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.

WCS Statement Upon the Inauguration of Biden-Harris Administration
"The United States needs to reengage in advancing environmental and conservation solutions as the world faces existential crises all caused by humankind: the loss of biodiversity, climate change, and the threat of pandemic disease," said WCS President and CEO Cristian Samper. "These crises are inter-related with many of the same causes and solutions."
WCS President and CEO Cristian Samper spoke during the One Planet Summit, hosted by French President Emmanuel Macron.
As part of this remarks, Samper said:
The world is facing three major crises today: the loss of biodiversity, climate change and the pandemic. They are all inter-related, with many of the same causes and solutions, and we need to recognize these synergies and find win-win solutions. We know that pandemics of zoonotic origin such as COVID-19 are directly tied to wildlife trade and the increase in the human-wildlife interface caused by deforestation and forest degradation. We also know that deforestation is one of the major causes of greenhouse gas emissions, and that more than a third of the solution to climate mitigation can come from nature-based solutions. Protected and conserved areas are at the heart of the solution.
Our treatment of nature increases the risk of further pandemics
As you increase the rate of deforestation in some areas and people move in there, WCS President and CEO Cristian Samper tells International Politics and Society, you’re increasing the human-wildlife interface. The likelihood that humans are coming into contact with different kinds of animals increases dramatically.
COMMENTARY: One Health and wildlife trade(-offs) – preventing future pandemics
An integrated One Health approach, which fully acknowledges the interconnectedness and interdependence of human, animal, plant, and environmental health, as outlined in the “Berlin Principles on One Health”, adopted in 2019, is paramount in tackling some of the most pressing global health challenges, including the potential for future pandemics.
COMMENTARY: Combating emerging disease threats in the Andean Amazon
The Amazon is the world's largest tropical forest. It's home to 1/4 of the planet’s terrestrial species. Therefore, it's a major source of concern for the emergence of zoonotic diseases, writes WCS's Yovana Murillo for PBS Nature.
Mongabay: Coronavirus risk grows as animals move through wildlife trade
A team of scientists, including from WCS, tested field rats for coronavirus at different points along the wildlife supply chain in Vietnam. They found that with each link in this chain, the percentage of infected animals increased by about 1.5 times.
WATCH: Wildlife conservation and zoonotic diseases
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.
COMMENTARY: A One-Health approach to this and future pandemics
"No particular country, group, discipline, or sector of society, write Niels Annen, Minister of State, German Federal Foreign Office, and WCS President and CEO Cristian Samper for Euractiv, "holds enough knowledge and resources to single-handedly prevent the emergence or spread of diseases while maintaining and improving the health and well-being of all species and ecosystems in today’s globalized world."
COMMENTARY: One Health is a necessary blend of biodiversity and human health goals
As we confront a pandemic originating with the zoonotic transmission of a virus from wildlife to humans that has devastated the global economy, writes WCS's Annie Mark for Mongabay, there is now an opportunity to combine these two areas.
“Banning the trade in live wildlife for human consumption is the first step to bring our planet back on the road to good health,” WCS's John Calvelli tells the Debi Nigro Show. “The proposed legislation is the prescription to do just that.”
WATCH: Strengthening the multilateral health architecture
The COVID-19 crisis is a reminder of the relationship between health and the environment. WCS's Sarah Olson spoke on zoonotic diseases, pandemics and the Berlin Principles at the launch of the "One Health" High-Level Expert Council.

TUNE IN: One Planet, One Health, One Future
COVID-19 has shown us the exorbitant cost of inaction. The world needs to urgently operationalize the concept of One Health. On November 17 and 18, WCS and the German Federal Foreign Officeare are co-hosting a two-day virtual event that builds on the Berlin Principles to identify how to move forward.
The world needs to urgently operationalize the concept of One Health
Global leaders in wildlife and human health are taking further active steps to ensure that governments, academia, and civil society break down barriers and form a united effort to prevent the emergence or resurgence of diseases, like COVID-19, that threaten people, wildlife, and livestock.
On November 17 and 18, WCS and the German Federal Foreign Office will jointly host a virtual meeting on how to operationalize One Health across the globe.
The pandemic could usher in fundamental improvements in how we treat animals and the planet, writes Rachel Nuwer for Sierra Magazine. SARS-CoV-2 has given us an opportunity to self-correct through actions like closing live-wildlife markets.
"Evidence is very strong," WCS's Joe Walston tells her, "that at our darkest hour, we're actually closest to a major inflection point that would put in place the foundations for a renaissance in nature."
Bat Week and emerging zoonotic disease threats are really about us, writes WCS's Sarah Olson. If we can shift attitudes and beliefs about bats, we can begin to have more difficult conversations about how we choose to live on this planet.
Piecemeal perspectives on preventing future zoonotic pandemics just won’t cut it
Our collective and determined actions can prevent outbreaks from becoming global pandemics, writes WCS Executive Director of Health Christian Walzer in Frontiers. But we, the global community, must strive to build back better.
The risk of coronavirus spillover increases as animals travel from traders to large markets to restaurants
In a recent study, WCS's Sarah Olson and her colleagues showed that 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. She explained in an interview with the Asia Society (about 32 minutes into the video below).

