On 27 December 2019, almost complete genetic sequencing of the previous sample have been finished and shared to Institute of Pathogen Biology, Chinese Academy of Medical Sciences & Peking Union Medical College (CAMS&PUMC).^[19] <>

29 December
According to a CCDC publication on 31 January 2020, the facts leading up to the identification of the 2019-nCoV were as follows, “On 29 December 2019, a hospital in Wuhan admitted four individuals with pneumonia and recognized that all four had worked in the Huanan Seafood Wholesale Market, which sells live poultry, aquatic products, and several kinds of wild animals to the public. The hospital reported this occurrence to the CCDC, which led Wuhan CCDC staff to initiate a field investigation with a retrospective search for pneumonia patients potentially linked to the market. The investigators found additional patients linked to the market, and on 30 December, health authorities from Hubei Province reported this cluster to CCDC. The following day, CCDC sent experts to Wuhan to support the investigation and control effort. Samples from these patients were obtained for laboratory analyses.”^[22] <>

30 December
On 30 December 2019, genetic sequencing report of the pathogen of a patient indicated inaccurately the discovery of Severe acute respiratory syndrome coronavirus <> (SARS coronavirus) in the test result.^[19] <> After receiving the test result, multiple doctors in Wuhan shared the information via internet, including Dr. Li Wenliang <>, an ophthalmologist at Wuhan Central Hospital <>, who posted a warning to alumni from his medical school class via a WeChat <> online forum that a cluster of seven patients treating within the ophthalmology department had been unsuccessfully treated for symptoms of viral pneumonia and diagnosed with SARS <>.^[23] <> ^[24] <> ^[19] <> Because these patients did not respond to traditional treatments, they were quarantined in an ER department of the Wuhan Central Hospital.^[25] <> In the WeChat forum, Li posted that this cluster of patients appeared to be infected by SARS. Dr. Li posted a snippet of an RNA analysis finding “SARS coronavirus” and extensive bacteria colonies in a patient’s airways according to a chat transcript that he and other chat members later shared online. Dr. Li contracted this coronavirus from a patient he treated, was hospitalized on 12 January 2020 and died on 6 February 2020.^[26] <> Due to public outcry directed to the CCP outlets retracted original reports, while international news agents corrected reports published on the 6th stating the death on 7th. The official date of death was later announced as 7 February 2020.^[27] <> Dr. Li is widely known for the statement he gave before his death exemplifying how the Chinese government botched the containment of the novel coronavirus, stating “There should be more than one voice in a healthy society.”^[23] <>
The Chinese National Health Commission announced later that evening that 8 doctors engaging in this WeChat forum had been arrested by Wuhan Police and charged with “illegal acts of fabricating, spreading rumors and disrupting social order.”^[28] <>

How can we get infected?”^[32] <>
“Chinese state television reported that a team of experts from the National Health Commission had arrived in Wuhan on 31 December 2019 to lead the investigation, while the People’s Daily said the exact cause remained unclear and it would be premature to speculate.”^[31] <> ^[32] <> ^[41] <> Chinese state broadcaster CCTV reported that a team of senior health experts had been dispatched to the city of Wuhan and were reported to be “conducting relevant inspection and verification work.”^[33] <>

On 3 January 2020, Dr. Li Wenliang, the Wuhan ophthalmologist who had been arrested for spreading false “rumors” on WeChat, was summoned to the Wuhan Public Security Bureau where he was told to sign an official confession and admonition letter promising to cease spreading false “rumors” regarding the coronavirus. In the letter, he was accused of “making false comments” that had “severely disturbed the social order”. The letter stated, “We solemnly warn you: If you keep being stubborn, with such impertinence, and continue this illegal activity, you will be brought to justice—is that understood?” Dr. Li signed the confession writing: “Yes, I understand.”^[24] <> Li would later be supported e.g. in a blog run by China’s Supreme People’s Court on 28 January 2020.^[46] <> On 7 February 2020, Chinese state-sponsored news reported that Dr. Li had died from complications arising from his infection to the Wuhan coronavirus only to later delete the post and report Dr. Li as being in critical condition.^[47] <> He was subsequently confirmed the same day as having regrettably indeed deceased.^[48] <> Dr. Li is now being heralded as a whistleblower who exposed the Chinese government’s early efforts to cover up the seriousness of the coronavirus pandemic which resulted in its rapid spread across China and the world.^[23] <>

Chinese officials were criticized for failing to disclose any information about the “mysterious virus” that machine translations of official reports suggested may be caused by a new coronavirus.^[45] <>
The WHO waited for China to release information about the “mysterious new pneumonia virus”.^[53] <> The United Nations agency activated its incident-management system at the country, regional and global level and was standing ready to launch a broader response if it was needed. The WHO’s regional office in Manila said in Twitter posts Saturday.: “#China has reported to WHO regarding a cluster of pneumonia cases in Wuhan, Hubei Province.The Govt has also met with our country office, and updated @WHO on the situation.

Dr. Gabriel Leung, Dean of the University of Hong Kong medical school and one of the foremost world experts on SARS and viruses, gave a three-hour presentation published on YouTube wherein he made nowcasts and forecasts of the coronavirus.
