Wildlife and Livestock a Risk Factor in Future Pandemics, Say Studies (theguardian.com) 60

The risk of pathogens spilling over from wildlife trade and farmed animals into humans should be key considerations in efforts to prevent the next pandemic, research suggests. From a report: Researchers have been assessing the risks of the different ways that disease-causing organisms jump from animals to humans in an effort to characterise and address the risk of the next pandemic. In a study published in the journal Biological Reviews, University of Cambridge scientists found that while the risk of another pandemic cannot be eliminated, systemic changes in the way we interact with animals, in general, could substantially minimise the probability.

The risks are not just linked to exotic wild animals, they caution. "There's a natural tendency, particularly in the western world, to imagine that this has nothing to do with us. It's something remote and exotic ⦠something that someone else has been doing," said the study's lead author Dr Silviu Petrovan, a veterinarian and wildlife expert at Cambridge. "I suppose what most people have in their minds is not the venison that they buy in Waitrose -- which, of course, is wildlife -- but rather something altogether more exotic."

    Seriously? Common knowledge if you ask me.

    • Is it though? Look how easily many bought into the idea that COVID-19 was bioengineered, despite the fact that it's been fairly well known since the 18th century that pathogens can jump between livestock and humans. The first real breakthrough in vaccination came when it was recognized that farmers getting a relatively minor infection from catching cowpox from their livestock conferred some degree of immunity against smallpox. Further, we've known for a long time that close proximity between humans and anim

      • yes, we get influenza and other viruses from animals circulating around the globe every year, it's common knowledge. Sometimes those turn into global pandemics, common knowledge. All educated people know that. I'm amazed a headline that spews the blatantly obvious about a known recurring thing exists on slashdot.

The first real breakthrough in vaccination came when it was recognized that farmers getting a relatively minor infection from catching cowpox from their livestock conferred some degree of immunity against smallpox. Further, we've known for a long time that close proximity between humans and animals (wild or domesticated) greatly increases the likelihood of inter-species transmission. In at least some cases, the reason that major pandemics came from Eastern Asia had to do with that region having a much higher population, again making proximity between humans and animals a potential vector, and then, with denser populations, once a pathogen has made the leap, greatly increasing the initial spread of the new strain.

        Evolution is an extraordinary thing, and in no other family of organisms does it happen faster than in viruses. It's virtually assured that so long as there are humans, there will be pathogens that evolve the capacity to infect us and then spread between us. Evolution is an arms race, and viruses, in particular RNA viruses, due to the fundamental instability of their genomes, will always have the edge.

        I don't eat Bat or Pangolin. I also don't eat "bushmeat"

        Most of what I eat is monitored and managed by federal agencies. Some chicken, pork and beef.

        If there are a whole ton of pathogens in that food, other than being trafficked to China for processing, and then back to the US, (which I try to avoid) then there really isn't anything I can do about it, other than buying and consuming locally sourced meat.

        • The possible origins of the 1918-19 influenza virus (H1N1) was waterfowl, with pigs as a possible intermediate species (pigs can be infected by avian flus, and thus can act as an intermediate between birds and humans). If you imagine the only way viruses can make the species leap is by eating bushmeat, you know woefully little about the subject.

      That's not enough. We also need to cook the people who caught/raised, traded, slaughtered, and handled the animals. Then we'll be golden.

        Also everyone in proximity to any sort of wildlife. Maybe automate food production and move everyone into domed cities, but only if you can keep out the rats and pigeons.

        • Keeping out the pigeons shouldn't be that hard, but rats have had several thousand years to learn how to keep out of sight. And, even if you manage to get rid of the rats, there's still the flies and cockroaches to deal with. Good luck with that!

        We had a couple cases in my province just recently. Increased testing due to COVID is probably the only reason they were noticed.

