Of the first 41 confirmed cases of 2019-nCoV infection, two-thirds were found to have a link with the Huanan Seafood Wholesale Market, which also sold live animals. The earliest reported symptoms occurred on 1 December 2019, in a person who did not have any exposure to the market or to the remaining 40 affected people. As the number of cases has increased, the significance of the market lessened.

Since 31 December 2019, some regions and countries near China tightened their screening of selected travelers. The Centers for Disease Control and Prevention (CDC) of the United States later issued a Level 1 travel watch. Guidances and risk assessments were shortly posted by others including the European Centre for Disease Prevention and Control and Public Health England. In China, airports, railway stations and coach stations installed infrared thermometers. Travelers with a measured fever are taken to medical institutions after being registered and given masks. A real-time reverse transcription-polymerase Chain Reaction (RRT-PCR) test was used to confirm new cases of coronavirus infection.

The first reported death due to 2019-nCoV infection was a 61-year-old man on 9 January 2020 who was first admitted to a Wuhan hospital on 27 December 2019.

On 17 January, a research group from the Imperial College London in the United Kingdom published a report that there had been 1,723 cases (95% confidence interval, 427–4,471) with the onset of symptoms by 12 January. This was based on the pattern of the initial spread to Thailand and Japan. They also concluded that "self-sustaining human-to-human transmission should not be ruled out", which has since been confirmed. As further cases came to light, they later recalculated that there may be 4,000 symptomatic cases of 2019-nCoV in Wuhan City by 18 January (uncertainty range of 1,000 to 9,700). A Hong Kong University group has reached a similar conclusion as the earlier study, with additional detail on transport within China.

The virus spread to other Chinese provinces in early and mid-January 2020, helped by the Chinese new year migration. On 20 January, China reported a sharp rise in cases with nearly 140 new patients, including two people in Beijing and one in Shenzhen.

As of 20 January 2020, 282 confirmed cases of 2019-nCoV have been reported from four countries including China (278 cases), Thailand (2 cases), Japan (1 case) and the Republic of Korea (1 case)

In Asia, Hong Kong, Mongolia, Nepal, North Korea, Russia, and Vietnam have also responded with border tightening/closures with mainland China.

On 23 January 2020, the number of reported confirmed cases of 2019-nCoV has increased by 267 cases since the last situation report published on 22 January 2020. As of 23 January, China reported cases in 25 provinces (autonomous regions and municipalities). Twenty-five percent of confirmed cases reported by China have been classified by Chinese health authorities as seriously ill (from Wubei Province: (16% severely ill, 5% critically ill, and 4% having died).

On 24 January, British Prime Minister Boris Johnson called an emergency COBRA meeting to discuss the outbreak and country preparedness.

A specialty hospital named Huoshenshan Hospital has been constructed as a countermeasure against the outbreak and to better quarantine the patients. Wuhan City government had demanded that a state-owned enterprise construct such a hospital "at the fastest speed" comparable to that of the SARS outbreak in 2003. On 24 January, Wuhan authorities specified its planning, saying they planned to have Huoshenshan Hospital built within six days of the announcement and it will be ready to use on 3 February. Upon opening, the specialty hospital has 1,000 beds and takes up 30,000 square meters. The hospital is modeled after the Xiaotangshan Hospital, which was fabricated for the SARS outbreak of 2003, itself built in only seven days. State media reported that there were 7,000 workers and nearly 300 units of construction machinery on the site at peak.

By 24 January 2020, a total of 15 cities in the Hubei, including Wuhan, were placed under similar quarantine measures.

This created chaos, as residents rushed to supermarkets to stock food as soon as the lockdown was declared until the authorities reversed their decision. Caixin said, that the wording of Shantou's initial declaration was "unprecedentedly strict" and will severely affect residents' lives if implemented as-is. Shantou's Department for Outbreak Control later clarified, that they will not restrict traveling, and all they would do, is to sterilize vehicles used for transportation. A total of 2,014 confirmed 2019-nCoV cases have been reported globally reported by the WHO.

On 27 and 28 January 2020, Xiangyang respectively closed its railway stations and suspended all ferry operations, after shutting down its airport and intercity bus services earlier.

On 30 January 2020, following confirmation of human-to-human transmission outside of China and the increase in number of cases in other countries, the WHO declared the outbreak a Public Health Emergency of International Concern (PHEIC), the sixth PHEIC since the measure was first invoked during the 2009 Swine flu pandemic. Tedros clarified that the PHEIC, in this case, was "not a vote of no confidence in China", but because of the risk of global spread, especially to low- and middle-income countries without robust health systems.

Outside Mainland China, some cruise ships were quarantined after passengers developed symptoms or tested positive for 2019-nCoV.

On 12 February, the Hubei government adopted a broader definition of confirmed cases, which now includes clinically diagnosed patients diagnosed by their symptoms and CT scans but without a nucleic acid test, which can take days to process and delay treatment. "Using CT scans that reveal lung infection would help patients receive treatment as soon as possible and improve their chances of recovery," the provincial health commission said. This new methodology accounts for the sharp increase in Hubei's daily confirmed cases: 13,332 of the 14,840 newly confirmed cases in the province on 12 February were diagnosed clinically under the new definition.

On the 14th of February, the WHO declared that the confirmed cases count has surpassed 50000 and reached 64437. And that the number of deaths is 1383.

This virus may be on its way and you need to be ready. You have a duty to your citizens, you have a duty to the world to be ready," urging that the right response measures could help the world avoid “the worst of it." Ryan further stated that the current data does not warrant public health officials to declare a global pandemic, saying that the declaration would mean "we’re essentially accepting that every human on the planet will be exposed to that virus."

With SARS in 2003, there was no transmission to others during incubation and the early symptoms. With COVID-19, there is evidence of early transmission. Ben Cowling, professor of epidemiology at Hong Kong University, said, “This coronavirus is more comparable to influenza.” It is not known how and if Covid-19 may resurface, though some fear it could follow a similar path to the 1918-1919 flu pandemic in which the second and third waves were more deadly than the first.

However, virologist and U.S. National Institute of Allergy and Infectious Diseases director Dr. Anthony Fauci indicated that the Pfizer vaccine targets the spike protein used to infect cells by the virus. Some issues left to be answered are how long the vaccine offers protection, and if it offers the same level of protection to all ages.
