The following is a timeline of the COVID-19 pandemic in the United States during 2021. [1]
The COVID-19 pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), began with an outbreak of COVID-19 in Wuhan, China, in December 2019. It spread to other areas of Asia, and then worldwide in early 2020. The World Health Organization (WHO) declared the outbreak a public health emergency of international concern (PHEIC) on 30 January 2020, and assessed the outbreak had become a pandemic on 11 March.
On December 31, 2019, China announced the discovery of a cluster of pneumonia cases in Wuhan. The first American case was reported on January 20, and Health and Human Services Secretary Alex Azar declared a public health emergency on January 31. Restrictions were placed on flights arriving from China, but the initial U.S. response to the pandemic was otherwise slow in terms of preparing the healthcare system, stopping other travel, and testing. The first known American deaths occurred in February and in late February President Donald Trump proposed allocating $2.5 billion to fight the outbreak. Instead, Congress approved $8.3 billion with only Senator Rand Paul and two House representatives voting against, and Trump signed the bill, the Coronavirus Preparedness and Response Supplemental Appropriations Act, 2020, on March 6. Trump declared a national emergency on March 13. The government also purchased large quantities of medical equipment, invoking the Defense Production Act of 1950 to assist. By mid-April, disaster declarations were made by all states and territories as they all had increasing cases. A second wave of infections began in June, following relaxed restrictions in several states, leading to daily cases surpassing 60,000. By mid-October, a third surge of cases began; there were over 200,000 new daily cases during parts of December 2020 and January 2021.

The COVID-19 pandemic in Nigeria was a part of the worldwide pandemic of coronavirus disease 2019 caused by severe acute respiratory syndrome coronavirus 2.

The first confirmed cases of COVID-19 in the U.S. state of Michigan were discovered on March 10, 2020, one day before the outbreak of the disease was officially declared a global pandemic by the World Health Organization. As of December 20, 2022, 2,977,727 cases have been identified, causing 40,657 deaths.
The COVID-19 pandemic in Sudan was a part of the worldwide pandemic of coronavirus disease 2019 caused by severe acute respiratory syndrome coronavirus 2. The virus was confirmed to have reached Sudan in March 2020.
The COVID-19 pandemic in Angola was a part of the worldwide pandemic of coronavirus disease 2019 caused by severe acute respiratory syndrome coronavirus 2. The virus was confirmed to have spread to Angola in late March 2020, with the first two cases being confirmed on 21 March.

The COVID-19 pandemic in Tanzania was a part of the ongoing worldwide pandemic of coronavirus disease 2019 caused by severe acute respiratory syndrome coronavirus 2. The COVID-19 pandemic was confirmed to have reached Tanzania in March 2020.

The following is a timeline of the COVID-19 pandemic in the United States during 2020.
The COVID-19 pandemic was confirmed to have reached the Sahrawi Arab Democratic Republic in July 2020. As of 19 June 2023, there are 2154 confirmed cases, of which 2064 have fully recovered, and the deaths have reached 90.
This article documents the chronology and epidemiology of SARS-CoV-2 in January 2021, the virus which causes the coronavirus disease 2019 (COVID-19) and is responsible for the COVID-19 pandemic. The first human cases of COVID-19 were identified in Wuhan, China, in December 2019.
The CDC publishes official numbers of COVID-19 cases in the United States. The CDC estimates that, between February 2020 and September 2021, only 1 in 1.3 COVID-19 deaths were attributed to COVID-19. The true COVID-19 death toll in the United States would therefore be higher than official reports, as modeled by a paper published in The Lancet Regional Health – Americas. One way to estimate COVID-19 deaths that includes unconfirmed cases is to use the excess mortality, which is the overall number of deaths that exceed what would normally be expected. From March 1, 2020, through the end of 2020, there were 522,368 excess deaths in the United States, or 22.9% more deaths than would have been expected in that time period.
The Beta variant, (B.1.351), was a variant of SARS-CoV-2, the virus that causes COVID-19. One of several SARS-CoV-2 variants initially believed to be of particular importance, it was first detected in the Nelson Mandela Bay metropolitan area of the Eastern Cape province of South Africa in October 2020, which was reported by the country's health department on 18 December 2020. Phylogeographic analysis suggests this variant emerged in the Nelson Mandela Bay area in July or August 2020.
