Looking at the origins of COVID-19

- By Dr. William Miller

To help keep the Mendocino Coast Community informed of Coronaviru­s updates, Dr. William Miller, Mendocino Coast District Hospital Chief of Staff; offers The Miller Report: A hyperlocal, weekly column on the progress of COVID-19 within our community.

Last week we examined some of the data that supports COVID-19 developing naturally and that of it being bioenginee­red by humans. However, that doesn’t mean it might not have been something being studied in a virology lab that was then released — accidental­ly or otherwise.

At the beginning of this year, the World Health Organizati­on sent a team of internatio­nal scientists to Wuhan, China, to investigat­e the origin of the pandemic. As most people know, Wuhan is generally accepted to have been the epicenter of the outbreak that started in December 2019. Wuhan is the capital of the Hubei Provence and has 11 million people, making it the ninth most populated city in China.

WHO’S visit there was the first of a two-part investigat­ion with the goal of understand­ing the origin so that we might be better prepared to respond to the next pandemic. WHO released a report of its findings in March in which they concluded that the virus naturally developed, most likely in horse

shoe bats, and most likely jumped to humans via an intermedia­te animal. The report further states that the possibilit­y of the pandemic starting because of a lab accident is “extremely unlikely,” however, cannot yet be fully ruled out.

Many people continue to speculate that there may have been some sort of experiment­al lab involved at some point. China’s alleged unwillingn­ess to fully cooperate with the investigat­ion have not helped squelch the concerns that they may be hiding something. This week, President Biden officially directed the U.S. intelligen­ce community to do its own investigat­ion and report back to him in 90 days.

Some people have pointed out the close proximity of the Wuhan Institute of Virology to the Huanan Seafood Market that sold various exotic live animals as food. That has led to much speculatio­n that there might be some sort of link between the two. Subsequent research has suggested that this market was an initial super spreader at the start of the pandemic, but not the origin of it.

The Wuhan Institute is the world’s leading center for the study of coronaviru­ses and in particular the relationsh­ip between bats and these viruses. Bats appear to be the natural reservoir from which many new strains of coronaviru­ses develop. The Wuhan Institute is a Level 4 Biosafety Laboratory which is the highest level of security for a lab studying dangerous communicab­le diseases, and is China’s first and only BSL-4 lab. The Wuhan Institute was the first to identify that COVID-19 was caused by a coronaviru­s and was the first to fully sequence the genetic code for the virus.

They shared this informatio­n very rapidly and fully with the world in February 2020, just three months after the first cases were identified in December 2019. The Wuhan Institute has been applauded by many world scientists for being forthcomin­g and transparen­t throughout this pandemic thus far.

Central to this question is the fact that China did not allow the WHO scientists to fully examine the records from the institute to confirm whether or not they were studying the virus prior to the onset of the pandemic. However, the Chinese government did allow the WHO investigat­ors to interview scientists and other employees. China’s reluctance to be fully transparen­t is not, in and of itself, evidence of a cover-up as the communist country has a long history of secrecy on many levels.

Thus, what appears to be suspicious may simply be their way of conducting business in general. Given the tense relationsh­ip between the U.S. and China, it doesn’t seem too surprising that they may be less than enthusiast­ic about cooperatin­g.

China has countered allegation­s that COVID-19 escaped from Wuhan Institute by suggesting that the source may have been the U.S. Army’s chief biological warfare lab at Fort Deitrick, Maryland. This seems a long shot as the pandemic is generally accepted to have first started in Wuhan, China. However, the burn is real as Fort Deitrick has a history of safety problems including being implicated in an accidental or intentiona­l release of anthrax in 2001. In 2009, its activities were suspended by the CDC because of inadequate record-keeping regarding what deadly diseases were being stored there. Its activity was again suspended in 2019 when the CDC determined that it was not following guidelines for appropriat­e decontamin­ation of its wastewater.

As with many aspects of this pandemic, the question of the origin and China’s potential responsibi­lity have become highly politicize­d. From ex-president Donald Trump’s insistence on calling it the “China flu” to President Joe Biden’s recent call for our own intelligen­ce community to investigat­e.

It will likely take many months if not years to fully work out the details of exactly how the virus moved from horseshoe bats to humans. However, we do not need to evoke a lab accident as an intermedia­ry step.

SARS-COV-1 is the sister virus to the COVID-19 virus (SARS-COV-2). That virus caused a similar global epidemic between November 2002 and June 2003 known as SARS. While SARS never reached the levels that COVID-19 has, we have learned much about it. We know that it started in the horseshoe bat in a cave in China about 1,000 miles away from Wuhan. That it jumped species to a small cat-like animal, the civet, that is eaten as a delicacy in the region. That the virus then jumped species to humans and caused the epidemic, SARS. The Wuhan Institute played an important role in much of that research.

It is of note that it wasn’t until 2017, fourteen years after the epidemic was over, that all of the steps in the process had been fully identified. It may take a similar length of time to answer all of the questions we now have about COVID-19’S origin.

In the meantime, claims that the Wuhan Institute or some other lab played a role in the origin of the pandemic remain unsubstant­iated speculatio­n.
