Daniel sent us this one, and it's effectively two questions wrapped in a personal observation. The first is: what actually happened with the COVID origin investigation? Did we ever get a definitive answer, or did the whole thing just dissolve into the fog of other crises? And the second is about wet markets themselves — specifically the wildlife wet markets — what makes them such potent pandemic incubators, and did China's ban on them actually stick?
Right, and those are both excellent questions, and they connect in ways that most of the coverage at the time didn't really pull together. The origin question and the wet market question are not the same question, but they overlap in this one specific place that ended up being the center of the entire debate.
Let's start with the origin investigation, because I think the prompt is right — there was this enormous public argument for about two years, and then it just sort of evaporated without most people ever hearing a conclusion.
It evaporated because the investigation effectively hit a wall, but not before producing some genuinely substantive findings. The key document here is the WHO-convened global study that was published in March of twenty twenty-one. This was a joint effort between the WHO and Chinese scientists, and it was the result of a team actually traveling to Wuhan and spending time there. And the report landed on what they called a likely to very likely zoonotic origin — meaning the virus jumped from animals to humans — with an intermediate wildlife host as the probable bridge.
Which is the scientific way of saying we think it came from a bat, passed through some other animal, and then into humans. But that's not a definitive answer.
No, it's a probability assessment, and the report was very careful about that. It ranked four scenarios. Scenario one: direct zoonotic spillover from a bat or other reservoir host. Scenario two: introduction through an intermediate host, which they considered likely to very likely. Scenario three: introduction through cold-chain food products, which they considered possible. And scenario four: a laboratory incident, which they considered extremely unlikely.
That last one is where everything went nuclear, because the extremely unlikely label was immediately contested by a lot of very serious scientists who said the WHO team didn't have full access, couldn't interview all the relevant people, and essentially took Chinese government data at face value.
That's the crux of it. The WHO team spent time in Wuhan, they visited the Huanan Seafood Market, they visited hospitals, they reviewed epidemiological data. But they were not given unrestricted access. They couldn't interview every researcher at the Wuhan Institute of Virology. They couldn't independently verify all the data they were given. And the Chinese government was heavily involved in shaping the terms of the investigation. So you end up with a report that says something, but the international scientific community immediately said, well, we need to see the underlying data, and we never really got it.
Where did the investigation go after that report?
The WHO continued to push for a second phase of the investigation, and China essentially refused. There was a lot of diplomatic back and forth. In June of twenty twenty-two, the WHO's director-general, Tedros, said publicly that the investigation was stalled and that China had not shared the necessary information. Meanwhile, you had independent efforts. The Lancet commission published a major report. Various national intelligence agencies produced their own assessments. intelligence community released a declassified assessment in twenty twenty-three that said they couldn't determine the origin but that both a natural spillover and a laboratory-related incident were plausible.
The official U.position is we don't know.
We don't know. And that's where it's been stuck. The scientific consensus, if you survey the relevant experts, leans toward zoonotic spillover — probably involving the Huanan market, probably involving raccoon dogs or similar species that were being sold there. But it's a consensus with a giant asterisk that says we haven't been able to verify the lab side of the equation independently. And until China allows that verification, the question remains open.
The definitive answer the prompt is asking for — it doesn't exist. What exists is a heavily caveated scientific leaning with a political blockade around it.
And I think that's why it faded from public discussion. There was no new information to report. The story became the lack of access, which is a diplomatic story, not a scientific one, and those don't hold public attention the same way. Plus, you had the war in Ukraine, then the Iran situation, then inflation, then a hundred other things. The origin question just got crowded out.
There's one piece of this that I think is worth pulling on, because it connects directly to the second part of the prompt. The Huanan Seafood Market. That's the wet market that became ground zero for the investigation. And that market was selling live animals.
Yes, and this is where the distinction in the prompt is important. The prompt says wildlife wet markets, not just wet markets. A wet market is a market that sells fresh produce, meat, fish, and sometimes live animals — the wet refers to the water and ice used to keep things fresh. They're common across Asia, and they're not inherently dangerous. A wildlife wet market is a different thing. That's where you're selling live wild animals — civets, raccoon dogs, pangolins, bamboo rats, snakes, various bird species — often in cages stacked on top of each other, often with animals that would never interact in nature being held in close proximity.
That's the pandemic incubator part.
The mechanism is called zoonotic spillover, and wildlife wet markets are essentially designed by accident to maximize the probability of it happening. Let me walk through why. You have a virus circulating in a wild animal population — bats are the classic reservoir because they have these incredible immune systems that tolerate viruses without getting sick. That virus is shedding in the bat's saliva, urine, feces. Now you bring that bat, or an animal that's been in contact with bats, into a market. You put it in a cage. Below that cage, you have raccoon dogs. Next to it, you have civets. The virus drips down, or it's aerosolized, or it's on the hands of the vendor who handles multiple species. Now you've got a virus that's evolved to infect bats suddenly finding itself in a raccoon dog.
