One Health, Environmental Health, Global Health, and Inclusive Governance: What can we do?

April 30, 2021

About this Research Topic

The One Health concept refers to the key role of effective interaction between experience on the ground – the informed civil society – and political decision processes – an inclusive Governance – both supported by interactive science. Practice on the ground should help influence the governing level and the resulting changes towards more responsive and inclusive governance. On the other hand, governance should secure initiation and support of an active and well-informed practice widening its scope and coverage. This process includes multiple professional sectors, inter alia: mechanical engineering, pharmaceutical industry, economists, and agriculture, including forestry, education, veterinarians, physicians, political advocates, journalists, IT-technologists, and multiple other sectors development. The multiple professional sectors’ involvement must also include the often-neglected areas of legal aspects, sociology, and ethics. We need to go beyond bioethics and include environmental and biodiversity ethics, social science ethics, and rights aspects. To this end, legal experts, sociologists, and experts in ethics should be included in the implementation of One Health. This complex amalgam of expertise is predominantly oriented on three interrelated concepts: Global health, which underlines the steep gradients in human health between rich Western countries and, e.g., impoverished sub-Saharan countries in Africa; public health, which targets population health and the essential service infrastructure; and planetary health which targets the ecosystem as an interdependent and interactive system of air, water, land, plants, animals, and humans. One Health keeps these views on the destiny of humankind together.  . . .

“… “It will happen again…so we need to dramatically strengthen pandemic preparedness, and we need to do so together, across sectors, and as a global community,” said Henrietta Fore, executive director of UNICEF. “This means building political will towards a One Health approach, underpinned by policies and budgets that put preparedness first.”

The One Health concept views the health of humans, animals, and the environment as intrinsically linked. Speakers throughout the day made it clear that any national strategies to combat AMR must address how antibiotics are used in human and veterinary medicine and in agriculture.  …”

Striking the right balance … Recognizing that the health and well-being of humans, animals and the environment are intricately linked will help us shape a better tomorrow

April 27, 2021

“ …

Though the ‘One Health’ approach is considered crucial to address governance challenges of zoonotic diseases, its implementation in practice remains quite limited. It is time for international law to catch up with global reality. But global health scholars can neither simply focus on the health sector nor limit their work to scientific and technological improvement. All will have to realize that food, trade, human rights, humanitarian relief, and the environment are critically important in improving health and reducing health inequalities.”

   Mechanical transmission of SARS-CoV-2 by house flies

April 26, 2021

Abstract  Background

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a recently emerged coronavirus that is the causative agent of the coronavirus disease 2019 (COVID-19) pandemic. COVID-19 in humans is characterized by a wide range of symptoms that range from asymptomatic to mild or severe illness including death. SARS-CoV-2 is highly contagious and is transmitted via the oral–nasal route through droplets and aerosols, or through contact with contaminated fomites. House flies are known to transmit bacterial, parasitic and viral diseases to humans and animals as mechanical vectors. Previous studies have shown that house flies can mechanically transmit coronaviruses, such as turkey coronavirus; however, the house fly’s role in SARS-CoV-2 transmission has not yet been explored. The goal of this work was to investigate the potential of house flies to mechanically transmit SARS-CoV-2. For this purpose, it was determined whether house flies can acquire SARS-CoV-2, harbor live virus and mechanically transmit the virus to naive substrates and surfaces.


Overall, these studies demonstrated that house flies are indeed capable of acquiring, harboring and transmitting SARS-CoV-2. However, the low level of infectious virus carried by flies limits their capability for SARS-CoV-2 transmission.


In the present study, we determined that house flies could readily acquire and harbor SARS-CoV-2 from virus-spiked medium or virus-spiked milk. However, only viral RNA but no infectious virus was recovered from any environmental samples. These data suggest that flies most likely do not play a significant role in transmitting SARS-CoV-2 to humans and susceptible animals. However, the house fly’s ability to harbor SARS-CoV-2 viral RNA for extended periods might offer a potential for its use as a xenosurveillance vector for monitoring SARS-CoV-2 in communities, a technique which more traditionally has been used to survey blood-borne human pathogens by using hematophagous vectors [3132].

