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 . The first human cases of COVID-19 occurred in Wuhan, People's Republic of China, on or about 17 November 2019. [ 2]