Raccoon dogs are not bats.
They are not bats. They're canids. They're more closely related to dogs and foxes. But they're mammals, and they have similar cellular receptors in many cases. The virus doesn't necessarily infect them efficiently at first, but it gets a chance to try. And if it manages to replicate even a little bit, it starts adapting. Every replication cycle is an opportunity for mutation. One of those mutations might make it better at binding to the ACE2 receptor in the raccoon dog. Another might make it better at evading the raccoon dog's immune system. And now you've got a virus that's taken one step away from being a bat virus and one step toward being a mammalian virus that could potentially infect humans.
The market is a kind of evolutionary accelerator. You're compressing interactions that would take decades or centuries in the wild into a few days in a cage stack.
That's a very good way to put it. And it's not just the animals. You've got human vendors handling these animals, butchering them, cleaning up blood and waste. You've got customers walking through, breathing the air, touching surfaces. The density of human-animal contact in these markets is extraordinary. One study from twenty twenty-one estimated that wildlife wet markets in China bring tens of millions of people into contact with thousands of wild animal species every year. That's a lot of lottery tickets for a pandemic.
This isn't the first time.
Not even close. SARS in two thousand two, two thousand three — that jumped from bats to civets to humans, and the civets were being sold in wildlife markets in Guangdong. The initial cases were traced to a market in Foshan. MERS, Middle East Respiratory Syndrome, that went from bats to camels to humans. Ebola is suspected to have involved bats and possibly intermediate hosts in bushmeat markets in Africa. The pattern is so consistent that it's almost a law of epidemiology at this point.
The prompt asks whether the close interaction of species that wouldn't normally interact is the accepted cause. And the answer is yes, but with layers. It's not just the interaction. It's the interaction plus the stress on the animals, which increases viral shedding. It's the poor sanitation. It's the repeated human exposure. It's the fact that you're bringing animals from different ecosystems — a bat from a cave in Yunnan, a civet from a forest in Guangxi — and putting them in the same physical space.
There's one more layer that I think is underappreciated. These markets don't just sell live animals. They slaughter them on site. So you've got blood, you've got viscera, you've got aerosolized particles from the butchering process. If you're a virus looking for a way into a human respiratory tract, you couldn't design a better scenario than a person leaning over a freshly killed animal, breathing in whatever's coming off the carcass.
It's the viral equivalent of a speed-dating event with very poor hygiene.
That's a Herman-level analogy right there. And the thing is, this isn't a secret. The scientific community has been warning about wildlife wet markets as pandemic risks for decades. There were papers published in the early two thousands after SARS saying, we need to regulate these markets or we're going to see another outbreak. And then we got COVID, which was orders of magnitude worse than SARS.
Which brings us to the second half of the prompt's question. China banned wildlife trade and wet markets. Did it stick?
Here's the timeline. In late January twenty twenty, as COVID was spreading, China announced a temporary ban on wildlife trade. A month later, in February twenty twenty, the National People's Congress issued a decision to comprehensively ban the trade and consumption of wild animals. This was a big deal — it was framed as a permanent, comprehensive prohibition. The language was strong. Eating wild animals was banned. Hunting, trading, and transporting wild animals for consumption was banned. There were exceptions for fur, for traditional medicine, for scientific research, but the core message was: the wildlife wet market era is over.
Then reality happened.
Then reality happened. Enforcement is hard. China has a vast country with deeply embedded cultural practices around wildlife consumption, particularly in the south. There's a traditional belief that eating wild animals has health benefits — it's called yewei, which means wild taste, and it's associated with vigor and status. You don't erase that with a legislative decision. What you get is a shift from open markets to underground trade.
The markets came back, just less visible.
It's more nuanced than that. The major, high-profile wildlife markets — the ones that international media could point a camera at — those were largely shut down and stayed shut down. The Huanan market in Wuhan was closed permanently. But smaller-scale wildlife trade continued. There have been multiple reports from environmental groups — the Environmental Investigation Agency, the Wildlife Conservation Society, various academic researchers — documenting ongoing wildlife trade in China in the years since the ban. A twenty twenty-three report found that wildlife was still being sold in markets across multiple provinces, sometimes openly, sometimes under the counter.
Under the counter meaning they just stopped displaying it but still had it.
