamboo rats, squirrels, foxes, civets, hedgehogs (probably porcupines), salamanders, turtles and crocodiles. In addition, it offered assorted parts of some animals, such as crocodile tail, belly, tongue and intestines.

January 22, 2020

STATEMENT: Close live animal markets that trade in wildlife

“Governments must recognize the global public health threats of zoonotic diseases," said WCS's Dr. Christian Walzer. "It is time to close live animal markets that trade in wildlife, strengthen efforts to combat trafficking of wild animals, and work to change dangerous wildlife consumption behaviors, especially in cities. It is essential to invest resources not only into discovering new viruses but more importantly in determining the epidemiological drivers of zoonotic spillover, amplification, and spread of infectious diseases."
