OPEN LETTER
April 7, 2021
CALL FOR A FULL INVESTIGATION INTO THE ORIGINS OF
COVID-19
Understanding how the SARS-CoV-2 virus emerged and spread to humans is an essential
foundation for prioritizing future pandemic prevention and response strategies. Yet well over a
year after the initial outbreak, no robust process for examining the origins of the pandemic has
been established and critical records and biological samples that could provide essential insights
into pandemic origins remain inaccessible. These shortcomings pose a significant threat to
everyone and future generations.
As scientists, social scientists, and science communicators, including signatories of the March 4,
2021 open letter on COVID-19 origins, we believe there is a better way forward.
- Reaction to the China-WHO joint study team report -
In our previous open letter, we outlined our fears that the joint international
committee/Chinese government team “did not have the mandate, the independence, or the
necessary accesses to carry out a full and unrestricted investigation into all the relevant
SARS-CoV-2 origin hypotheses.” Having read the report entitled ‘WHO-convened Global Study of
Origins of SARS-CoV-2: China part’ and reviewed the statements made in the March 30, 2021
WHO-organized press event announcing the report’s release, we have regrettably concluded
that our concerns were fully justified.
In addition to the issues regarding the joint mission structure and process outlined in our
previous open letter, we wish to express the following concerns regarding the joint study
process and report conclusions:
●The joint study team saw its priority as seeking a zoonotic origin, not as fully examining
all possible sources of the pandemic. Its Terms of Reference did not mention any
possible lab-pathway and on the contrary explicitly stated a strict zoonosis origin from
the very start (“identify the zoonotic source of the virus”).
1/9
●The published data supporting the mission report mostly present reviews of Chinese
studies that have not been published, shared with, or reviewed by the international
scientific community.
●Well over a year after the initial outbreak, critical records and biological samples that
could provide essential insights into pandemic origins remain inaccessible. This
withholding of key resources that could and should have been made available
undermined the credibility of the joint study team work.
●The joint study team used different evidentiary standards for the four origin theories it
considered. No solid justification is provided for why a ‘lab-related accident’ (whether a
lab-leak or sampling accident) should be considered ‘extremely unlikely’, or why a
natural spillover via an unknown animal host should be considered ‘likely to very likely’.
At this stage there is still no direct evidence for either pathway nor any verified data or
evidence sufficient to rule any one out, while historical evidence amply supports both.
●In particular, a primary conclusion of the report, that SARS-CoV-2 was most probably
introduced into the human population through an intermediate host, is not supported
by the negative results of all the 80,000 tested samples of wildlife, livestock (35 species)
and poultry. That pathway remains entirely theoretical, which at the very least shows
the necessity to remain open to other pathways.
●The joint study report spends a mere 440 words examining the lab-accident pathway -
less than 1% of the whole report - and does so in a dismissive and superficial way
without considering all the possible versions of that pathway, including a possible
infection of a sampling team member by a virus that may never have been isolated or
sequenced. The joint study report also makes no mention of the Gain of Function
research on bat coronaviruses that was being carried out in Wuhan in the second half of
2019.
●The 440-word assessment of the lab-accident pathway is supplemented by Annex D7 of
the report, which labels the lab-pathway as a ‘conspiracy theory’ five times while
containing disputed, incorrect, imprecise, and contradictory assertions (as detailed in
the supplement below).
●The final process utilized by the joint study team for assessing the likelihood of the lab
pathway – essentially a show of hands by the joint study team members based on an
extremely superficial review – failed to reach some most basic standards of credible
analysis and assessment. Further, it is at best unclear whether the Chinese joint study
team members had the leeway to express their fair evaluation of all hypotheses in the
presence of Chinese government minders.
2/9
Against these significant limitations and procedural failures that call the conclusions of the
China-WHO joint study report into question, we fully support the March 30, 2021 statement by
WHO Director-General Dr. Tedros Adhanom Ghebreyesus that all origin hypotheses must still be
examined, including the possibility of a lab-related incident, that China must be more forthright
in sharing essential data and biological samples, and that WHO is prepared to send additional
missions and experts to China in order to thoroughly examine all origin hypotheses. We
welcome this courageous defense of the WHO's integrity and recognize the organization’s
potential to lead a comprehensive investigation into pandemic origins, if given the mandate and
necessary support.
We further welcome the March 30, 2021 Joint Statement on the WHO-convened COVID-19
Origins Study by 14 countries underscoring the need for “a transparent and independent
analysis and evaluation, free from interference and undue influence” and voicing their shared
concern that the joint study “lacked access to complete, original data and samples.” We also
recognize the European Union Statement on the WHO-led COVID-19 Origins Study underlining
that the identification of the source of the SARS-CoV-2 virus will “require full and transparent
cooperation by all WHO Member States and a collaborative effort by scientists from various
disciplines.”
- Next steps -
The principles articulated by the WHO Director General and the two joint statements
mentioned above will require a renewed commitment by WHO and all Member States to a full
and unrestricted forensic and scientific investigation based on access, transparency and
timeliness. This essential goal must be realized in at least one of three possible concrete steps
forward.
