“A Chinese virologist has claimed she fled Hong Kong to expose the truth about a Beijing cover-up over the initial outbreak of COVID-19. Li-Meng Yan, a scientist at the Hong Kong School of Public Health, feared she would be killed for speaking out in China and chose to escape to the United States, where she is hiding at an undisclosed location. According to the researcher, the Chinese Communist Party and senior university staff suppressed evidence that coronavirus could be transmitted between humans as early as last December. Dr Yan, who grew up in mainland China, said she was among the first scientists asked to investigate a small number of cases in Wuhan. She claimed the Chinese government refused to let overseas experts, including those from Hong Kong, conduct research in China. On December 31 she turned to her contacts on the mainland for more information, including an expert at the Centre for Disease Control and Prevention. One said that there were cases of “family clusters”, indicating human-to-human transmission, she claimed. Dr Yan said when she reported to her boss, Leo Poon, an Oxford-educated supervisor at the university, he ignored the information. The Hong Kong centre is used by the World Health Organisation as a reference laboratory and specialises in viruses. On January 9, it released a statement supporting Chinese claims that the virus “does not transmit readily among people”. A few weeks later Wuhan was quarantined. One study by Chinese and British experts found that had the lockdown begun at the start of the year, the number of cases could have been cut by 95 per cent, according to the Daily Mail. In a statement, the Hong Kong centre said Dr Yan’s reported comments had “no scientific basis but resembles hearsay”.
“On the whole, though, Yan doesn't really tell us anything we didn't already know. It's been clear that China delayed telling the public about the Wuhan outbreak. She doesn't indicate having any information about the virus' origin, and she certainly does not provide any useful recommendations for how to protect ourselves. In fact, she parrots the recommendations of most governments — staying 6 feet apart, using alcohol-based disinfectants and wearing surgical masks. Aside from disinfectants, which may be useful for killing viruses on hands and surfaces, social distancing and mask wearing have no basis in actual science. You can learn more about these two interventions in "Why Social Distancing Should Not Be the New Normal" and "Conclusive Proof — Masks Do Not Inhibit Viral Spread." Of course, the Chinese have been known to wear face masks in public for some time, but they've primarily been worn to protect the wearer against air pollution — not infectious disease. Just because masks prevent inhalation of dangerous air pollution does not mean they work against viruses. Based on current data, Yan also seems to exaggerate the dangers of the virus, seeing how the COVID-19 mortality rate is now down to a fraction of a percent and a vast majority — about 90% — of those infected remain completely asymptomatic. All of that said, she's certainly correct when saying that the CCP's attempts to keep details of the Wuhan outbreak from the public allowed the virus to spread, not only through China but also across the world.”
And what is being done about this? Nothing; the world is simply too scared of China to lift a finger.
