Leaked documents reveal China’s mishandling of the early stages of Covid-19

London — A group of frontline medical workers, likely exhausted, stand huddled together on a video-conference call as China’s most powerful man raises his hand in greeting. It is February 10 in Beijing and President Xi Jinping, who for weeks has been absent from public view, is addressing hospital staff in the city of Wuhan as they battle to contain the spread of a still officially unnamed novel coronavirus.

From a secure room about 1,200 kilometers (745 miles) from the epicenter, Xi expressed his condolences to those who have died in the outbreak. He urged greater public communication, as around the world concerns mounted about the potential threat posed by the new disease.

That same day, Chinese authorities reported 2,478 new confirmed cases — raising the total global number to more than 40,000, with fewer than 400 cases occurring outside of mainland China. Yet CNN can now reveal how official documents circulated internally show that this was only part of the picture.

CNN’s key findings

Chinese officials gave the world more optimistic data than they had access to internally
China’s system took on average 23 days to diagnose confirmed patients, and testing failures meant most received negative results until January 10
A history of underfunding, understaffing, poor morale and bureaucratic models of governance hampered China’s early warning system, internal audits found
A large and previously undisclosed outbreak of influenza happened in early December in Hubei province.

In a report marked “internal document, please keep confidential,” local health authorities in the province of Hubei, where the virus was first detected, list a total of 5,918 newly detected cases on February 10, more than double the official public number of confirmed cases, breaking down the total into a variety of subcategories. This larger figure was never fully revealed at that time, as China’s accounting system seemed, in the tumult of the early weeks of the pandemic, to downplay the severity of the outbreak.

The previously undisclosed figure is among a string of revelations contained within 117 pages of leaked documents from the Hubei Provincial Center for Disease Control and Prevention, shared with and verified by CNN.

Taken together, the documents amount to the most significant leak from inside China since the beginning of the pandemic and provide the first clear window into what local authorities knew internally and when.

The Chinese government has steadfastly rejected accusations made by the United States and other Western governments that it deliberately concealed information relating to the virus, maintaining that it has been upfront since the beginning of the outbreak. However, though the documents provide no evidence of a deliberate attempt to obfuscate findings, they do reveal numerous inconsistencies in what authorities believed to be happening and what was revealed to the public.

The documents, which cover an incomplete period between October 2019 and April this year, reveal what appears to be an inflexible health care system constrained by top-down bureaucracy and rigid procedures that were ill-equipped to deal with the emerging crisis. At several critical moments in the early phase of the pandemic, the documents show evidence of clear missteps and point to a pattern of institutional failings.

One of the more striking data points concerns the slowness with which local Covid-19 patients were diagnosed. Even as authorities in Hubei presented their handling of the initial outbreak to the public as efficient and transparent, the documents show that local health officials were reliant on flawed testing and reporting mechanisms. A report in the documents from early March says the average time between the onset of symptoms to confirmed diagnosis was 23.3 days, which experts have told CNN would have significantly hampered steps to both monitor and combat the disease.

China has staunchly defended its handling of the outbreak. At a news conference on June 7, China’s State Council released a White Paper saying the Chinese government had always published information related to the epidemic in a “timely, open and transparent fashion.”

“While making an all-out effort to contain the virus, China has also acted with a keen sense of responsibility to humanity, its people, posterity, and the international community. It has provided information on Covid-19 in a thoroughly professional and efficient way. It has released authoritative and detailed information as early as possible on a regular basis, thus effectively responding to public concern and building public consensus,” says the White Paper.

CNN has reached out to China’s Ministry of Foreign Affairs, and National Health Commission, as well as Hubei’s Health Commission, which oversees the provincial CDC, for comment on the findings disclosed in the documents, but received no response.

Health experts said the documents laid bare why what China knew in the early months mattered.

Medical personnel work in the intensive care unit at a Wuhan hospital on February 24.

“It was clear they did make mistakes — and not just mistakes that happen when you’re dealing with a novel virus — also bureaucratic and politically-motivated errors in how they handled it,” said Yanzhong Huang, a senior fellow for global health at the Council on Foreign Relations, who has written extensively on public health in China. “These had global consequences. You can never guarantee 100% transparency. It’s not just about any intentional cover-up, you are also constrained with by technology and other issues with a novel virus. But even if they had been 100% transparent, that would not stop the Trump administration downplaying the seriousness of it. It would probably not have stopped this developing into a pandemic.”

Tuesday, December 1, marks one year since the first known patient showed symptoms of the disease in the Hubei provincial capital of Wuhan, according to a key study in the Lancet medical journal.

At the same time that the virus is believed to have first emerged, the documents show another health crisis was unfolding: Hubei was dealing with a significant influenza outbreak. It caused cases to rise to 20 times the level recorded the previous year, the documents show, placing enormous levels of additional stress on an already stretched health care system.

The influenza “epidemic,” as officials noted in the document, was not only present in Wuhan in December, but was greatest in the neighboring cities of Yichang and Xianning. It remains unclear what impact or connection the influenza spike had on the Covid-19 outbreak. And while there is no suggestion in the documents the two parallel crises are linked, information regarding the magnitude of Hubei’s influenza spike has still yet to be made public.

The leaked revelations come as pressure builds from the US and the European Union on China to fully cooperate with a World Health Organization inquiry into the origins of the virus that has since spread to every corner of the globe, infecting more than 60 million people and killing 1.46 million.

But, so far, access for international experts to hospital medial records and raw data in Hubei has been limited, with the WHO saying last week they had “reassurances from our Chinese government colleagues that a trip to the field” would be granted as part of their investigation.

The files were presented to CNN by a whistleblower who requested anonymity. They said they worked inside the Chinese healthcare system, and were a patriot motivated to expose a truth that had been censored, and honor colleagues who had also spoken out. It is unclear how the documents were obtained or why specific papers were selected.

The documents have been verified by six independent experts who examined the veracity of their content on behalf of CNN. One expert with close ties to China reported seeing some of the reports during confidential research earlier this year. A European security official with knowledge of Chinese internal documents and procedures also confirmed to CNN that the files were genuine.

Metadata from the files seen by CNN contains the names of serving CDC officials as modifiers and authors. The metadata creation dates align with the content of the documents. Digital forensic analysis was also performed to test their computer code against their purported origins.

Sarah Morris, from the Digital Forensics Unit at Britain’s Cranfield University, said there was no evidence the data had been tampered with or was misleading. She added the older files looked like they had been used repeatedly over a long period of time. “It’s almost like a mini file system,” she said. “So, it’s got lots of room for deleted stuff, for old things. That’s a really good sign [of authenticity].”

World got more optimistic data than reality

The documents show a wide-range of data on two specific days, February 10 and March 7, that is often at odds with what officials said publicly at the time. This discrepancy was likely due to a combination of a highly dysfunctional reporting system and a recurrent instinct to suppress bad news, said analysts. These documents show the full extent of what officials knew, but chose not to spell out to the public.

On February 10, when China reported 2,478 new confirmed cases nationwide, the documents show Hubei actually circulated a different total of 5,918 newly reported cases. The internal number is divided into subcategories, providing an insight into the full scope of Hubei’s diagnosis methodology at the time.

“Confirmed cases” number 2,345, “clinically diagnosed cases” 1,772, and “suspected cases” 1,796.
