Political issues raised to serve common good

August 14, 2020

“DEAR READERS: I have received a couple of letters from readers demanding that I keep to the subject of pet care in my Animal Doctor column. The evident reason is that they do not like my “politics.”

As an advocate of One Health (meaning the collective, connected health of humans, nonhumans and the environment), I raise issues concerning financially and ideologically driven political decisions that could harm the environment, animal health and public health. I regard this as my responsibility as a holistic veterinarian, just as it is the responsibility of all citizens to be involved in politics that serve the common good. I consider it ethically imperative to speak truth to power and examine the truths we live by, since a life unexamined is a life unlived. For further details and discussion, see my book “Animals and Nature First.”

Scientific evidence — essential for our decision-making when it comes to diagnosing, preventing and treating disease — should inform politics, rather than be discounted, as by some U.S. politicians in response to the COVID-19 pandemic. For more, see my article “What SARS-CoV-2 and COVID-19 Disease Are Telling Us: A Holistic Veterinary and One Health View,” posted on my website (”

Pharmaceutical Companies and Antimicrobial Stewardship: Save Us a Seat

August 12, 2020

“… AMR action plans are being implemented on global2 and national3 levels. In recognition of the interdependence of human, animal, and environmental health (the “One Health” perspective, Fig. 1), these plans encourage multisectoral collaboration, including (but not limited to) governments, agriculture, healthcare providers, and pharmaceutical industry. The pharmaceutical sector’s role in developing new antimicrobials is well recognized, but industry also helps to address AMR by supporting AMS. …”

Coronavirus testing indicates transmission risk increases along wildlife supply chains for human consumption in Viet Nam, 2013-2014

August 11, 2020


Large percentages of coronaviruses were detected in bats and rodents at sites where people have close contact and interact with wildlife including sub-interfaces along wildlife trade chains, wildlife farms, and artificial bat roosts where bat guano is collected for use as fertilizer. The high proportion of coronavirus positive samples at these human-wildlife interfaces highlights the potential for human exposure to wildlife origin coronaviruses. The observed viral amplification along the wildlife trade supply chain for human consumption, illustrated by the field rat trade in this study, likely resulted from the admixing of different species or sub-populations, and the close confinement of stressed live animals. This highlights the potential for coronavirus (and other virus) shedding and amplification along other wildlife supply chains (e.g., civets, pangolins) where similarly large numbers of animals are collected from a wide range of locations, transported, and confined. The detections of rodent, bat, and avian coronaviruses confirm concerns about productions systems and supply chains that increase contact between wildlife and domestic species. Livestock and people living in close contact with rodents, bats, and birds shedding coronaviruses provides opportunities for intra- and inter-species transmission and potential recombination of coronaviruses.

Human behavior is facilitating the spillover of viruses, such as coronavirus, from animals to people. The wildlife trade supply chain from the field to restaurant and end consumer provides multiple opportunities for such spillover events to occur [1]. Since the SARS outbreak, broad scientific consensus exists that long term, structural changes, and wildlife trade and market closures will be required to prevent future epidemics. To minimize the public health risks of viral disease emergence from the consumption of wildlife and to safeguard livestock-based production systems, we recommend precautionary measures that restrict the killing, commercial breeding, transport, buying, selling, storage, processing and consuming of wild animals. The time has come for the global community to collectively assume responsibility through targeted wildlife trade reform. The world must also increase vigilance through building and improving detection capacity; actively conducting surveillance to detect and characterize coronaviruses in humans, wildlife, and livestock; and to inform human behaviors in order to reduce zoonotic viral transmission to humans. The more opportunities we provide for humans to come into direct contact with a multitude of wildlife species, the higher the likelihood of another spillover event. The costs of inaction are astronomically high and we must ensure that future food production and security is sustainable, just, and supports global health.

