The FBI concluded with "moderate confidence" that COVID-19 may have been created in a laboratory, based in part on genomic analysis conducted by scientists at the National Center for Medical Intelligence. [98] On 20 March 2023, the COVID-19 Origin Act of 2023 was signed into law. On June 23, 2023, the Biden administration released its report ...
The history of coronaviruses is an account of the discovery of the diseases caused by coronaviruses and the diseases they cause. It starts with the first report of a new type of upper-respiratory tract disease among chickens in North Dakota, U.S., in 1931. The causative agent was identified as a virus in 1933.
The timeline of the COVID-19 pandemic lists the articles containing the chronology and epidemiology of SARS-CoV-2, [1] the virus that causes the coronavirus disease 2019 and is responsible for the COVID-19 pandemic. The first human cases of COVID-19 occurred in Wuhan, People's Republic of China, on or about 17 November 2019. [2]
The report added weight to calls for a broader probe into the theory that the COVID-19 virus could have escaped from a laboratory. [ 6 ] [ 7 ] However, a WHO report states "introduction through a laboratory incident was considered to be an extremely unlikely pathway". [ 3 ]
By late November 2019, coronavirus disease 2019 had broken out in Wuhan, China. [2]As reported in Clinical Infectious Diseases on November 30, 2020, 7,389 blood samples collected between December 13, 2019, and January 17, 2020, by the American Red Cross from normal donors in nine states (California, Connecticut, Iowa, Massachusetts, Michigan, Oregon, Rhode Island, Washington and Wisconsin ...
Transcription of the interrupted repeats was also noted for the first time; this was the first full characterization of CRISPR. [19] [20] By 2000, Mojica and his students, after an automated search of published genomes, identified interrupted repeats in 20 species of microbes as belonging to the same family. [21]
To avoid confusion with the disease SARS, the WHO sometimes refers to SARS‑CoV‑2 as "the COVID-19 virus" in public health communications [34] [35] and the name HCoV-19 was included in some research articles.
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".
