Coronavirus Timeline

Wuhan, China experiences a dramatic increase in hospital traffic “beginning in late summer and early fall," according to a Harvard Medical School study. Dr. John Brownstein notes that there was “some level of social disruption” happening in October, “well before what was previously identified as the start of the novel coronavirus pandemic.”  

An audit internal to Hubei Province concludes that a “huge gap in staff and operating funds of the provincial CDC has seriously affected the normal performance of public health functions.”

Three researchers from the Wuhan Institute of Virology are hospitalized with flu-like symptoms.

A 55-year-old resident from Hubei province contracts COVID-19, according to data seen by the South China Morning Post, possibly the first coronavirus case.

The first coronavirus case now recognized by Chinese authorities is recorded in a Wuhan hospital. The patient was initially suspected to have been infected by an animal (likely a bat) in the Huanan Seafood Market, a narrative now in dispute as researchers propound alternative origins, including that lax security procedures in the Wuhan Institute of Virology led to its escape.

A month-long influenza outbreak begins, including in Wuhan, causing a 20-fold increase in influenza cases from the previous year. 

The first suspected human-to-human transmission is recorded by Wuhan doctors. A patient is observed to have the virus but denies ever visiting the seafood market.

Wuhan doctors suspect disease transmission from patients to medical staff, further evidence of human-to-human transmission and the first instance of a threat to health care workers. Wuhan hospitals have experienced a steady rise in infections since the first cases.

A French patient is confirmed to have the virus, marking the first known case outside of China. The sample from the patient was not analyzed until May 2020.

A Guangzhou-based genomics company sequences most of the virus, showing an “alarming similarity to…SARS.” Samples of the virus are distributed to at least six other genomics companies for testing.

Chinese social media censors introduce a list of coronavirus-related terms, including “Wuhan unknown pneumonia” and “unknown SARS,” to block from online discussions.

Taiwanese public health officials warn the World Health Organization (WHO) that the virus is spreading between humans. The WHO never publicizes the warning.

The Wuhan Public Security Bureau summons eight people to its headquarters, including Dr. Li Wenliang, who initially warned the public about the virus, accusing them of spreading “hoaxes.” Dr. Li signs a statement confessing to his “misdemeanor.” The fate of the other seven is unknown.

An official at the Hubei Provincial Health Commission orders a genomics company to cease “testing samples from Wuhan and to destroy all existing samples.” The company’s labs had sequenced the virus’s genetic code in December with results suggesting a highly infectious virus similar to SARS.

Retroactive antibody testing identified “probable” infections in people living in disparate corners of Ohio in early January.

China’s National Health Commission (NHC) orders institutions “not to publish any information related to the unknown disease” and orders labs to “transfer any samples they had to designated testing institutions or to destroy them.” The order did not specify any testing institutions.

U.S. Centers for Disease Control (CDC) Director Robert Redfield receives reports on the novel coronavirus from Chinese colleagues. The chief of staff to U.S. Health and Human Services Secretary Alex Azar informs the National Security Council.

Six days after its China Country Office was “informed of cases of pneumonia with unknown etiology” in Wuhan, the WHO “advises against the application of any travel or trade restrictions on China based on the information available on this event.”

The CDC offers to send a team to assist Chinese authorities; it never receives permission to enter the country.

Wuhan hosts annual, eleven-day meetings with local and Hubei provincial officials. Local officials reportedly “stymied” investigators from Beijing for fear of angering their superiors.

President Xi Jinping reportedly orders public officials to control the outbreak during a private meeting of top CCP leadership. The existence of the meeting was not reported by state media until February, in the face of heavy criticism from Chinese citizens.

Chinese authorities announce publicly that a novel coronavirus was behind the recent viral pneumonia outbreak.

Xinhua News Agency first reports on the outbreak.

The WHO praises the Chinese government: “Preliminary identification of a novel virus in a short period of time is a notable achievement and demonstrates China’s increased capacity to manage new outbreaks.” It also stresses that “the virus does not spread readily between people” and reiterates its advice against travel or trade restrictions on China. Privately, WHO officials were frustrated that the CCP had not yet released the virus’s genome; yet these concerns were not shared with the public

Chinese authorities share the virus’s genome with the rest of the world. The Chinese government had been in possession of the sequence since December 27.

Thailand reports its first case.

Nearly six weeks after Wuhan doctors raise the possibility of human-to-human transmission, the WHO issues a statement stressing that Chinese authorities recorded no cases of human-to-human transmission.

Hubei Provincial officials hold a teleconference with Ma Xiaowei, the head of China’s National Health Commission, who details the threat posed by the new virus. A memo from the teleconference raises the possibility of human-to-human transmission.

