Chinese lab conducted extensive research on deadly bat viruses, but there is no evidence of accidental release

For nearly a decade, a team of scientists from Wuhan, China, crisscrossed southern Asia in a high-stakes search for bats and the strange diseases they harbor. They crawled through caves, catching the razor-toothed mammals with nets and scooping up liters of their excrement. They trapped insects and mice living near bat roosts and collected blood from villagers who hunt bats for food or folk medicine.

They returned to their state-of-the-art laboratory in central China with tubes and vials containing known killers — pathogens associated with diseases that are deadly in humans — and also a few surprises. On multiple occasions, their takings included exotic coronaviruses previously unknown to science.

The highlights of the Wuhan researchers’ work on bat viruses are spelled out in more than 40 published studies and academic papers that describe a sprawling, ambitious effort to document the connection between bats and recent disease outbreaks in China. The experiments were intended to illuminate how dangerous pathogens sometimes jump from animal hosts to humans. But experts say the research also carried an implicit risk: the possibility that the lab itself could facilitate the spread of the very diseases the scientists were trying to prevent.

On Thursday, the U.S. intelligence community released an assessment formally concluding that the virus behind the coronavirus pandemic originated in China. While asserting that the pathogen was not man-made or genetically altered, the statement pointedly declined to rule out the possibility that the virus had escaped from the complex of laboratories in Wuhan that has been at the forefront of global research into bat-borne viruses linked to multiple epidemics over the past decade.

Yet, despite the intense scrutiny, the novel coronavirus’s origins remain as murky now as they did when the first cases emerged in China five months ago. While intelligence analysts and many scientists see the lab-as-origin theory as technically possible, no direct evidence has emerged suggesting that the coronavirus escaped from Wuhan’s research facilities. Many scientists argue that the evidence tilts firmly toward a natural transmission: a still-unknown interaction in late fall that allowed the virus to jump from a bat or another animal to a human.

This lab that so happened to study viruses linked to bats has an outbreak start in the same community that the lab is located.

It doesn't take a tinfoil hat to at least extensively investigate the possibility. In fact, except for the the political power of China, we would already have our scientists conducting an extensive independent investigation if it was a small country without nuclear weapons. We wouldn't give them a choice.

...where woo-woo is standard operating procedure.

It is good science to study animal viruses that are known to transmit to humans. In fact, it's normal procedure, given that most flu viruses originate in China from birds and pigs.

Since it is believed that the SARS and MERS viruses originated in bats - a suspect organism in SARS-CoV2 also includes pangolins - a good prepared health team would very naturally be involved in studying these viruses.

At the same time, there's no way to distinguish between sloppy handling of unmodified virus samples in a lab and encountering the virus on the actual animal.

They're blocks away from each other. (Since it's a reciprocal relation, that makes sense, right?)

The lab has reportedly had accusations of sloppy handling and collection procedures.

Not sure it's a big deal, except that if it's a lab it makes the cover-up (slightly) more reasonable.

This of course, is necessary. We are not going to understand this virus and learn how to deal with it unless we have samples of live virus. My understanding is that the Chinese rapidly sequenced the viral RNA because they have very qualified people who know how to do it.

Having worked with dangerous materials myself, I assume that most people respect the materials with which they work for their own protection. At least they will if properly trained.

There are exceptions. For example I once worked in a lab where people were so afraid of radioactive materials that they simply allowed them to accumulate in hoods thus increasing their potential for exposure. I thus had to take responsibility for those materials myself, since I understood what they were and how they should be properly handled. In this American lab, training was poor. (After setting up systems to deal with it, I left the company.)

My overall impression of Chinese science is very positive. Roughly half of what I read in the journals that I regularly scan is written by Chinese scientists. There are linguistic artifacts in some of the writing, but in general, the science is of high quality. It is a mistake to assume that our labs and our scientists are superior, particularly because we increasingly hate science and scientists in this country and the Chinese, um, don't.

What we are seeing is that areas of high population density have the highest risk. It's not an accident that New York - mostly in the metropolitan area, New Jersey and Massachusetts have high rates of infection and death. Thus it's also not surprising that the disease traveled fast in Wuhan.

I am not entirely sure at this point, however that the Chinese government is being up front about the current rate of infection, but I do believe that Chinese scientists are doing an outstanding job in addressing the crisis on their level.

A country ruled by Trump has no right whatsoever to cast aspersions on any other country from a position of superiority. At least Xi is not telling people to drink drink bleach and shoot up Lysol.

things all the time.
After all you never know what new medical breakthroughs might be discovered through such research not to mention potentially detecting a problem virus beforehand.

Lack of evidence is not the same as evidence of the contrary.

If China hadn't been so absurdly secretive I would have been tempted to give them a pass. But Occam's Razor combined with their behavior certainly leads to some doubts.
