The following is a timeline of the COVID-19 pandemic in the United States during 2021. [1]
The COVID-19 pandemic, also known as the coronavirus pandemic, is an ongoing global pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The novel virus was first identified in an outbreak in the Chinese city of Wuhan in December 2019. Attempts to contain it there failed, allowing the virus to spread to other areas of Asia and later worldwide. The World Health Organization (WHO) declared the outbreak a public health emergency of international concern on 30 January 2020, and a pandemic on 11 March 2020. As of 1 February 2023, the pandemic had caused more than 670 million cases and 6.83 million confirmed deaths, making it one of the deadliest in history.
The COVID-19 pandemic in the United States is a part of the worldwide pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). In the United States, it has resulted in 102,541,962 confirmed cases with 1,110,856 all-time deaths, the most of any country, and the twentieth-highest per capita worldwide. The COVID-19 pandemic ranks first on the list of disasters in the United States by death toll; it was the third-leading cause of death in the U.S. in 2020, behind heart disease and cancer. From 2019 to 2020, U.S. life expectancy dropped by 3 years for Hispanic and Latino Americans, 2.9 years for African Americans, and 1.2 years for white Americans. These effects persisted as U.S. deaths due to COVID-19 in 2021 exceeded those in 2020, and life expectancy continued to fall from 2020 to 2021.
The COVID-19 pandemic in Egypt is part of the worldwide pandemic of coronavirus disease 2019 caused by severe acute respiratory syndrome coronavirus 2. The virus was confirmed to have reached Egypt on 14 February 2020.
The COVID-19 pandemic in Togo is part of the ongoing worldwide pandemic of coronavirus disease 2019 caused by severe acute respiratory syndrome coronavirus 2. The virus was confirmed to have reached Togo in March 2020.
The COVID-19 pandemic in Nigeria is part of the worldwide pandemic of coronavirus disease 2019 caused by severe acute respiratory syndrome coronavirus 2. The first confirmed case in Nigeria was announced on 27 February 2020, when an Italian national in Lagos tested positive for the virus. On 9 March 2020, a second case of the virus was reported in Ewekoro, Ogun State, a Nigerian citizen who came into contact with the Italian national.
The COVID-19 pandemic in Tunisia is part of the ongoing pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The disease was confirmed to have reached Tunisia on 2 March 2020.
The COVID-19 pandemic in the Democratic Republic of the Congo is part of the worldwide pandemic of coronavirus disease 2019 caused by severe acute respiratory syndrome coronavirus 2. The virus was confirmed to have reached the Democratic Republic of the Congo on 10 March 2020. The first few confirmed cases were all outside arrivals.
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 Djibouti is part of the worldwide pandemic of coronavirus disease 2019 caused by severe acute respiratory syndrome coronavirus 2. The virus spread to Djibouti in March 2020. It is a novel infectious disease caused by severe acute respiratory syndrome coronavirus 2. Model-based simulations for Djibouti indicate that the 95% confidence interval for the time-varying reproduction number R t has been rising since August 2020 and exceeded 1.0 until April 2021.
The COVID-19 pandemic in Angola is 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 Burundi is part of the ongoing worldwide pandemic of coronavirus disease 2019 caused by severe acute respiratory syndrome coronavirus 2. The virus was confirmed to have reached Burundi on 25 March 2020.
The COVID-19 pandemic in Tanzania is 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 COVID-19 pandemic in Zambia is part of the ongoing worldwide pandemic of coronavirus disease 2019 caused by severe acute respiratory syndrome coronavirus 2. The virus was confirmed to have reached Zambia in March 2020.

The following is a timeline of the COVID-19 pandemic in the United States during 2020.
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 following is the timeline of the COVID-19 pandemic in India from January 2021 to the May 2021. The complexity of the COVID-19 data reporting in India has been scrutinized extensively because of the disagreement between the undocumented morbidity rate and the low rates of case fatality in comparison to other countries.
This article documents the chronology and epidemiology of SARS-CoV-2, the virus that causes the coronavirus disease 2019 (COVID-19) and is responsible for the COVID-19 pandemic, in January 2022. The first human cases of COVID-19 were identified in Wuhan, China, in December 2019.
