Some people have been pushing the idea that COVID-19 was artificially created in a Chinese lab. There’s no real evidence for that — the virus itself doesn’t contain any labels of its origin, that a research lab in China was studying the virus isn’t evidence of manipulation (a research lab researching is what research labs do), and the people promoting the ‘lab leak’ theory all seem to have a political agenda to blame someone. I sure haven’t been convinced. Now there’s a new revelation: they’ve found genetic evidence from samples collected at the Huanan wet market that infected wild animals were there.
Way back in 2019, researchers were swabbing locations in the market and filing away samples for later analysis. Guess what? It’s later. Swabs sampled from a stall that was selling raccoon dogs have been sequenced, and they’ve found … raccoon dog DNA, which is no surprise. But they also found lots of SARS-CoV-2 mingled with it, which tells us that these wild animals were already infected with COVID.
A new analysis of genetic sequences collected from the market shows that raccoon dogs being illegally sold at the venue could have been carrying and possibly shedding the virus at the end of 2019. It’s some of the strongest support yet, experts told me, that the pandemic began when SARS-CoV-2 hopped from animals into humans, rather than in an accident among scientists experimenting with viruses.
“This really strengthens the case for a natural origin,” says Seema Lakdawala, a virologist at Emory who wasn’t involved in the research. Angela Rasmussen, a virologist involved in the research, told me, “This is a really strong indication that animals at the market were infected. There’s really no other explanation that makes any sense.”
I’ve never been that interested in the question of its origin. I already know that we live on a planet of viruses, with an unimaginably huge population of diverse viruses squirting their DNA and RNA into every available creature, genetic material that is constantly mutating at a rapid rate, and what we ought to be amazed at is that we have molecular mechanisms of resistance, an immune system, that can cope with it at all. It was inevitable that something would evolve to get past our defenses, and that we’d have to adapt or die. That’s what we’ve been doing for the entirety of the existence of life on Earth.
That life changes and that there are naturally inimical forces that exist is an uncomfortable truth for many people. They’d rather think that a threat is by intent, that it had to be designed, and that the solution is to march out and do battle with a hostile, and purposeful, enemy (in this case, all of China. Good luck with that, I’d rather deal with it by improving public hygiene and developing new medicines.)
Now, can we stop wasting time looking for someone to blame, and refocus on dealing rationally with the pandemic? Unfortunately, there are many people who think the way to deal with a threat is to ignore it and pretend it has gone away. It hasn’t. The viruses keep on changing, thriving on the neglect that gives them an opportunity to proliferate in all these hosts who have given up, and it’s only going to get worse.
