Let evidence, not talk radio, determine whether the outbreak started in a lab

The president and his secretary of state made a startling claim last week: that there is enough evidence to suggest with a high degree of confidence that the Wuhan Institute of Virology is the source of the SARS-CoV-2 pandemic.

That declaration followed a frenzy of activity of cable TV and talk radio. On April 15, Fox News reported that sources believe patient zero worked at the laboratory and then went into the population in Wuhan. The next day, Rush Limbaugh ran an episode of his show titled “All the Coronavirus Taboos You Can’t Talk About” in which he reiterated the patient zero-Wuhan lab theory. Several days after that, Rudy Giuliani pushed the connection on his radio show where his guest even proposed that the subsequent spread of the virus to other countries was a malicious and deliberate act by China.

A week after that, President Trump would make his announcement.

The only problem is that neither the intelligence nor the science supports the claim.

The Office of the Director of National Intelligence which oversees the work of all 17 intelligence agencies issued a statement indicating that it is still studying “whether the outbreak began through contact with infected animals or if it was the result of an accident at a laboratory in Wuhan.

During a recent confirmation hearing, both Senate Intelligence Committee member Angus King and Director of National Intelligence nominee John Ratcliffe indicated they had not seen intelligence to suggest that the outbreak began in a laboratory.

Intelligence coming from allied nations threw more cold water on the notion, indicating that it’s “highly unlikely” that the coronavirus outbreak was spread as a result of a laboratory accident.

Beyond the lack of intelligence to support it, the notion is also unsupported by scientific experience.

While the Institute of Virology in Wuhan does conduct research on deadly coronaviruses—as do numerous other facilities around the globe—the odds of an accidental release from the lab are far lower than the odds of transmission on the outside.

That’s because far fewer individuals come into contact with coronaviruses in a laboratory setting, as opposed to those outside the lab who regularly come into contact with horseshoe bats that carry coronaviruses.

That includes villagers living in the proximity of caves in Yunnan, China—the source of the original SARS virus in 2002. They not only come into contact with bats that harbor coronaviruses related to SARS, but have even been shown to be infected by them.

Even if safety was substandard at the Wuhan Institute of Virology, as suggested by State Department cables, any protective gear and laboratory safety training is better than none—which is what those on the outside that come into contact with bats have protecting them.

That’s why scientists have been sounding the alarm for years that these exposures in natural settings could cause the next SARS-like pandemic.

Then there are all of those individuals who traffic in wild animals and those who purchase and consume them. Much has been said on how not all of the early cases of SARS-CoV-2 can be traced to the Huanan seafood market. But that doesn’t preclude the possibility of transmission from other markets and other sources in Wuhan.

The lesson to be learned here is that the transmission of pathogens from animals to humans is a regular occurrence and that we need to conduct more disease surveillance, globally, to find viruses at their source and to stop their spread.

In addition, we must be vigilant about restricting wild animal trade. It is inexcusable that China, despite knowing that the 2002 SARS outbreak originated in bats, continued to allow trade in bats and other wild animals.

Our leaders ought to learn from these mistakes and take steps to prevent the next pandemic, instead of diverting our attention to unsupported sensationalist theories spread by cable TV and talk radio.

There are at least three categories of experts whose views are critical to understanding the likelihood of a lab leak causing an outbreak: 1. Virologists 2. Experts in biosecurity / experts in complex systems failures. See Charles Perrow’s book “Normal Accidents” https://en.wikipedia.org/wiki/Normal_Accidents 3. Mathematicians (experts in probability) The lab leak theory is best evaluated at the intersection of the three. However, many media outlets are relying heavily on the opinions of the first category — virologists. And I would add to the above list: 4. Experts on China, the Chinese political system including how and to what extent information and… Read more »

Your logic is flawed. If this virus came directly from a bat that inhabited a cave in the Yunnan province (as its similarity to ratg13 suggests) then there is a very good chance that the researchers at the WCDC and the WIV tipped the scales , in terms of exposures, by going into those caves without the proper protection (documented in the WCDC marketing video and Wuhan news report featuring the WCDC lab worker) , and using substandard safety practices while studying the virus in a lab. SARS escaped the Beijing lab twice…and…they knew what it was. If the WCDC… Read more »

Laboratories grow viruses so concentrations may be higher than in the natural environment. That increases risks if release. Furthermore, a laboratory may or may not know if a release occurred. It is entirely possible that nobody will ever know what happened, including the Chinese. Manmade chemicals, modified viruses, and radionuclides leave evidence that allows tracking releases to the source. A natural virus does not leave such a trail of evidence.

While considering whether the SARS-CofV-2 virus came from a lab, don’t overlook are own demonstrably leaky biodefense (sic) lab at Ft. Detrick, which was closed down by the CDC last July for violating safety procedures, any one of which violations could have resulted in a lab workers being infected. If the worker was asymptomatic, the lab wouldn’t have even known there had been a leak, at least not until COVID-19 became a four-letter word.

I think Krem is correct. If it was an accidental, perhaps unsuspected, release, it will be next to impossible to prove. The accidents and mishaps that have occurred in US labs make it clear that there isn’t a 100% fool-proof system in place even in purportedly well-run labs.
