The 2019–2020 COVID-19 outbreak in mainland China was the first

severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). China
was the first country to experience an outbreak of the disease, the first to impose drastic measures in response (including lockdowns and face mask mandates), and one of the first countries to bring the outbreak under control.

The outbreak was first manifested as a cluster of mysterious

SARS-CoV-2) was identified as the cause of the pneumonia by Chinese scientists.[3]

During the beginning of the pandemic, the Chinese government showed a pattern of secrecy and top-down control.[4] It censored discussions about the outbreak since the beginning of its spread, from as early as 1 January,[5][6] worked to censor and counter reporting and criticism about the crisis – which included the detention of several citizen journalists[7] – and portray the official response to the outbreak in a positive light,[8][9][10] and restricted and facilitated investigations probing the origins of COVID-19.[4][11] Several commentators suspected the Chinese government had deliberately under-reported the extent of infections and deaths.[12][13][14] However, some academic studies have found no evidence that China manipulates COVID-19 data.[15][16][17]

The

Public Health Emergency of International Concern.[25] A severe shortage of face masks and other protective gear[29] led several countries to send international aid, including medical supplies, to China.[30][31][32]

By late February, the pandemic had been brought under control in most Chinese provinces. On 25 February, the reported number of newly confirmed cases outside mainland China exceeded those reported from within for the first time; the WHO estimated that the measures taken in the country averted a significant number of cases.[33] By 6 March the reported number of new cases had dropped to fewer than 100 nationally per day, down from thousands per day at the height of the crisis. On 13 March, the reported number of newly imported cases passed that of domestically transmitted new cases for the first time.[34]

By the Summer of 2020, widespread community transmission in China had been ended, and restrictions were significantly eased.[35] Sporadic local outbreaks caused by imported cases have happened since then, which authorities responded to with testing and restrictions.[36] Different neighbourhoods or townships were classified into high-, medium- or low-risk based on the number of confirmed cases and whether there were cluster cases,[37] which formed the basis for the gradual easing of lockdown measures since March.[38] Lockdown in hard-hit Wuhan was officially lifted on 8 April.[39]

China is one of just a few of countries that have pursued a zero-COVID strategy, which aims to eliminate transmission of the virus within the country and allow resumption of normal economic and social activity.[40]

Despite concerns about automated social control, health codes generated by software have been used for contact tracing: only people with green code can move freely, while those with red or yellow code need to be reported to the government.[39][41] With domestic tourism first reopened among the pandemic-hit industries,[42][43] China's economy continued to broaden recovery from the recession during the pandemic, with stable job creation and record international trade growth, although retail consumption was still slower than predicted.[44][45] China was the only major economy to report economic growth in 2020.[46]

In July 2020, the government granted an emergency use authorization for two COVID-19 vaccines.[47][48] It has also pledged or provided humanitarian assistance to other countries dealing with the virus.[8][9]

Initial outbreak

Discovery

One of the earliest Wuhan MHC notices about the pneumonia epidemic. It was first posted on Weibo on 30 December 2019 and was confirmed by Wuhan CDC the next day (31 December).

Based on retrospective analysis published in

disease may have been the index case in the COVID-19 pandemic.[52][53] Although the first confirmed patient did not have any exposure to Huanan Seafood Market, an outbreak of the virus began among the people who had been exposed to the market nine days later.[19][54]

The outbreak went unnoticed until 26 December 2019, when

Jianghan District's Health Agency and Administration for Market Regulation closed down the seafood market and collected samples for testing.[57]

On 28 December 2019, Lili Ren, a virologist at the Chinese Academy of Medical Sciences & Peking Union Medical College in Beijing uploaded a partial sequence of the COVID-19 virus's structure to the United States National Institutes of Health's GenBank. The NIH did not publish the submission, as it did not include technical information required by the institute's rules, and attempts by the NIH to contact Ren went unanswered. On 17 January 2024, The Wall Street Journal released a report about the 28 December upload.[58]

The

SARS-CoV-2) was announced by Chinese scientists as the cause of the new disease.[60] Professor Yongzhen published the results to the online database GenBank on 11 January.[55]

On 14 January, the WHO tweeted:

Preliminary investigations conducted by the Chinese authorities have found no clear evidence of human-to-human transmission of the novel coronavirus (2019-nCoV) identified in Wuhan, China.

On 15 February 2021, WHO investigators in China said they had found evidence that the initial outbreak in Wuhan was more widespread than originally thought. They asked the Chinese government for permission to study hundreds of thousands of blood samples from Wuhan; as of 15 February, this permission had not been granted.[62]

Within three weeks of the first known cases, the government built sixteen large mobile hospitals in Wuhan and sent 40,000 medical staff to the city.[63]: 137 

A retrospective study of antibody prevalence estimated that close to 500,000 people in Wuhan may have been infected during the outbreak.[64]

On 22 January, Hubei launched a Class 2 Response to Public Health Emergency.[73] Ahead of the Hubei authorities, a Class 1 Response to Public Health Emergency, the highest response level was announced by the mainland province of Zhejiang on 23.[74][75] Guangdong and Hunan followed suit later on the day. On the following day, Hubei[68] and other 13 mainland provinces[76][77][78][79] also launched a Class 1 Response. By 29, all parts of mainland initiated a Class 1 Response after Tibet upgraded its response level on that day.[26]

The highest response level authorizes a provincial government to requisition resources under the administration to control the epidemic. The government was allowed to organize and coordinate treatment for the patients, make investigations into the epidemic area, declare certain areas in the province as an epidemic control area, issue compulsory orders, manage human movement, publish information and reports, sustain social stability and to do other work related to epidemic control.[80]
