US intelligence report claims researchers at Wuhan lab fell ill, sought hospital care before Covid-19 disclosure

A US intelligence report found that several researchers at China’s Wuhan Institute of Virology fell ill in November 2019 and had to be hospitalized, a new detail about the severity of their symptoms that could fuel further debate about the origins of the coronavirus pandemic.

A State Department fact sheet released by the Trump administration in January said that the researchers had gotten sick in autumn 2019 but did not go as far as to say they had been hospitalized.

China reported to the World Health Organization that the first patient with Covid-like symptoms was recorded in Wuhan on December 8, 2019.




The intelligence community however still don’t know what the researchers were actually sick with, according to two people briefed on the intelligence.

“At the end of the day, there is still nothing definitive,” said one of the people who has seen the intelligence.

Director of National Intelligence Avril Haines told lawmakers during the Worldwide Threats Hearing last month that “the intelligence community does not know exactly where, when, or how Covid-19 virus was transmitted initially,” an assessment that has not changed, said two of the people briefed on the intelligence.



The current intelligence reinforces the belief that the virus most likely originated naturally, from animal-human contact, the sources said. But that does not preclude the possibility that the virus was the result of an accidental leak from the Wuhan Institute, where coronavirus research was being conducted on bats.

World Health Organization conducted an investigation into the origins of the pandemic and concluded in a report that the risk of an accident was “extremely low.”

The report said there was “no reporting of Covid-19 compatible respiratory illness during the weeks/months prior to December 2019, and no serological evidence of infection in workers through SARS-CoV-2-specific serology-screening.”

But the WHO probe was swiftly criticized by the US, UK, and other governments over its limited access to “complete, original data and samples.”

The organization was also accused of being overly deferential to China throughout the course of the study, which was co-authored by 17 Chinese scientists.

Current and former intelligence officials say that the idea that the virus was accidentally unleashed from the lab at Wuhan is reasonable, although they caution that there is no high-confidence assessment of that possibility.

In the final days of the Trump administration, former Secretary of State Mike Pompeo leaned into the possibility that the virus leaked from the Wuhan Institute of Virology, or WIV.

Despite the intelligence being inconclusive, Pompeo put out a fact sheet that said the US had evidence researchers at the WIV had been sick in the fall of 2019 with Covid-like symptoms and that the lab, where coronavirus had been studied in bats, had a history of military research.




One of the challenges in developing any certainty is access to the lab itself. China delayed access to international investigators for months after the initial outbreak, virtually guaranteeing that the lab had been deep-cleaned before any forensic analysis could be done, and investigators were also not allowed to view original data logs that scientists say would be critical to understanding the virus’ origins.

One critical avenue to finding an answer would be to run genetic sequencing on the original samples that staff at the Wuhan lab were working on.
