Timeline of the COVID-19 pandemic

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 (COVID-19) and is responsible for the COVID-19 pandemic.

Main article: COVID-19 pandemic

The first human cases of COVID-19 were identified in Wuhan, People's Republic of China, in December 2019.[2] The World Health Organization declared the COVID-19 outbreak a Public Health Emergency of International Concern on 30 January 2020, and a pandemic on 11 March 2020.[3][4][5] At this moment (October 2022), we cannot conclusively determine precisely how humans in mainland China were initially or previously infected with the virus, called SARS-CoV-2.[6] Furthermore, some developments may become known or fully understood only in retrospect.