How WCS Canada scientists are adapting to COVID-19
Usually, at this time of year, many of WCS Canada's scientists would be deep into their field seasons, monitoring bird migrations in Yukon, tracking the movements of ancient sturgeon in Ontario, and joining with community partners to listen to whale sounds in the western Arctic. But current circumstances have required both adopting some creative solutions and simply accepting that some field work is not going to happen this summer.
COMMENTARY: How we can use the CITES wildlife trade agreement to help prevent pandemics
The best way, write WCS's Sue Lieberman and others, is to adapt CITES to address zoonotic disease risk is through an addendum to the treaty itself: additive text covering zoonotic diseases and international trade.
What’s the environmental impact of the COVID-19 crisis in Africa?
A paper in Nature Ecology and Evolution argues “that the net environmental impact of the COVID-19 crisis in Africa will be strongly negative because the crisis creates a ‘perfect storm’ of reduced funding, lower conservation capacity, and increased threats to wildlife and ecosystems. Wildlife conservation arguably faces its most serious challenge in decades.” WCS’s Uganda Country Director Simon Nampindo is among the authors.
Densely populated urban areas have garnered most of the media attention and public health response. What has been largely ignored, writes WCS's David Wilkie, is the impact of COVID-19 on Indigenous Peoples.
COMMENTARY: In Africa, wildlife raises the risk of deadly diseases. It doesn't have to.
We have seen the devastating impacts of diseases that spillover from wildlife, write WCS's Robert Mwinyihali, Jean Paul Kibambe, Richard Malonga and Gaspard Abitsi for CNN. "For urban families like ours, eating wildlife is not essential."
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.

The New York Times: Wildlife trade spreads coronaviruses as animals get to markets
A study of the wildlife trade in 3 provinces in southern Vietnam, co-authored by WCS, produced startlingly clear confirmation for one of the underlying objections to the wildlife trade in Asia—the trading offers an ideal opportunity for viruses in one animal to infect another.
Animals sampled in the wildlife-trade supply chain bound for human consumption had high proportions of coronaviruses and the proportion of positives significantly increased as animals traveled from traders to large markets to restaurants, says a new study co-authored by WCS.
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.
To reduce risk, we recommend stopping all commercial trade in wildlife for human consumption (particularly of birds and mammals) and closing all such markets.

EDITORIAL: The impact on small-scale fisheries and coastal communities
In a new piece for the journal Coastal Management, conservationists, including from WCS, document the effects the pandemic is having on this sector around the world.
"Negative consequences to date have included
complete shut-downs of some fisheries," they write, "knock-on economic effects
from market disruptions, increased health risks for fishers, processors
and communities, additional implications for marginalized groups,
exacerbated vulnerabilities to other social and environmental stressors, and increased Illegal, Unreported and Unregulated fishing."
COMMENTARY: CITES is not the answer to preventing another pandemic
WCS's Susan Lieberman argues the only way to truly prevent something is to eliminate the root cause. In the case of zoonotic pandemics, she writes for Scientific American, we must put an end to the commercial trade in wildlife for human consumption (with exceptions for Indigenous Peoples and local communities that are dependent on wildlife consumption for their food security or cultural expression).

“So far," said WCS Canada's Justina Ray, "there's really nothing that we can see at this point that would change the equation for the largest threat to species, which is cumulative habitat loss and degradation.”
For WCS's Jonathan Slaght spring was typically the end point of his yearly work studying Blakiston's fish owls, the world's largest owls, in Russia. "The thaw made river ice unsafe to walk or drive on," he writes in Scientific American, "and the sun’s renewed warmth softened the frozen mud of forest roads, making them impassable."
Not this year, though. This year, as COVID-19 tightened its grip on the planet, it became clear the expedition would leave him behind.

Fires in Mesoamerica
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.

According to Chris Walzer, Director of Global Health at the Wildlife Conservation Society, Amazonian creatures can be presumed to harbor just as many viruses as African and Asian animals that gave us Ebola, SARS, and COVID-19.
OPINION: China is closing its wildlife markets. Let’s make it permanent.
"The Chinese government is now leading the global community with these new regulations," WCS Regional Director Colin Poole writes for PBS Nature. "However, the real challenge lies in implementation—not today, but in years to come when a vaccine is widely available and the fear of Covid-19 is fading from memory."
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
Quarantining also means caring for our great ape relatives
Gorillas and other great apes are particularly susceptible to pathogens from humans, and the coronavirus responsible for COVID-19 poses a very serious risk to their survival. Protecting our closest wild relatives and closing wildlife markets for human consumption are both critical steps towards ensuring healthy futures for all, writes Elizabeth L. Bennett for IUCN.

Reminder of The Berlin Principles – A One Health approach — Issued on Oct. 22, 2019
As the world focuses on the zoonotic COVID-19 outbreak, we are bringing focus back to the Oct. 22, 2019, release of The Berlin Principles, which are an urgent call to governments, academia, and civil society that all sectors need to break down barriers to ensure a united effort to prevent the emergence or resurgence of diseases that threaten humans, wildlife, and livestock.
The Berlin Principles were developed and issued at the "One Planet, One Health, One Future" conference organized by the Wildlife Conservation Society and the German Federal Foreign Office. The conference included the top minds from around the globe addressing how human development and interference on nature are generating threats affecting all life on Earth.
“But there is a huge trade in wildlife that is not related to consumption.”

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.”
STATEMENT: WCS applauds China for revising and strengthening wildlife protection laws
“Preventing future zoonotic outbreaks is not about targeting one species—like pangolins, bats and snakes—but taking strong actions to ban wet markets trading in wildlife and broadly strengthening wildlife laws and regulations," said WCS's Dr. Christian Walzer. "We applaud The National People’s Congress of the People’s Republic of China for declaring on Monday that it is revising wildlife protection laws, in order to strengthen the fight to end indiscriminate hunting and consumption of wild animals."
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.
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
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.

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."