The term of art is cryptic trade. You ask the vendor, the vendor checks that you're not law enforcement, and then they bring out the bamboo rats from the back. Or the trade moves online, through social media and messaging apps. WeChat becomes the marketplace. And that's much harder to police than a physical market.
The ban was real, it had teeth on paper, it closed the most visible markets, but it didn't eliminate the practice.
I think this is where the prompt says I will reserve my judgment for the facts, and I appreciate that, because the facts are complicated. China did more than most countries would do in response to a pandemic originating in wildlife trade. They passed a national law. They arrested people. They seized animals. They ran public awareness campaigns. But the gap between legislation and compliance in a country of one point four billion people with a long history of wildlife consumption is enormous.
There's an economic dimension here too, isn't there? Wildlife trade is a livelihood for a lot of people.
We're talking about rural communities, often in poorer regions, where trapping and selling wild animals is a significant source of income. If you ban the trade without providing alternative livelihoods, you're basically telling people to choose between breaking the law and feeding their families. That's not a choice that enforcement alone can solve. You need economic transition programs, and those take time and money and political will.
The situation now, in twenty twenty-six, is that the official wildlife wet markets of the kind that spawned COVID are largely gone, but the wildlife trade itself has fragmented and gone underground, and the underlying conditions that make spillover possible haven't fundamentally changed.
That's my read of the evidence. And I should say, I'm not sure about the exact current state of enforcement — it's been a while since there was a major English-language investigative piece on this — but the structural incentives haven't shifted. Demand for wild meat still exists. Poverty in rural trapping communities still exists. The profit margin on a pangolin or a civet is still very high relative to local wages. As long as those conditions hold, the trade will find a way.
Which is a deeply unsatisfying conclusion, but I think it's the honest one.
It is unsatisfying. And it connects back to the origin question in a way that I think is important. Whether COVID came from a wildlife market or a lab — and again, the evidence leans toward the market but hasn't been fully verified — the fact is that wildlife wet markets represent a standing risk of future pandemics. Even if this particular virus came from somewhere else, the next one could come from a market. The one after that almost certainly will, if the pattern holds.
The prompt's instinct that ignoring this would be a terrible way to respond to what happened — that instinct is correct. But the question is whether the response has actually addressed the risk or just made it less visible.
I think the honest answer is that it's made it less visible. The international community moved on. The media moved on. The political pressure that existed in twenty twenty and twenty twenty-one to do something about wildlife markets globally — that pressure has largely dissipated. There were some international efforts. The WHO and the World Organization for Animal Health put out guidance. There were discussions about a global pandemic treaty that would include provisions on wildlife trade. But those negotiations have been slow and contentious.
The pandemic treaty — what actually happened with that?
It's been in negotiation since twenty twenty-one under the WHO. The idea was to create a legally binding international agreement on pandemic prevention, preparedness, and response. One of the sticking points has been exactly this — the wildlife trade provisions. Countries that have significant wildlife trade industries have pushed back against binding restrictions. There's a sovereignty argument, there's an economic argument, and the negotiations have dragged on. As of the latest updates I've seen, there's a draft text but no final agreement, and several key provisions have been watered down.
The global response to the thing that killed millions of people and trillions of dollars in economic output is a draft text with watered-down provisions.
That's the nature of international diplomacy. It moves slowly, and it's subject to the same political and economic forces as everything else. The urgency of twenty twenty has faded, and with it, the political capital to do hard things.
There's something darkly funny about that. A virus doesn't care about your negotiation timeline. It doesn't wait for the next session of the intergovernmental negotiating body. It just needs a bat and a raccoon dog and a human within sneezing distance.
That's the core tension. The incubation period for a pandemic is measured in days. The incubation period for international law is measured in years. Those clocks don't match.
Let me pull on one thread from the prompt that we haven't touched yet. The prompt mentions the mRNA vaccines and how that story was inspiring — scientists laboring under underfunding for years, and then suddenly producing a technology at record pace that saved a huge number of lives. And I think that contrast is worth sitting with for a moment.
On one side, you have this incredible human achievement — decades of basic research into messenger RNA, work that was considered a scientific backwater by a lot of people, Katalin Karikó getting demoted at Penn because she couldn't get grant funding, and then in the space of about eleven months, that research becomes the foundation for vaccines that prevent something like twenty million deaths in the first year alone. That's the best of human ingenuity.
Karikó and Drew Weissman. They won the Nobel Prize in twenty twenty-three for that work. And you're right, Karikó's story is almost a parable — she was literally kicked out of her lab, she had to retire early, she was doing the work on the margins, and she just kept going because she believed in the science.
