December 31, 2019: Chinese Health officials informed the World Health Organization about a cluster of 41 patients with a mysterious pneumonia. Most were connected to the Huanan Seafood Wholesale Market, a wet market in the city of Wuhan.

Though the first 41 cases were reported December 31, some reporting suggests the virus could have started spreading as early as November. The market may simply have boosted the transmission.

Researchers think the coronavirus originated in bats, then jumped to an intermediary species that passed it to people.

January 1, 2020: Chinese authorities closed the Huanan Seafood Wholesale Market.

Wuhan authorities banned the trade of live animals at wet markets soon after the first cases were confirmed. China has also banned the buying, selling, and transportation of wild animals in markets, restaurants, and online marketplaces across the country. 

January 7: Chinese authorities identified the virus that caused the illness as a new type of coronavirus.

Other viruses in the coronavirus family cause the common cold, pneumonia, and SARS. 

January 11: China recorded its first death linked to the novel coronavirus.

The first person to die was a 61-year-old man who was a frequent customer at the Huanan market.

January 13: The first coronavirus case outside China was reported in Thailand.

A 61-year-old female tourist in Thailand was diagnosed on January 13. She’d recently spent time in Wuhan. Airports in Hong Kong, Singapore, Thailand, and South Korea also began to screen passengers for fever.

January 20: The first US case was reported: a 35-year-old man in Snohomish County, Washington.


The man left Wuhan and landed at the Seattle-Tacoma International Airport on January 15. Though he initially showed no symptoms, he reported to an urgent care clinic with symptoms of pneumonia on January 19. He was diagnosed with the virus a day later.

January 23: Chinese authorities placed the 11-million-person city of Wuhan under quarantine, and the rest of the Hubei province days later.

The Hubei lockdowns affected an estimated 60 million people, making China’s action the largest quarantine in history at the time.

January 30: The WHO declared a “public-health emergency of international concern.”

The WHO’s determination of “global public-health emergency” has been around since 2005 and had been used five times before.

Those instances were the Ebola outbreak that started in 2013 in West Africa, another one that’s been ongoing in the Democratic Republic of Congo since 2018, the 2016 Zika epidemic, polio emerging in war zones in 2014, and the swine-flu pandemic in 2009.
