From 10 February 2020 onwards, the data includes the cases in Hubei that were not tested for the virus but clinically diagnosed based on medical imaging showing signs of pneumonia.^[1] The lab-tested data was also separately available for 10–15 February 2020.^[2] Data from 16 February 2020 onwards did not include a separate number of lab-tested cases. From 19 February 2020 onwards, only new lab-tested cases were counted towards the total (but clinically diagnosed cases counted earlier were not discarded).^[3] On 17 April 2020, following the Wuhan government's issuance of a report on accounting for COVID-19 deaths that occurred at home that went previously unreported, as well as the subtraction of deaths that were previously double-counted by different hospitals, the NHC revised their cumulative totals dating to 16 April, adding 325 cumulative cases and 1,290 deaths.^[4] Data sourced from NHC daily reports. (In another link before January 25, on Wuhan MHC website before January 10) ^ The 02-10 and 02-11 clinically diagnosed data has been based on appendix in the 02-11 Hubei WJW data, with 02-10's data obtained from deducting the number of new C.D. cases on that day from the total. ^ The 02-12 data has been corrected based on the 02-13 NHC subtraction data and corresponding 02-13 Hubei data. ^ The 02-18 number of tested cases is calculated based on the 02-19 subtraction data. ^ Data from 02-19 excludes clinical diagnoses, so the calculation is made provisionally for ease of understanding the progression of the situation.

This article documents the chronology and epidemiology of the Novel coronavirus^[5] responsible for the 2019–20 outbreak in Wuhan, China, and may not include all contemporary major responses and measures. Furthermore, some developments may become known or fully understood only in retrospect.

Notes: ^ The sum of the numbers may differ with the total mainland number, because not all province-level divisions report by the interval of 00:00-24:00. ^ When a cell contains two rows of numbers, the upper number is the number of cases confirmed with nucleic acid testing, and the lower number is that of clinical diagnosis per medical imaging features, as specified in the fifth pilot version of the national diagnostic guideline. Clinical diagnosis was used in Hubei exclusively during 12-18 Feb. This table keeps the two distinct for consistency; the sum of the two categories yields the reported total of Hubei. ^ On occasions, a number does not match the source for the day because cases were subtracted after verification the next day. An example is the 12 Feb data for Hubei (clinical), from which 1,043 cases were subtracted the next day. Hubei also subtracted 195 cases on 23 Feb for double counting. ^ For 15 Feb, Hubei did not release separate numbers for its city level divisions. ^ For 19 Feb, three provinces (Jiangxi, Henan, Yunnan) made corrections to their prior case counts by recording a reduction of 1 case each. ^ Since 19 Feb, clinical diagnoses have been excluded from the data as the sixth pilot version of the NHC guidelines removed the category. Case information: ^ Includes 27 in Shilifeng Prison.^[88] ^ Includes 200 cases in Rencheng Prison.^[89] ^ Includes 220 in Wuhan Women's Prison and Shayang Hanjin Prison. ^ The patient travelled from Iran transiting at Moscow and arrived in Shanghai at 23:05 on 20 February.

Outbreak chronology

1–18 December 2019

In January 2020, a consortium of Chinese medical experts were charged with investigating the inception of what is now commonly known as the Wuhan Coronavirus. On 24 January 2020 their report was published in The Lancet.^[150] They noted from their review of local medical records that the first patient later to be diagnosed with the Wuhan Coronavirus first presented with symptoms on 8 December 2019. However, the consortium found an earlier case of a patient who first experienced symptoms on 1 December 2019, pointing to an even earlier origin.^[151] Apart from this early case, between December 8 and December 18, seven cases later diagnosed with Wuhan Coronavirus were documented, two of them were linked with the Huanan Seafood Wholesale Market of Wuhan, five were not.^[152]

30 December 2019

On 30 December 2019, Dr. Li Wenliang, an Opthomologist in Wuhan, China, posted a warning to doctors from his medical school class via a WeChat online forum that a cluster of seven patients treating within the opthomology department had been unsuccessfully treated for symptoms of viral pneumonia.^[153] Because these patients did not respond to traditional treatments, they were quarantined in an ER department of a local Wuhan hospital.^[154] In the WeChat forum, Li posted that this cluster of patients appeared to be infected by SARS. 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. The Chinese National Health Commission, announced that later that evening, 8 doctors engaging in this WeChat forum were arrested by Wuhan Police and charged with "llegal acts of fabricating, spreading rumors and disrupting social order..."^[155]^[156]

31 December 2019

On 31 December 2019, an "urgent notice on the treatment of pneumonia of unknown cause" was issued to the Wuhan Municipal Health Committee. The Wuhan Municipal Health Committee reported to the WHO that 27 people were diagnosed with pneumonia of unknown cause. (See Notifiable disease#Global.) Most were stallholders from the Huanan Seafood Wholesale Market, seven of whom were in critical condition. The Wuhan Municipal Health Commission also made a public announcement regarding the situation.^[74] Hong Kong, Macau and Taiwan immediately tightened their inbound screening processes as a result.^[157]^[158]

