The development of COVID-19 tests was a major public health priority during the early months of the COVID-19 pandemic. In January 2020, scientists from China published the first genetic sequences of SARS-CoV-2 via virological.org , [ 3 ] a "hub for prepublication data designed to assist with public health activities and research".

The US CDC's COVID-19 laboratory test kit. COVID-19 testing involves analyzing samples to assess the current or past presence of SARS-CoV-2, the virus that cases COVID-19 and is responsible for the COVID-19 pandemic. The two main types of tests detect either the presence of the virus or antibodies produced in response to infection.
In February 2020, a team led by Shi Zhengli at the institute were the first to identify, analyze and name the genetic sequence of the novel coronavirus (2019-nCoV), upload it to public databases for scientists around the world to understand, [27] [28] [29] and publish papers in Nature. [30]
[110] [111] US CDC developed its own testing kit after China shared the genetic sequence on 10 January and deployed it to detect the first coronavirus case. The testing kit used three small genetic sequences instead of two used by Germany. The test kits were found to be defective because the third sequence, or "probe", gave inconclusive results ...
The researchers found genetic evidence of the coronavirus in four of them, including one in front of wildlife stall A. That drain was still testing positive for SARS-CoV-2 in mid-February.
[15] [16] On 2 December 2020, the United Kingdom's Medicines and Healthcare products Regulatory Agency (MHRA) gave temporary regulatory approval for the Pfizer–BioNTech vaccine, [17] [18] becoming the first country to approve this vaccine and the first country in the Western world to approve the use of any COVID‑19 vaccine.
The species was merged with Rat coronavirus (discovered in 1970 [23]) and Puffinosis coronavirus (discovered in 1982 [59]) as Murine coronavirus in 2009. [60] 229E and OC43 were collectively named Human respiratory virus but merged as Human coronavirus 229E (HCoV-229E) in 2009. [61]
The first human cases of COVID-19 occurred in Wuhan, People's Republic of China, on or about 17 November 2019. [2] The first confirmed human case in the United States was on 19 January 2020. The World Health Organization declared the COVID-19 outbreak a Public Health Emergency of International Concern (PHEIC) on 30 January 2020, and first ...