Anatomy Of A Spillover: We Failed To Stop SARS-CoV-2. How Do We Find Next ‘Big One’?

April 20, 2021

Heard on All Things Considered

Audio will be available later today.

“In movies such as Contagion, a pandemic begins in a flash. A deadly virus spills over from an animal, like a pig, into humans and then quickly triggers an outbreak.

But that’s not actually what happens, says Dr. Gregory Gray* at the Duke Global Health Institute. “It’s not like in the movies,” he says, “where this virus goes from a pig in Indonesia and causes a pandemic.”

… Now, writing in the journal Viruses, Gray and his colleagues propose an alternative approach to hunting down new viruses, which, they believe, will have a better chance of stopping the next pandemic.

The approach takes into account the latest information about how human pathogens emerge from wildlife and how pandemics begin.

Project description

Title: Global Project on Pandemic Prevention and Preparedness, One Health
Commissioned by: German Federal Ministry for Economic Cooperation and Development (BMZ)
Country: Global
Overall term: 2021 to 2024

“ … The pathogen causing this pandemic, SARS-CoV-2, has drawn attention to the importance of zoonotic diseases, in other words diseases that can be transferred from animals to humans. Many infectious diseases that are widespread among humans have their origin in the animal realm. Experts estimate that there are still around 1.7 million unknown viruses in wild mammals and birds. Of these, approximately 700,000 have the potential to cross over to humans.  …

 The term ‘One Health’ stands for an end-to-end, interdisciplinary approach. It strives to improve global health and reduce risks. To this end, One Health considers interdependencies and interactions between human, animal and environmental health. …

 … One Health is committed to preventive measures in all three areas. The German Federal Ministry for Economic Cooperation and Development (BMZ) strives to mainstream this approach in international (development) cooperation across different sectors. … ”

Ranking the risk of animal-to-human spillover for newly discovered viruses

April 12, 2021


The recent emergence and spread of zoonotic viruses, including Ebola virus and severe acute respiratory syndrome coronavirus 2, demonstrate that animal-sourced viruses are a very real threat to global public health. Virus discovery efforts have detected hundreds of new animal viruses with unknown zoonotic risk. We developed an open-source risk assessment to systematically evaluate novel wildlife-origin viruses in terms of their zoonotic spillover and spread potential. Our tool will help scientists and governments assess and communicate risk, informing national disease prioritization, prevention, and control actions. The resulting watchlist of potential pathogens will identify targets for new virus countermeasure initiatives, which can reduce the economic and health impacts of emerging diseases.


The death toll and economic loss resulting from the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic are stark reminders that we are vulnerable to zoonotic viral threats. Strategies are needed to identify and characterize animal viruses that pose the greatest risk of spillover and spread in humans and inform public health interventions. Using expert opinion and scientific evidence, we identified host, viral, and environmental risk factors contributing to zoonotic virus spillover and spread in humans. We then developed a risk ranking framework and interactive web tool, SpillOver, that estimates a risk score for wildlife-origin viruses, creating a comparative risk assessment of viruses with uncharacterized zoonotic spillover potential alongside those already known to be zoonotic. Using data from testing 509,721 samples from 74,635 animals as part of a virus discovery project and public records of virus detections around the world, we ranked the spillover potential of 887 wildlife viruses. Validating the risk assessment, the top 12 were known zoonotic viruses, including SARS-CoV-2. Several newly detected wildlife viruses ranked higher than known zoonotic viruses. Using a scientifically informed process, we capitalized on the recent wealth of virus discovery data to systematically identify and prioritize targets for investigation. The publicly accessible SpillOver platform can be used by policy makers and health scientists to inform research and public health interventions for prevention and rapid control of disease outbreaks. SpillOver is a living, interactive database that can be refined over time to continue to improve the quality and public availability of information on viral threats to human health.