And then on the other side, you have the thing that made the vaccines necessary — a wildlife market, or a lab, or whatever the origin turns out to be — but fundamentally a failure of prevention. We knew about the risk. We had SARS as a warning shot. We had MERS. We had multiple near-misses with avian influenza. And we still didn't put the safeguards in place. So you get this perverse dynamic where we underinvest in prevention, we underinvest in basic research, and then when the crisis hits, we scramble and the same underfunded scientists pull off a miracle. And we celebrate the miracle, which we should, but we don't fix the prevention gap.
This is the preparedness paradox. If prevention works, nothing happens, and nobody sees it, and the funding gets cut because it looks like you're solving a problem that doesn't exist. If prevention fails, you get a catastrophe, and then you throw money at response, and then eventually the memory fades and you cut prevention funding again. It's a cycle.
We're in the fading-memory phase of the cycle right now.
We are absolutely in the fading-memory phase. If you look at pandemic preparedness funding globally, it spiked in twenty twenty and twenty twenty-one and has been declining since. The Coalition for Epidemic Preparedness Innovations, CEPI, which was a major funder of vaccine development, has been struggling to secure long-term funding. The WHO's pandemic fund is undercapitalized. The political momentum for the pandemic treaty is flagging. And wildlife wet markets — the specific thing we're talking about — that's just one piece of a much larger preparedness puzzle, and it's not the piece getting the most attention.
Because it's not a technological solution. It's a regulatory and cultural one. And those are harder to fund, harder to implement, harder to measure.
You can't put a wildlife trade ban in a press release with a shiny logo and a ten-figure budget and call it innovation. It's grinding, unglamorous enforcement work in rural markets. Nobody wants to fund that. Nobody wants to implement that. It's the public health equivalent of sewer maintenance.
The glockenspiel of pandemic preparedness.
I don't know what that means, but I think I agree with it.
It means it's not the thing anyone came to see. Nobody goes to the orchestra for the glockenspiel. But if you take it out, something essential is missing.
That's actually perfect. Wildlife market regulation is the glockenspiel of global health security. I'm using that.
To pull this back to the prompt's questions. Question one: was the cause of COVID definitively identified? The evidence strongly points to zoonotic spillover, probably involving the Huanan market, probably involving an intermediate host like raccoon dogs. But definitive proof is missing because China has not provided full access to the relevant data and sites. The lab leak hypothesis has not been ruled out, though it is considered less likely by most scientists in the field. The investigation is effectively stalled, and it's not clear when or if it will resume.
That's an accurate summary. The one thing I'd add is that the lack of a definitive answer is itself a significant finding. The fact that we cannot get a definitive answer, five years after a pandemic that killed millions, is a failure of international cooperation and transparency. The origin of COVID is a scientific question that has become a geopolitical hostage.
Question two: what makes wildlife wet markets such potent pandemic incubators, and did China's ban work? The potency comes from the concentration of species that would never interact in the wild, the stress on the animals that increases viral shedding, the poor sanitation, the on-site slaughter that aerosolizes pathogens, and the repeated close contact with humans. It's a perfect storm for zoonotic spillover. And the ban — it closed the most visible markets, it changed the legal landscape, but it didn't eliminate the trade. It pushed it underground, online, and into less visible channels. The underlying risk remains.
I think the underlying risk is the real takeaway here. Whether or not COVID specifically came from a wildlife market, the next pandemic could. The one after that could. As long as we're bringing wild animals and humans into close contact at scale, we're rolling the dice. And the dice have a lot of sides, but eventually they come up pandemic.
There's a statistic I remember seeing. Some researchers estimated that there are something like half a million undiscovered animal viruses that could potentially infect humans. Half a million. We've identified a tiny fraction of them.
That number comes from a twenty eighteen study in Science, and it's an estimate, but the order of magnitude is probably right. The virosphere is vast and mostly unknown. Every time you bring a new wild animal into a market, you're sampling from that unknown pool. Most of those viruses won't be able to infect humans. Most of the ones that can won't be highly transmissible. But you only need one.
One virus, one market, one unlucky interaction, and the whole world changes. It's almost comic in its disproportionality.
It's the butterfly effect, but with pathogens. A bat defecates on a raccoon dog in a cage in Wuhan, and eighteen months later, the global economy has lost trillions of dollars and millions of people are dead. The gap between cause and effect is so vast that it's hard for the human mind to hold it.
Which is probably why we don't act on it. The cause feels small. The effect feels like it came from nowhere. So we treat it as an act of God rather than a preventable risk.
That's the trap. COVID was not an act of God. It was a predictable outcome of specific human behaviors and systems. We knew the risk. We had the playbook. We just didn't execute.