    • The trouble is in the steps involved in turning a live animal into cooked meat, this is where disease transfer can occur even if the meat is well-done. Another item to add to the long list of Problems With Farming. If we could replace livestock farming with artificial meat substitutes, it would directly solve a wide range of health and environmental issues, and might just improve a wide range of seemingly unrelated issues that come along with old-school farmers wielding large amounts of political power.

      • > If we could replace livestock farming with artificial meat substitutes

        Perhaps, but our understanding of human nutrition is too nascent to take on something like that now.

        Poor farming practices can definitely be a problem, but you're not seeing these from regenerative farms - just CAFO's and people living with animals.

        And the really bad pandemics don't result from a bat humping a pangolin then being made into soup. That's just the crap you have to hear from racists these days (yeah, you Daszak).

        • We can't be quite sure where the H1N1 strained started (though I have heard the Nebraska theory), but we do know that it originated as an avian influenza virus, that likely infected pigs (pigs are susceptible to avian influenza viruses), and from pigs it leapt to humans. And that's really the point. Some of the most significant pandemics in history were the result of humans living in close proximity to livestock and other animals endemic to human populations. The Black Death likely started in Asia with huma

    The airlines and the open-borders crowd aren't going to like it. And my bucket list of things to do in Italy might stay unfulfilled, but I think the real answer to mitigating the next one is that we have to say bye bye to casual international travel for pleasure and for business that need not be conducted face to face.

    School, work, immigration, they're long-term things that can probably remain in some form close to before, but popping over to the other side of the planet for christmas or Thanksgiving break or jetting over to Paris for fashion week might be no more.

      I don't know. The US is a big population pool and has a lot of climatic variation, with quite a few zoonotic diseases arising in the last couple decades. Better ban interstate travel and most commerce too.

      • I suppose we could weld everyone into their homes while we're at it, or we can recognize the distinction between freedom of movement within a country and crossing national borders and transcontinental travel.

          Gotta draw the line somewhere hey? And if practical criteria give you the wrong answer, there's good old fashioned xenophobia!

          Not that I'm opposed to the US isolating itself for a bit. Problem is, currently your half-vaccinated populace are screaming at us to let you into our country again.

          • If acrophobia has the effect of preventing you from testing the hypothesis that you can fly by leaping off a bridge, it's not all bad. If arachnophobia has the effect of lowering your probability of getting bitten by nasty spidery critters, it has its upsides. And if xenophobia has the effect of not seeding your country with a disruptive and costly disease outbreak every decade or so, then it's not all bad either.

              I guess you missed the implications of "if practical criteria give you the wrong answer."

              But I agree with you in principle! I think you're being kind of timid for writing off welding people in their houses, but I guess that does make it hard for them to work. Units the size of the US are useless. US state-size isn't great either, but maybe better than nothing.

      Or at least lock down air travel to the point where you have to stay in a quarantine zone. Incubation period is the biggest factor at play. But given a short enough incubation; mandatory, supervised, quarantine rooms need to be provided before releasing them. This likely will be somewhat generic and uncomfortable. A room with two doors, a hallway of potentially contaminated on one side, a verified clean on the other. You dont get to get released to the clean side until your quarantine stay is over and you t
      • The jury is still out on whether quarantine works at scale. It worked in Australia until it didn't.

        And your idea sounds good until you get into details: how do you avoid contamination on the dirty side when you're funelling all international arrivals into one spot?

        No...if I had to bet money on anything, I'd say that lowering the volume of casual travel would have more of an effect.

    The idea that we might get diseases from cows shouldn't alarm anyone. This is normal. We've done it lots before. And it has made us stronger and more resilient to viral infection overall.

  • Another dose of swine flu, anyone? That outbreak in an American factory farm south of the border in Mexico, presumably to evade health & safety regulations, was a mild one. More severe flus tend to come from birds, especially intensively farmed poultry, e.g. SARS, and now as we've seen, when humans invade wild areas inhabited by bats, e.g. ebola & COVID-19. Apparently, the ebola outbreak in Liberia was most likely caused by farm workers slashing their way into wild jungle to make way for palm oil pl
