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.

Discussion

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.

Conclusions

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.

19 April 2021  Statement

 The seventh meeting of the Emergency Committee convened by the WHO Director-General under the International Health Regulations (2005) (IHR) regarding the coronavirus disease (COVID-19) took place on Thursday, 15 April 2021 from 12:00 to 16:30 Geneva time (CEST).

“One Health

Promote One Health approaches to better understand and reduce the risk of spill-over of emerging infections from animal to human populations and from humans to animals, including from domestic animals.

Work with partners to develop and disseminate joint risk-based guidance for regulation of wet markets and farms to reduce transmission of novel pathogens from humans to animals and vice-versa.

One Health

Strengthen regulation of wet markets and discourage the sale or import of wild animals that pose a high risk of transmission of novel pathogens from animals to humans or vice versa.

Conduct risk-based monitoring of animal populations to reduce disease transmission from animals to humans. Monitoring efforts should prioritize potential high-risk animal populations that may become reservoirs or lead to emergence of novel viruses or variants.”

One Health: Preventing and combating pandemics worldwide

April 19, 2021

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

Significance

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.

Abstract

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.

Global One Health initiative awarded CDC Cooperative Agreement to expand capacity and strengthen public health systems in Ethiopia

April 9, 2021

Apr 7, 2021

Source: CDC

The Ohio State University Global One Health initiative (GOHi) has been awarded $5.61 million in funding from the Centers for Disease Control and Prevention (CDC) to fight the COVID-19 pandemic and bolster Ethiopia’s public health system capacity for small- and large-scale disease outbreaks and emergencies.

Since 2009, GOHi has been on the front lines in Ethiopia working with in-country partners to strengthen capacity using a One Health approach—one that brings together multiple disciplines working globally to address the spread of disease, promote health and emphasize the connection among humans, animals, plants and the environment.

As new diseases emerge, the need for health system preparedness across the globe is vital for nations to prevent spread of pathogens, detect and report epidemics, and respond to and mitigate the spread of those epidemics. The current COVID-19 pandemic urgently underscored these needs. Under-preparedness in one country, is a global risk to all.