Japan records its first case of coronavirus.

The CCP issues an alert to all Chinese consulates “to prepare for and respond to a pandemic” by obtaining massive stocks of personal protective equipment. 

China’s Center for Disease Control and Prevention in Beijing initiates internally its highest-level emergency response, which includes directions to hospitals to take protective precautions and to begin tracking cases. The directions are marked “not to be publicly disclosed.”

Wuhan authorities allow nearly 40,000 to gather for the Lunar New Year celebration.

Chinese state media first reports that President Xi ordered officials to stop the virus; President Xi also makes a public statement, failing to mention human-to-human transmission.

Dr. Zhong Nanshan, a leading authority on respiratory health who rose to prominence for his role fighting SARS, confirms that the disease spreads from person-to-person. The head of China’s NHC investigatory team also confirms cases of human-to-human transmission in Guangdong province, indicating spread between provinces.

The CDC confirms the first American case, a Washington resident who had returned from China six days earlier.

WHO Director General Tedros Adhanom Ghebreyesus praises China for its “cooperation” and praises Xi Jinping for his “leadership and intervention” which had been “invaluable” to responding to the outbreak. A WHO Emergency Committee concludes that the virus does not constitute a Public Health Emergency of International Concern (PHEIC).

France records Europe’s first and second real-time cases.

Australia and Canada record their first coronavirus cases.

The Chinese government announces it will extend the Lunar New Year Holiday until February 2.

The Chinese government suspends group travel to foreign countries (individuals would still travel abroad unencumbered), three days after massive outbound traffic begins for the Lunar New Year. Over those days, travelers journeyed to Japan, South Korea, the United States, Italy, Spain, France, the United Kingdom, and South America. The RAND Corporation estimates that, at this time, China’s reported number of infections was undercounted by a factor of nearly 40.

The WHO declares the coronavirus a global health emergency, while expressing confidence in “China’s capacity to control the outbreak.” The organization recommends against border closures, visa restrictions, and quarantining of healthy visitors from affected regions.

Several Chinese provinces and cities extend the Lunar New Year holiday until at least February 13 to halt commerce and travel.

Iran presumptively cancels all flights to and from China. Privately owned Mahan Airlines (which has links to Iran’s Islamic Revolutionary Guard Corps) continues service between Tehran and China, including Wuhan, for at least another week.

CCP authorities order residents in Atush, in the Xinjiang Uighur Autonomous Region, to confine themselves in their homes for three weeks. Residents say they were given no prior warning and Uighur watchdog groups report widespread starvation in the area. Authorities never close Uighur detention camps.

Responding to the prior day’s announcement that the United States would suspend entry of foreign nationals who had visited China, Chinese officials criticize the move as “neither based in fact nor helpful” and “certainly not a gesture of goodwill.”

The first coronavirus death outside China is reported: a 44-year-old man in the Philippines.

The city of Wuhan completes construction on the makeshift Huoshenshan hospital in ten days, eliciting breathless praise from state media, which describe the accomplishment as “shocking.”

The Chinese embassy in Canberra criticizes Australia’s travel ban on entries from mainland China.

A California patient initially thought to have died from influenza is confirmed in April to be the first COVID-19 death in the U.S. The first U.S. death reported in real-time would not be until February 29 in Seattle.

Dr. Li Wenliang, considered by the Chinese public to be the foremost champion of spreading information about coronavirus, succumbs to the virus at the age of 33. His death leads to an outpouring of national anger over information suppression.

Hubei officials underreported cases by nearly half, with 2,478 reported and 5,918 recorded in internal documents. The average time from symptom onset to a positive test result is 23.3 days, and clinical diagnoses are recorded as “suspected cases” instead of “confirmed cases.” This practice would continue into the middle of the month. 

Shortly after Dr. Li’s death, the hashtag “#wewantfreedomofspeech” trends on Chinese social media platform Weibo. The same day, it is deleted by censors along with other related topics.

In response to criticism of CCP treatment of Uighur communities during the outbreak, Wang Xining, China’s number two diplomat in Australia, calls Uighur detention camps “training centers,” where people get “training for future jobs” and where residency is “mostly voluntary.”

30,000 Uighur workers, described by some as “dispensable labor” are sent back to factories. International watchdogs describe the move as “dangerous,” turning Uighurs into “commodities of the state” who would assume the risk of infection while stimulating the Chinese economy.

The Chinese government announces plans to publish a book, Great War, that details Xi Jinping’s “strategic vision and outstanding leadership” in combatting the virus in China, alongside a demonstration of the “advantages” of the “socialist system with Chinese characteristics” in handling such a crisis.
