“… The UN Decade on Ecosystem Restoration is part of a series of collaborative efforts led by WHO that seek to strengthen cross-sectoral collaboration and engagement at the human, animal, plant and ecosystem interface, also known as One Health. …”

“… In fact, COVID-19 has galvanised our resolve to transform the paradigm of our development model. From destructive short-term thinking towards a sustainable model that respects the life of our planet and the lives of our citizens. [One World, One Health] “

ENTOMOLOGY TODAY

“…

Expanding testing efforts will not only gauge prevalence of these other pathogens in Pennsylvania but also benefit development of epidemiological models for predicting where human infection could occur. Through collaborative discussions and information sharing with the Pennsylvania Department of Health, we have commenced a “One Health” approach to tick-borne diseases, realizing that the intersection of our distinct work provides the greatest benefit. …”

“… Now One Health Needs Changed Behavior

Today One Health, the interface between human-animal-environmental health, is in much the same place as was nutrition in the last century. It is even more confounding because it touches virtually all of the United Nations Sustainable Development Goals. …”

Abstract Background:

The protozoan parasite Toxoplasma gondii has a worldwide distribution and a very wide host range, infecting most warm-blooded hosts. Approximately 30% of humanity is infected with T. gondii, but clinical toxoplasmosis is relatively infrequent. Toxoplasmosis has a wide range of clinical symptoms involving almost all organ systems. In most persons that acquire infection postnatally, symptoms (when present) are mild and mimic other diseases such as flu, Lyme disease, Q fever, hematological alterations, or mumps. It is likely that clinical disease is more common than reported. The ingestion of infected meat or food and water contaminated with oocysts are the two main modes of postnatal transmission of Toxoplasma gondii. The infective dose and the incubation period of T. gondii infection are unknown because there are no human volunteer experiments.

Methods: Here, I have critically reviewed outbreaks of clinical toxoplasmosis in humans for the past 55 years, 1966– 2020. Information from oocyst-acquired versus meat-acquired infections was assessed separately.

Results: Most outbreaks were from Brazil. There were no apparent differences in types or severity of symptoms in meat- versus oocyst-acquired infections. Fever, cervical lymphadenopathy, myalgia, and fatigue were the most important symptoms, and these symptoms were not age-dependent. The incubation period was 7–30 days. A genetic predisposition to cause eye disease is suspected in the parasites responsible for three outbreaks (in Brazil, Canada, and India). Only a few T. gondii tissue cysts might suffice to cause infection, as indicated by outbreaks affecting some (but not all) individuals sharing a meal of infected meat.

Conclusions: Whether the high frequency of outbreaks of toxoplasmosis in humans in Brazil is related to environmental contamination, poor hygiene, socioeconomic conditions, or to genotypes of T. gondii needs investigation.

Abstract

Test data generated by ~60 accredited member laboratories of the American Association of Veterinary Laboratory Diagnosticians (AAVLD) is of exceptional quality. These data are captured by 1 of 13 laboratory information management systems (LIMSs) developed specifically for veterinary diagnostic laboratories (VDLs). Beginning ~2000, the National Animal Health Laboratory Network (NAHLN) developed an electronic messaging system for LIMS to automatically send standardized data streams for 14 select agents to a national repository. This messaging enables the U.S. Department of Agriculture to track and respond to high-consequence animal disease outbreaks such as highly pathogenic avian influenza. Because of the lack of standardized data collection in the LIMSs used at VDLs, there is, to date, no means of summarizing VDL large data streams for multi-state and national animal health studies or for providing near-real-time tracking for hundreds of other important animal diseases in the United States that are detected routinely by VDLs. Further, VDLs are the only state and federal resources that can provide early detection and identification of endemic and emerging zoonotic diseases. Zoonotic diseases are estimated to be responsible for 2.5 billion cases of human illness and 2.7 million deaths worldwide every year. The economic and health impact of the SARS-CoV-2 pandemic is self-evident. We review here the history and progress of data management in VDLs and discuss ways of seizing unexplored opportunities to advance data leveraging to better serve animal health, public health, and One Health.

“… The report underlines the need for further trace-back at the wildlife farms that previously supplied the Huanan market and other Wuhan markets linked to positive cases, to include interviews and serological testing of farmers and their workers, vendors, delivery staff, cold-chain suppliers and other relevant people and their close contacts. The team concluded: “Surveys should be designed using a One Health approach in larger areas and more countries, including genomic surveys and structured serosurveys of high-risk potential reservoir hosts and their human contacts.”

“… Gregory Gray [MD, MPH] at Duke University, senior author on the Malaysian chimeric coronavirus study, also advocates for surveillance among pneumonia patients in areas known to be hot spots for novel viruses or places where large populations of animals and humans mix, such as live animal markets and large farms. “These spillovers take years,” Gray says. “It’s not like in the movies. They go through different steps to infect humans.” So far indications are that the chimeric virus has not evolved to transmit efficiently between people.”

“… Because of these virus spillovers, Gray, Toh, and Vlasova continue to advocate for a focus on human-animal nexus surveillance. As Gray and co-author Anfal Abdelgadir, BDS, MSc, write in a 2021 Open Forum Infectious Diseases commentary, more human-animal interaction inevitably creates opportunities for novel strains, but it can take years of evolution and ineffective spillovers for these pathogens to become infectious and transmissible among humans.

“The most strategic approach would be directing periodic, novel respiratory virus surveillance at the human-animal interface, studying both animal workers and their animals,” they write, advocating for a One Health approach, which looks at the holistic and interconnected relationships between all organisms’ health and is being highlighted today by the World Health Organization. …”

SHANGHAI (Reuters) – The World Health Organization and three other international bodies have formed a team of experts to help develop a global plan to prevent the spread of diseases from animals to humans, the WHO said on Thursday.

The One Health High-Level Expert Panel was an initiative launched by France and Germany late last year, and held its inaugural meeting this week.

It will advise the WHO, the Food and Agriculture Organization, the World Organization for Animal Health and the United Nations Environment Programme on developing “risk assessment and surveillance frameworks” and establish “good practices to prevent and prepare for zoonotic outbreaks.”  …

The programmes are meant to raise healthcare providers’ awareness about the importance of curbing the overuse of antibiotics

“… The initiative comes in conjunction with the “One Health” approach announced by the WHO to design and implement programmes, policies, legislation, and research to achieve the best results in the field of public health. Combating antibiotic resistance is among the areas covered by this approach. …”