Take zoonotic disease precautions

August 6, 2020

“DEAR READERS: A rise in zoonotic (animal-to-human) diseases is being driven by environmental degradation, according to a report by the United Nations Environment Program and the International Livestock Research Institute. The report cites rising demand for animal protein, intensive farming practices, exploitation of wildlife and climate change among key factors. The authors suggest adopting a One Health approach, which would unite public health, veterinary and environmental experts to respond to and prevent zoonotic disease outbreaks. (UN News, 7/6)

If preventive veterinary medicine had been applied in China and other countries to better monitor live animal markets and wild and domestic animal factory farms, in my professional opinion, this COVID-19 pandemic would have been much less likely to occur.

The COVID-19 pandemic has put in bold relief how the veterinary and medical professions, and associated public health services internationally, have failed to promote the first medicine: disease prevention. This responsibility has been corrupted by pecuniary interests and an increasingly distorted, dispirited and mechanistic perception of health, which is not simply the absence of disease. The human medical profession may be faulted for not engaging effectively in the politics of human overpopulation and ecologically damaging and unhealthful dietary choices. But many, along with veterinarians and other health care professionals and biological scientists, are rallying under the banner of One Health. This concept is not new, and enjoyed stronger endorsement and support in decades prior to the advent of clinical specialization in human and veterinary medicine. Steps to achieving the end point of this concept are well articulated by the One Health Initiative at”

The origin of COVID-19 and why it matters

August 4, 2020


Co-authors: David M. MorensJoel G. BremanCharles H. CalisherPeter C. DohertyBeatrice H. HahnGerald T. KeuschLaura D. KramerJames W. LeDucThomas P. Monath and Jeffery K. Taubenberger


The COVID-19 pandemic is among the deadliest infectious diseases to have emerged in recent history. As with all past pandemics, the specific mechanism of its emergence in humans remains unknown. Nevertheless, a large body of virologic, epidemiologic, veterinary, and ecologic data establishes that the new virus, SARS-CoV-2, evolved directly or indirectly from a β-coronavirus in the sarbecovirus (SARS-like virus) group that naturally infect bats and pangolins in Asia and Southeast Asia. Scientists have warned for decades that such sarbecoviruses are poised to emerge again and again, identified risk factors, and argued for enhanced pandemic prevention and control efforts. Unfortunately, few such preventive actions were taken resulting in the latest coronavirus emergence detected in late 2019 which quickly spread pandemically. The risk of similar coronavirus outbreaks in the future remains high. In addition to controlling the COVID-19 pandemic, we must undertake vigorous scientific, public health, and societal actions, including significantly increased funding for basic and applied research addressing disease emergence, to prevent this tragic history from repeating itself.

Strategies Needed to Ensure Higher Immunization Rates in the Americas

August 3, 2020

“In their MEDICC Review Perspective, Galindo-Santana and colleagues highlight the challenges presented by anti-vaccination groups, stressing that immunization is an essential cost-effective preventive measure that promotes population health.[1] In 2019, WHO identified vaccine hesitancy, fragile and vulnerable settings and weak primary health care as 3 of 10 main global health threats. Close attention to these threats can detect potential areas of missed opportunities for immunization across populations and mitigate risk of preventable diseases. …

… Third, primary health care centers can promote holistic health through the One Health concept, which describes the interconnectedness of human, animal, and environmental health, while dispelling myths and fostering provider–patient rapport and acceptance of evidence-based vaccination schedules.

Regional action for widespread adoption of evidence-based vaccination schedules is essential to safeguard population health. By prioritizing community-based research, health capacity building and the One Health concept, nations can accelerate progress to achieving high immunization coverage through Sustainable Development Goal targets 3.8 and 3.b.”

Five Environmental Lessons Coronavirus Could Teach Humanity, If Humanity Would Listen

July 26, 2020

“Now we must become more proactive to avoid another pandemic and address endemic zoonotic diseases,” said Inger Andersen, executive director of the United Nations Environment Program (UNEP). “This means recognizing that human health, animal health and planetary health cannot be separated, and planning our responses accordingly.”