1. Revise existing Terms of Reference
Given the extreme limitations of the present joint study, and in line with Dr. Tedros Adhanom
Ghebreyesus’s statement, we do not believe a comprehensive study of the origins of
SARS-CoV-2 has yet been undertaken. Accordingly, the most logical next step would be for the
existing Terms of Reference between the WHO and China for such search to be revised to make
such an examination possible. These revised terms should:
●Replace the veto power by any government over the composition of the international
experts team with a provision requiring final decisions regarding the make-up of the
international expert group to be made by the WHO Executive Board;
3/9
●Ensure the incorporation of a wider skill-set in the international experts team, including
biosafety and biosecurity experts, biodata analysts and experienced forensic
investigators;
●Guarantee a transparent selection of the experts team, backed by a more robust process
for dealing with possible conflicts of interest. Such a process should prevent any conflict
of interest involving prior professional association with laboratories and institutions
relevant to the investigation;
●Provide an official mandate allowing international experts to request full or significant
access to all sites, records, and samples of interest, and to interview relevant people
without the presence of government authorities and with the assistance of translators
provided by the WHO; and
●Make the revised Terms of Reference public immediately after negotiation so as to be
available for review by the international community and scientists.
2. Pass new World Health Assembly resolution
If these revisions cannot be agreed upon and implemented in the very near term, a second
option would be for interested governments to propose a new resolution at the May 2021
World Health Assembly. In addition to incorporating the points above, this new resolution
should:
●Call for an unrestricted international forensic and scientific investigation into the origins
of the pandemic, fully examining all COVID-19 origin hypotheses, with full access to all
records, samples, and personnel relevant to the investigation irrespective of location;
●Call for the timely and comprehensive sharing of raw data relevant to the emergence of
COVID-19 within the framework of Open Science and the FAIR principles;
●Call for improved national and international regulatory oversight of laboratories doing
high risk virology research, with specific emphasis on “gain of function research of
concern” (GOFROC); and
●Empower the World Health Organization to negotiate new Terms of Reference for this
full investigation based on the principles articulated above.
3. Establish parallel international investigation
If it should prove impossible for the Terms of Reference to be quickly revised or for a new and
sufficient World Health Assembly resolution to be passed in the coming session, the best
4/9
remaining alternative would be for governments seeking a full and credible examination into
the origins of the pandemic to come together to develop a new and independent process, with
China’s cooperation if possible but without it if not. Such a process would:
●Outline what a full and unrestricted investigation of all origins hypotheses would entail;
●Draw on the combined knowledge of government agencies and global experts to
examine all origin hypotheses to the full extent possible;
●Pool knowledge and intelligence of cooperating governments in a collaborative effort to
probe essential questions;
●Establish a secure whistleblower system allowing scientists and others in China and
other countries to share relevant information without fear of retribution; and
●Hold transparent public hearings designed to examine all hypotheses in the most
data-driven and responsible manner possible.
Calling for a full investigation into the origins of the pandemic by the best available means is not
intended to point fingers at any one country. Its purpose is to leave no stone unturned in
seeking to understand how this catastrophe began so we can prioritize efforts to address our
greatest shortcomings for the benefit of all people and all nations.

Supplement:
Some issues regarding Annex D7 (entitled ‘Wuhan Institute of Virology’) of the
‘WHO-convened Global Study of Origins of SARS-CoV-2: China part’
●Incorrect Statement: In Annex D7 Prof. Shi Zhengli states that the ‘miners had been to the
cave 2 - 3 times’ in relation to the Mojiang mine deaths in 2012. Actually the miners
developed symptoms after working 8 to 14 days in the mine for around 7 hours a day.
●Disputed Statement: In Annex D7 the ‘WIV experts’ are cited as saying that the Mojiang
miners’ deaths were ‘more likely explained by fungal infections’. The fungal infection
diagnosis is however in contradiction with the diagnostic of Prof. Zhong Nanshan, the
foremost Chinese SARS expert at the time, who diagnosed a most likely primary infection
from a SARS-like coronavirus, with a possible secondary fungal infection in some cases
(pulmonary aspergillosis). Further, the diagnosis of the ‘WIV experts’ also contradicts the
positive bat SARS coronavirus antibody tests (IgM and/or IgG) obtained for 4 of the 6
miners (these four tests were carried out at the WIV itself and described in this PhD
thesis).
●Incorrect Statement: Annex D7 wrongly describes the deleted database as an ‘Excel
spreadsheet that had been on the website for 10 years’ when actually it is a 61.5MB
MySQL database that had been released only a few years ago. This database represents
only one of multiple WIV databases that have been taken offline.
●Contradictory Statement: Annex D7 states that the database was taken offline after being
attacked by hackers. On another occasion Prof. Shi Zhengli explicitly stated that the
database was attacked by hackers during the pandemic and then taken offline. This is in
contradiction with the fact that the database was taken offline on September 12, 2019,
before the official start of the pandemic.
