Two leaks from Chinese labs in fall 2019 are the most likely sources of the coronavirus’ spread among humans, a Senate report concluded after an 18-month investigation into how the COVID-19 pandemic began — a thorny question that has stumped two administrations and fueled rancor between Washington and Beijing.
Sen. Roger Marshall, Kansas Republican, circulated the report. The weight of evidence shows that the pandemic was caused by unintentional lab incidents in Wuhan, China, as far back as October 2019. The virus swept through the central Chinese city before emerging as a global concern by January 2020.
“Based on the publicly available evidence, it appears Wuhan is the only location where SARS-CoV-2 spilled over into humans,” said the report, using the formal name for the virus that causes COVID-19 disease. “The low genetic diversity of earliest SARS-CoV-2 samples suggests that [the] COVID-19 pandemic is most likely the result of one or possibly two successful introductions of SARS-CoV-2. Additionally, these estimates indicate that the initial introduction may have occurred on or about November 18 and a second within weeks of the first.”
Dr. Robert Kadlec, who played a crucial role in Operation Warp Speed to develop a COVID-19 vaccine during the Trump administration, prepared the report.
The 300-page document undercuts Beijing’s official position that the outbreak began in December 2019 and says the Chinese Communist Party started to develop a vaccine after the first leak, which went unnoticed outside China, and before the global surge of COVID-19 cases in early 2020.
Dr. Zhou Yusen, a Chinese military scientist, filed a patent for a COVID-19 vaccine on Feb. 24, 2020, that would have required weeks of work to sequence the new virus, according to the report.

The Marshall report adds momentum to the lab leak theory, which the political left initially discredited as disinformation. The theory has been bolstered by evidence that some workers at the Wuhan lab were hospitalized for flulike illness before the coronavirus spread across the city.
Dr. Robert Redfield, a former director of the Centers for Disease Control and Prevention, and others said the virus had properties not found in other coronaviruses, adding to the likelihood that it was engineered.
John L. Ratcliffe, who served as director of national intelligence during the first year of the pandemic, said Tuesday that the intelligence community should be more aggressive with its conclusion.
He told Congress that the bank of evidence indicating a spillover from nature is “nearly empty and tenuous.” For instance, no one has been able to confirm a reservoir species or animal through which the virus jumped to humans.
“On the other side of the ledger, it’s overwhelming when you look at China’s actions and the circumstances surrounding what was going on from a biosafety standpoint at Wuhan, the massive number of coronaviruses, the massive numbers of bats carrying coronaviruses that were brought into Wuhan,” Mr. Ratcliffe told the House Select Committee on the Coronavirus Pandemic. “All of that weighs heavily into making assessments at some confidence level that a lab leak was the origin for this pandemic.”
The origin of the pandemic was initially pinpointed to a wet market in Wuhan, where the virus was first detected. It quickly spread to Italy, South Korea, Iran and the rest of the world. COVID-19 has killed nearly 7 million people worldwide.
Democrats and Republicans agree that it’s essential to find the source of the virus that causes COVID-19. Still, the search has been hindered by the communist government in Beijing and has become a political football in the U.S.
Mr. Ratcliffe said efforts to investigate the origin of the virus were hampered by claims on news media and social media platforms that dismissed speculation of a lab leak as a conspiracy theory.
Dr. Anthony Fauci of the National Institutes of Health tended to emphasize the natural spillover theory. Now retired, the doctor says he is open to investigations into the true origins of the virus.
People sitting behind the witnesses at Tuesday’s hearing wore T-shirts reading “Jail Fauci.”
Democrats on the House panel said they are open to the origins inquiry but don’t want lawmakers to vilify top health officials while ignoring President Trump’s comments in early 2020.
Rep. Jared Moskowitz, Florida Democrat, read a series of tweets in which Mr. Trump praised Chinese President Xi Jinping’s early handling of the COVID-19 outbreak and predicted that the pathogen would disappear.
Mr. Moskowitz said the subcommittee should investigate whether government professionals failed to share information with Mr. Trump “because they didn’t trust the president, because every day he was going out saying this stuff.”
Mr. Ratcliffe said the CIA could make firmer declarations about a lab leak but is reluctant to wade into the issue.
“Such an assessment would have enormous geopolitical implications that the Biden administration seemingly does not want to face head-on,” Mr. Ratcliffe testified.
The White House says President Biden is serious about finding the origin of the coronavirus and points to various intelligence reviews that have produced conflicting results.
Mr. Biden recently signed legislation that requires the Office of the Director of National Intelligence to declassify information and report to Congress within 90 days about possible ties between the virus and the lab in Wuhan.
“There is no doubt that the administration has far more information than has been released publicly,” David Feith, a former deputy assistant secretary of state for East Asian and Pacific affairs, told the select subcommittee.
Mr. Feith said the intelligence community should disclose the additional information it probably has about six Wuhan researchers who were sick in late 2019.
Those lab workers remain the “best lead into who or what was patient zero,” he said. “No animal anywhere has been identified as a comparably likely source of the outbreak.”
Another witness said the committee should know that the U.S. might never get firm answers.
“Absent greater cooperation and transparency from China, which seems highly unlikely, we may never resolve this issue with certainty,” said Mark M. Lowenthal, a former State Department official and former assistant director of central intelligence for analysis and production.
China has consistently denied that the virus leaked from a lab and has stood by early conclusions that the virus transferred from animals to humans.
Mr. Marshall pointed to the Wuhan Institute of Virology’s deletion of its online database of virus samples on Sept. 12, 2019. He said it raises suspicion that Chinese officials knew about the virus long before they sounded the global alarm.
The Energy Department concluded with low confidence this year that the COVID-19 pandemic resulted from a laboratory leak in China.
Earlier, the FBI concluded with moderate confidence that a lab leak was responsible for the virus’ spread. Intelligence agencies have determined with low confidence that the virus emerged from natural channels, according to a review that Mr. Biden ordered in 2021.
Dr. Redfield and other witnesses told the House coronavirus panel in March that the virus had a distinct feature, or furin cleavage site, that let the pathogen infect humans easily and was unusual for known coronaviruses, leading them to suspect it was engineered in a lab.
On Tuesday, Mr. Ratcliffe pointed to China’s efforts to destroy lab samples at a Wuhan lab known for risky research and Beijing’s efforts to coerce witnesses and strong-arm global health investigators.
“My informed assessment, as a person with as much or more access than anyone to our government’s intelligence during the initial year of the virus outbreak and pandemic onset, has been and continues to be that a lab leak is the only explanation credibly supported by our intelligence, by science and by common sense,” he said.
