Mongabay Environmental News · Declining biodiversity and emerging diseases are entwined, more study neededFive years ago, the COVID-19 pandemic served as a wake-up call. Since then, health experts worldwide have sat on tenterhooks, hyperaware that pathogens can jump from animals to humans at any moment, bringing the next disruptive global health crisis that kills millions. But COVID-19 didn’t happen in a vacuum. Researchers have long warned that human […]

Why #biodiversity loss fosters #zoonotic disease. This article from 2010 is an eye opener.

NatureImpacts of biodiversity on the emergence and transmission of infectious diseases - NatureChanges in biodiversity have the potential to either increase or reduce the incidence of infectious disease in plants and animals — including humans — because they involve interactions among species. At a minimum, this requires a host and a pathogen; often many more species are involved, including additional hosts, vectors and other organisms with which these species interact. Felicia Keesing and colleagues review the evidence that reduced biodiversity affects the transmission of infectious diseases of humans, other animals and plants. Despite important questions still to be answered, they conclude that the evidence that biodiversity exerts a protective effect on infectious diseases is sufficiently strong to include biodiversity protection as a strategy to improve health.

The #CDC did something AWESOME! Along with the USDA & Dept of Interior, it released the first-ever

“National One Health Framework to Address #Zoonotic Diseases & Advance Public Health Preparedness in the United States”

- for #health threats people & animals SHARE, including #covid19, #mpox #AvianFlu, and #Ebola

'​​Zoonotic diseases on the rise in the EU: listeriosis cases hit highest levels since 2007​'

#eu #foodsafety #zoonotic

European Food Safety Authority​​Zoonotic diseases on the rise in the EU: listeriosis cases hit highest levels since 2007​The number of reported human cases of listeriosis (2,952) showed a consistent rise over the 2019–2023 period, hitting their highest levels since 2007. This might be linked to Europe's ageing population — 21.3% of Europeans are now over 65 years old — which, in connection with the growing prevalence of chronic age-related diseases, raises the risk of severe symptoms in older age groups. Contaminated ready-to-eat (RTE) foods, such as cold smoked salmon, meat products and dairy products, are the most common source of infections. The latest data show that the proportion of samples from RTE food...

Question about #zoonotic transmission of #covid specifically with #Dogs

The person who usually helps me with my dog went and got covid (basically on purpose, I'm so angry, but anyway) - if he tests negative on rapid test but hasn't had a PCR recently, do you think it's safe, for my dog and for myself, if he watches my dog at his home for a few hours?

The CDC updated their guidelines this spring, but they're so laissez-faire with humans I don't completely trust them.

#Oropouche fever, a potentially fatal #zoonotic disease, is transmitted by tiny flies called #midges and #mosquitoes.. There is currently no vaccine for the virus, which is part of the same family of diseases as #Zika and #dengue fever.”

What is the #relationship between #viral #prospecting in #animals and medical #countermeasure development? MedRxIV: medrxiv.org/content/10.1101/20

With #Filoviridae as a case study, we show there is little #evidence to suggest that viral prospecting has accelerated countermeasure development or that systematically discovering novel #zoonotic viruses in animal hosts before they cause human outbreaks has been feasible.

medRxiv · What is the relationship between viral prospecting in animals and medical countermeasure development?In recent decades, surveillance in nonhuman animals has aimed to detect novel viruses before they 'spill over' to humans. However, the extent to which these viral prospecting efforts have enhanced preparedness for disease outbreaks remains poorly characterized, especially in terms of whether they are necessary, sufficient, or feasible ways to spur medical countermeasure development. We find that several viruses which pose known threats to human health lack approved vaccines and that known viruses discovered in human patients prior to 2000 have caused most major 21st-century outbreaks. With Filoviridae as a case study, we show there is little evidence to suggest that viral prospecting has accelerated countermeasure development or that systematically discovering novel zoonotic viruses in animal hosts before they cause human outbreaks has been feasible. These results suggest that prospecting for novel viral targets does not accelerate a rate-limiting step in countermeasure development and underscore questions about the importance of zoonotic viral discovery for outbreak preparedness. We consider limitations to these conclusions and alternative but related approaches to preparedness and response. ### Competing Interest Statement A.V.A. was an intern for CEPI in 2023 and is a consultant for Centivax, Inc.

Yes I confirm that all necessary patient/participant consent has been obtained and the appropriate institutional forms have been archived, and that any patient/participant/sample identifiers included were not known to anyone (e.g., hospital staff, patients or participants themselves) outside the research group so cannot be used to identify individuals. Yes I understand that all clinical trials and any other prospective interventional studies must be registered with an ICMJE-approved registry, such as ClinicalTrials.gov. I confirm that any such study reported in the manuscript has been registered and the trial registration ID is provided (note: if posting a prospective study registered retrospectively, please provide a statement in the trial ID field explaining why the study was not registered in advance). Yes I have followed all appropriate research reporting guidelines, such as any relevant EQUATOR Network research reporting checklist(s) and other pertinent material, if applicable. Yes Data used for this analysis are available in Supplementary Information.

“Among the study's findings, the researchers revealed that a 1 million ton increase in beef, chicken, meat, and pork production in a given year corresponds to an increase in disease outbreaks between 48% and 530 among certain flu pathogens within a country.”

We need to stop the slaughter-based meat industry’s efforts to increase our consumption of these products via public funding.

A(#H2N2) and A(#H3N2) #influenza #pandemics elicited durable cross-reactive and protective #antibodies against avian #N2 #neuraminidases, Nat Commun.: nature.com/articles/s41467-024

The anti-AIV N2 antibodies titers correlate with antibody titers to the 1957 N2, suggesting that #exposure to the A(H2N2) virus contribute to this reactivity. These findings underscore the critical role of neuraminidase #immunity in #zoonotic and pandemic influenza #risk #assessment.

NatureA(H2N2) and A(H3N2) influenza pandemics elicited durable cross-reactive and protective antibodies against avian N2 neuraminidases - Nature CommunicationsUsing more than 300 serum samples from individuals with an age range of 1-88 years old, the authors here show that older adults possess higher breadth of antibody reactivity to avian influenza virus (AIV) neuraminidases, potentially explaining the age-specific risks of AIV human infections.