1 January

According to the Chinese state-sponsored Xinhua News, the Hunan Seafood Market was closed on 1 January 2020 for "renovations."^[154] However, in the consortium's report of 24 January 2020 they stated that the Hunan Seafood Market had been closed on 1 January 2020 for "cleaning and disinfection."^[157]

2 January

On 2 January, 41 admitted hospital patients in Wuhan, China were confirmed to have contracted (laboratory-confirmed) the 2019-nCoV (Wuhan Caronavirus). 27 (66%) patients had direct exposure to Huanan Seafood Wholesale Market.^[159]

3 January

On 3 January 2020, Dr. Li Wenliang, the Wuhan opthamologist who was 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."^[160] Li would later be vindicated in a ruling issued by China's Supreme People's Court on 28 January 2020.^[161]

5 January

Early investigations into the cause of the pneumonia ruled out seasonal flu, SARS, MERS and bird flu.^[162]^[163] The number of suspected cases reached 59 with seven in a critical condition. All were quarantined and local medical officials commenced monitoring of 163 of their contacts. At this time, there were no reported cases of human-to-human transmission or presentations in healthcare workers.^[164]^[165]

9 January

The WHO confirmed that a novel coronavirus had been isolated from one person who was hospitalised.^[166]^[167] On the same day, the European Centre for Disease Prevention and Control posted its first risk assessment.^[168] The WHO also reported that Chinese authorities had acted swiftly,^[166] identifying the novel coronavirus within weeks of the onset of the outbreak, with the total number of positively tested people being 41.^[169] The first death from the virus occurred in a 61-year-old man who was a regular customer at the market. He had several significant medical conditions, including chronic liver disease, and died from heart failure and pneumonia. The incident was reported in China by the health commission via Chinese state media on 11 January.^[170]^[171]^[172]^[173]

10 January

The gene sequencing data of the isolated 2019-nCoV, a virus from the same family as the SARS coronavirus, was posted on Virological.org by researchers from Fudan University, Shanghai. A further three sequences from the Chinese Center for Disease Control and Prevention, one from the Chinese Academy of Medical Sciences, and one from Jinyintan Hospital in Wuhan were posted to the Global Initiative on Sharing All Influenza Data (GISAID) portal.^[174]^[170]^[175]^[176] The same day, Public Health England issued its guidance.^[168]

On 10 January 2020, Dr. Li Wenliang, Chinese ophthalmologist and Coronavirus whistleblower started having symptoms of a dry cough. On 12 January 2020, Dr. Wenliang started having a fever. He was admitted to the hospital on 14 January 2020. His parents also contracted the Coronavirus (presumably from Dr. Wenliang) and were admitted to the hospital with him.

She had arrived in Bangkok on 8 January.^[181]

14 January

On 14 January, two of the 41 confirmed cases in Wuhan were reported to include a married couple, raising the possibility of human-to-human transmission.^[181]^[182]

15 January

A second death occurred in a 69-year-old man in China on 15 January.^[183]^[184] The WHO published a protocol on diagnostic testing for 2019-nCoV, developed by a virology team from Charité Hospital.^[183]

16 January

On 16 January, the WHO was alerted by Japan's Ministry of Health, Labour and Welfare that a 30-year-old male Chinese national had tested positive to 2019-nCoV during a hospital stay between 10 and 15 January. He had not visited the Huanan Seafood Wholesale Market, but possibly had close contact with an affected person in Wuhan.^[185]^[186]

17 January

On 17 January, Thailand's second confirmed case was reported in a 74-year-old woman who arrived in Bangkok on a flight from Wuhan.^[187]^[188] The number of laboratory-confirmed cases rose to 45 in China.^[189]

WHO Situation Report 7:^[293]

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 Wuhan Virus Pandemic. Using traditional scientific modeling techniques that predict the spread of viruses, Dr. Leung projected the true number of coronavirus infections was likely 10 time more than the official reported numbers.^[294]Dr. Leung estimated that there were between 44,000-100,000 infections in China as of 24 January 2020. He stated that draconian measures were needed to slow the progress of the virus but that these measures would have no effect in stopping the coronavirus pandemic. He projected that the number of infections would continue exponentially peaking out in late April or May 2020. Dr. Leung predicted that at the peak of the pandemic, there could be up to 100,000 new infections per day. Dr. Leung subsequently published an article in The Lancet nowcasting and forecasting the likely progression of the Wuhan Coronavirus taking into consideration numerous variables.^[295] Zhou Xianwang, the mayor of Wuhan, said on a Chinese state television talkshow that rules imposed by Beijing limited what he could disclose about the threat posed by the Wuhan Coronavirus as it unfolded, suggesting "the central government was partially responsible for a lack of transparency that has marred the response to the fast-expanding health crisis."^[296]

China's Supreme People's Court ruled that whistleblower, Li Wenjian, had not committed the crime of spreading "rumors" when on 30 December 2019 he posted to a WeChat forum for medical school alumni that seven patients under his care appeared to have contracted SARS. In their ruling, the Supreme People's Court stated, “If society had at the time believed those ‘rumors,’ and wore masks, used disinfectant and avoided going to the wildlife market as if there were a SARS outbreak, perhaps it would’ve meant we could better control the coronavirus today,” the court said. “Rumors end when there is openness.”^[319]^[320]