●Incorrect Statement: In Annex D7 Prof. Shi Zhengli is quoted as saying that ‘all fieldwork is
done with full PPE’. This is in contradiction with statements, photographic and video
records, showing limited PPE use by WIV personnel during field work. This was
additionally confirmed by Shi Zhengli herself in a presentation (starting from 16:30) she
gave in June 2018 (see transcript and translation)‘Although bats carry many viruses, the
chance of directly infecting humans is very small. Higher-level protection measures will be
taken when we know that bats in a certain location carry viruses that may be transmitted
to humans, and in most cases only ordinary protection will be taken.’
7/9
●Imprecise/Incorrect Statement: Annex D7 does not specify the number of people tested
for antibodies (IgG) within the Wuhan Institute of Virology and other labs in Wuhan
working on BatCoV. From the results (all negative) we can only infer that a small fraction of
the 590 WIV staff and students were actually tested. Indeed with the reported prevailing
background antibodies (IgG) positive rate of around 4% in urban Wuhan around April
2020, the probability of no positive antibodies test (IgG+) amongst any reasonable number
of potentially directly exposed staff and students becomes quickly extremely small, and is
effectively null for the full population of 590. A proper review of tests should instead
encompass all staff (including maintenance staff), all students and all construction and
temporary workers on site at the WIV, WIBP and at the other Wuhan P3 labs of interest,
plus all sample collection staff (some of which may not work at labs).
●Imprecise/Incorrect Statement: Annex D7 states that ‘all samples are stored, but not all
have been examined yet’, so there is not certitude that the WIV never collected or handled
SARS-CoV-2 samples since it may still be in a non-examined sample.
●Incorrect Statement: Annex D7 states that "The only SARS-CoV-2-like virus found by this
group is RaTG13", but 8 other SARS-CoV-2 most related viruses (the 7896 clade) can be
seen in slides shown by Dr. Shi Zheng Li in webinars.
●Imprecise/Contradictory Statement: Annex D7 states that “none of [the viruses from the
mine] has higher similarity to SARS-CoV-2 than the RaTG13 has”, but it is actually not
possible to make such an assertion when the 7896 clade viruses are also very similar to
SARS-CoV-2 based on their RdRp, but have still not been fully published more than a year
after the start of the pandemic (only the short RdRp sections have been published).
Moreover on other occasions the existence of a 100 or so related viruses (28:20) has been
mentioned.
●Imprecise Statement: Annex D7 states that “None [virus from the mine] could be isolated”.
It is not clear whether this refers generally to viruses found in the Mojiang mine, or strictly
to viruses similar to SARS-CoV-2. In any case, Dr. Shi herself has previously reported that
some bat adenoviruses had been isolated from samples ‘collected in Mojiang’, and the
WIV has also previously successfully isolated SARS-like viruses from Yunnan sites. Hence
the statement may not preclude the possibility that some similar coronaviruses may also
have been successfully isolated from Mojiang or elsewhere. We further note that the WIV
uses a very specific naming order for live viruses isolated in their laboratory according to
which there should be a WIV6 (not WIV06) isolate and a WIV15 one, which however are
not mentioned anywhere in the literature.
8/9
●Imprecise/Contradictory Statement: In Annex D7 Yuan Zhiming (the director of the WIV
P4 lab) refutes categorically any possibility of a lab-leak. Dr. Yuan Zhiming had
nevertheless repeatedly denounced structural issues with many labs in China before the
pandemic. As recently as October 2019, he wrote that:
○“Due to different investment sources, affiliations, and management systems, the
implementation of these laboratories faces difficulties converging objectives and
cooperation workflows. This scenario puts laboratory biosafety at risk since the
implementation efficiency and timely operations are relatively compromised.”
○“several high-level BSLs have insufficient operational funds for routine yet vital
processes. Due to the limited resources, some BSL-3 laboratories run on
extremely minimal operational costs or in some cases none at all.”
○“Currently, most laboratories lack specialized biosafety managers and engineers.
In such facilities, some of the skilled staff is composed by part-time researchers.
This makes it difficult to identify and mitigate potential safety hazards in facility
and equipment operation early enough.”
●Imprecise Statement: The few visits detailed in the Annexes (mostly D7) only cover
some the institutions in Wuhan with P2 and P3 labs that were known to be involved in
BatCoV research. A proper investigation should first clearly identify and then cover all
the labs in Wuhan that were actively working on BatCoVs in 2019 without exception, and
also the WIBP (next door to the WIV) which may have been involved in a BatCoV vaccine
development program (30:20).
●Imprecise Statement: Annex D7 provides neither the nature nor the details of research
involving bat coronaviruses in Wuhan laboratories in 2019 - including but not limited to
possible BatCoV vaccine development programs, pathogenicity studies involving animal
experiments, usage of passaging, Gain-Of-Function and genetic manipulation techniques
(29:50) - which should be one of the very first steps towards rationally identifying some
of the main risk factors in a lab-related accident scenario.
