Matt Ridley at The Critic reviews Dali Lang's new book Wuhan: How the COVID-19 Outbreak in China Spiralled Out of Control, which argues that the pandemic could probably have been prevented had the Wuhan authorities acted differently in the last days of 2019 and the first week of 2020.
The authorities, as well as punishing and silencing the whistle-blowers, took the line that this mysterious outbreak was the result of zoonosis – humans infected from an animal source – from the Wuhan seafood market. The market was closed down, while concerns that people with no connection to the market were getting infected were ignored.
The Wuhan Municipal Health Commission issued guidelines on how to diagnose the new disease. In addition to clinical symptoms, under the “inclusion-exclusion criteria”, a patient had to have had a link or proximity to the Huanan Seafood Market to be treated as having Covid.
As a result, cases with no link to the market were ignored. “They only transferred those [patients] with an exposure history to the Seafood Market, including those we had almost cured,” complained one doctor at the hospital designated for receiving Covid patients. “But they didn’t want any [patient] without a history of contact with [the] Seafood Market.”
After the market was closed the number of patients seemed to stabilise and fall, reassuring the authorities. But inside the hospitals of Wuhan, more and more people were presenting with symptoms and more and more doctors and nurses were falling ill, only for their cases to be deleted from the data by provincial bureaucrats in thrall to the seafood-market dogma.
This problem of “ascertainment bias” was also to fool western scientists for years as they continued to argue that because early cases were associated with, or lived near, the market, the virus must have started there. This was and is a circular argument.
The authorities, in other words, decided that the seafood market was the cause of the outbreak, and then dismissed data that didn't tie in with their theory.
Ridley – co-author of Viral: The Search for the Origin of Covid-19 – notes that Dali Yang confines his criticism to the local authorities, not Beijing, and barely touches on the issue of a lab-leak.
But the author, Dali Yang, is a professor at the University of Chicago and between 2010 and 2016, was the founding faculty director of the University of Chicago Center in Beijing. He is also a member of the National Committee on US-China Relations, and a member of the China committee of the Chicago Sister Cities International program. His ready access to Chinese sources must require at the very least some caution about saying things that go against Xi Jinping Thought. Hence, perhaps, the decision not even to discuss a laboratory leak, the ultimate no-no in Beijing.