But Anderson believes we also must stop thinking of human health separately from animal health and environmental health.

“Part of this process is the urgent adoption of integrated human, animal and environmental health expertise and policy – a One Health approach. One Health is not new, but uneven uptake and institutional support means it hasn’t hit its potential. The weakest link in the chain is environmental health. We have to fix this.”

So the coronavirus pandemic offers vital lessons for future threats.

“The U.S. has fared worse than other countries not because it lacked information or funding,” said Dr. Ali S. Khan, director of the Office of Public Health Preparedness and Response at the Centers for Disease Control and Prevention, “but because it failed to learn the lessons of the last outbreaks.”

Ecology and economics for pandemic prevention

July 24, 2020

“For a century, two new viruses per year have spilled from their natural hosts into humans (1). The MERS, SARS, and 2009 H1N1 epidemics, and the HIV and coronavirus disease 2019 (COVID-19) pandemics, testify to their damage. Zoonotic viruses infect people directly most often when they handle live primates, bats, and other wildlife (or their meat) or indirectly from farm animals such as chickens and pigs. The risks are higher than ever (23) as increasingly intimate associations between humans and wildlife disease reservoirs accelerate the potential for viruses to spread globally. Here, we assess the cost of monitoring and preventing disease spillover driven by the unprecedented loss and fragmentation of tropical forests and by the burgeoning wildlife trade. Currently, we invest relatively little toward preventing deforestation and regulating wildlife trade, despite well-researched plans that demonstrate a high return on their investment in limiting zoonoses and conferring many other benefits. As public funding in response to COVID-19 continues to rise, our analysis suggests that the associated costs of these preventive efforts would be substantially less than the economic and mortality costs of responding to these pathogens once they have emerged. …”

Farmed Animal Spillover

Livestock are critical reservoirs and links in emergent diseases. H5N1 influenza came across the human-wildlife interface (wild bird → poultry → human transmission chain), as did H1N1 influenza (bird → pig → human). Many livestock-linked outbreaks have reached the cusp of pandemic emergence, such as Nipah virus (fruit bat → pig → human) and swine acute diarrhea syndrome coronavirus (bat → pig) (14). These links are well recognized and are the focus of pandemic prevention packages proposed by the U.S. Congress (H.R. 3771). There are well-researched veterinary health plans such as the World Bank’s One World One Health farm biosecurity intervention program, designed to reduce H5N1 influenza risk. With costs in the tens of billions of dollars, proposals dealing with livestock’s roles in pandemics are among the most advanced and ambitious of those being seriously considered. We have known about these risks longer (e.g., influenza) and can control farm biosecurity more easily than wildlife contact in trade or at forest edges. … “

Again, Follow Dr. Fauci’s lead!

 “…we have long embraced a one-health paradigm at NIAID, especially in the realm of emerging and re-emerging diseases, most of which are zoonoses and must be studied in the context of the ecosystems humans share with microbes, non-human hosts, vectors, reservoirs and other actors.  Many of the research efforts about which I speak and write almost daily fall under the one health rubric, in that our studies are multi-disciplinary and have benefits not only for humans but for other species, agriculture, and other aspects of society and the environment.” [March 7, 2018 email to One Health Initiative (OHI) team, please see below*]

Fauci: ‘The Virus Is a Formidable Foe’

July 22, 2020

  • Young people are driving the latest surge of cases. They are making a big mistake by thinking it doesn’t matter if they get infected, even though many of them won’t get very sick. But allowing themselves to get infected means they are propagating the pandemic.
  • The anti-science trend mixes with an anti-authority trend, and scientists are often equated with authority. Young people may have been disappointed with government, which unfortunately adds to the anti-science sentiment.
  • A vaccine very likely will be available by the end of 2020, and the process of developing a vaccine is moving much more quickly than previously because of new technologies.
  • An NIH study is underway of 2000 families to look at the incidence of infection among children and the rate of transmission from children to adults, because it is not now clearly understood.
  • “This will end, and we will get back to normal.”