The prompt mentions living in Israel, and I think there's an interesting parallel here. Israel was actually one of the better performers in the early pandemic response in some respects — the vaccine rollout was fast, the digital health infrastructure was strong. But the prompt also mentions that the last few years have felt like a blur of crises, with the wars and everything else. And I think that's true for a lot of places. The pandemic didn't end so much as it got eclipsed.
That's a really important point. The pandemic didn't end with a declaration of victory. It ended with a shift of attention. COVID is still circulating. It's still killing people, though at much lower rates thanks to immunity and treatment. But the public narrative moved on. The crisis became background noise. And when that happens, the political will to do the hard prevention work evaporates.
Because prevention requires you to sustain attention on something that isn't currently hurting you. And human attention is a scarce resource, especially when there's a war, or an economic crisis, or whatever the next emergency is.
That's the fundamental challenge of pandemic preparedness. You're asking people to care about something that hasn't happened yet, based on a risk that feels abstract, and to spend money and accept restrictions that have immediate costs. Politically, that's almost impossible to sustain.
Unless you've just lived through a pandemic. And even then, the window is maybe two or three years before the memory fades.
We're seeing that play out in real time. The window is closing, if it hasn't closed already.
Where does that leave us? The prompt is asking for the facts, and I think we've laid them out. But the subtext of the prompt is: did we learn anything? And I'm not sure we did.
I think we learned a lot scientifically. The mRNA platform is a genuine breakthrough that will change how we respond to future outbreaks. The genomic surveillance infrastructure is vastly better than it was in twenty nineteen. We have better tools. But did we learn institutionally? Did we learn politically? I'm less confident.
The tools got better. The wisdom didn't.
That's a Corn line if I've ever heard one. And I think it's right. The tools are incredible. We can sequence a new virus in days. We can design a vaccine candidate in hours. We can manufacture at scale in months. That's science fiction compared to where we were twenty years ago. But the wisdom to use those tools — the wisdom to invest in prevention, to regulate risky practices, to cooperate internationally — that's lagging.
The wildlife wet markets are the perfect case study of that gap. The science tells us exactly what the risk is. The solution is straightforward — regulate the trade, enforce the regulations, provide alternative livelihoods, reduce demand. The tools exist. The knowledge exists. What's missing is the political and institutional will to actually do it.
Let's not forget the money. Regulating wildlife trade across a country the size of China, or across Southeast Asia, or across Africa — that costs real resources. Inspectors, veterinarians, testing facilities, alternative livelihood programs, public education campaigns. The price tag is substantial. And nobody wants to pay it for a pandemic that might happen someday.
Even though the pandemic that did happen cost something like twelve to fifteen trillion dollars globally by most estimates. The math is not subtle. Spend billions to save trillions. But we don't do it because the billions are now and the trillions are later.
It's a well-documented cognitive bias. We value the present disproportionately over the future. A dollar today is worth more to us than ten dollars in ten years, even though rationally the ten dollars is better. And when you scale that up to national budgets and political cycles, you get systematic underinvestment in prevention.
The answer to the prompt, in the most compressed form, is: no, we never got a definitive answer on the origin, and we probably won't. Yes, wildlife wet markets are pandemic accelerators for exactly the reasons described. No, China's ban didn't fully work, and the trade continues in less visible forms. And no, we haven't really learned the institutional lessons, even though the scientific ones are remarkable.
That's a fair summary. I'd add one note of partial optimism. The fact that we're even having this conversation, the fact that wildlife wet markets entered the global lexicon, the fact that there are international negotiations happening — that's not nothing. In two thousand three, after SARS, the conversation about wildlife markets was mostly confined to a small group of epidemiologists and conservation biologists. Now it's a matter of public discourse. The Overton window has shifted on what's considered acceptable risk in the wildlife trade.
That's true. The awareness is orders of magnitude higher than it was. Whether awareness translates into action is the open question.
It's the only question that matters at this point.
Now: Hilbert's daily fun fact.
Hilbert: In the nineteen twenties, a French expedition to the Gobi Desert discovered that the axolotl's ability to regenerate limbs produces a faint bioelectric acoustic signature — a crackling sound at approximately forty hertz — that researchers at the time believed might be amplified and used to map regeneration patterns in other vertebrates, though the equipment of the era was too crude to verify the hypothesis.
That's barely above the lower threshold of human hearing. You'd feel it more than you'd hear it.
I don't know what to do with that. A crackling axolotl in the Gobi Desert. Hilbert, that's...
This has been My Weird Prompts. Thanks to our producer, Hilbert Flumingtop, for that deeply specific fact. If you enjoyed this episode, we'd love a review wherever you listen — it helps other people find the show. I'm Corn.
