This article lists the pages containing the chronology and epidemiology of SARS-CoV-2,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. At this stage it is not possible to determine precisely how humans in China were initially infected with SARS-CoV-2. Furthermore, some developments may become known or fully understood only in retrospect.
The COVID-19 pandemic, also known as the coronavirus pandemic, is an ongoing pandemic of coronavirus disease 2019 (COVID‑19), caused by severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2). The outbreak was first identified in Wuhan, China, in December 2019. The World Health Organization declared the outbreak a Public Health Emergency of International Concern on 30 January, and a pandemic on 11 March. As of 4 June 2020, more than 6.51 million cases of COVID-19 have been reported in more than 188 countries and territories, resulting in more than 386,000 deaths; more than 2.8 million people have recovered.
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the strain of coronavirus that causes coronavirus disease 2019 (COVID-19), a respiratory illness. Colloquially known as simply the coronavirus, it was previously referred to by its provisional name, 2019 novel coronavirus (2019-nCoV), and has also been called human coronavirus 2019. As described by the U.S. National Institutes of Health, it is the successor to SARS-CoV-1. SARS-CoV-2 is a positive-sense single-stranded RNA virus. It is contagious in humans, and the World Health Organization (WHO) has designated the ongoing pandemic of COVID-19 a Public Health Emergency of International Concern.
A coronavirus disease, coronavirus respiratory syndrome, coronavirus pneumonia, coronavirus flu, or any other variant, is a disease caused by members of the coronavirus (CoV) family.
Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). First identified in December 2019 in Wuhan, China, it resulted in an ongoing pandemic. The first case may be traced back to 17 November 2019. As of 3 June 2020, more than 6.44 million cases have been reported across 188 countries and territories, resulting in more than 382,000 deaths. More than 2.76 million people have recovered.
The ongoing COVID-19 pandemic was confirmed to have reached the United States in January 2020. The first confirmed case of local transmission was recorded in January, while the first known deaths happened in February. By the end of March, cases had occurred in all 50 U.S. states, the District of Columbia, and all inhabited U.S. territories except American Samoa. As of May 27, 2020, the U.S. had the most confirmed active cases and deaths in the world, and its death rate was 285 per million people, the ninth-highest rate globally.
COVID-19 testing can identify the SARS-CoV-2 virus and includes methods that detect the presence of the virus itself and those that detect antibodies produced in response to infection. Detection of antibodies can be used both for diagnosis and for population surveillance. Antibody tests show how many people have had the disease, including those whose symptoms were minor or who were asymptomatic, but may not find antibodies in someone with a current COVID-19 infection since antibodies may not show up for weeks. An accurate mortality rate of the disease and the level of herd immunity in the population can be determined from the results of this test. However, the duration and effectiveness of this immune response are still unclear.
The COVID-19 pandemic in San Marino 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 San Marino in February 2020.
A COVID-19 vaccine is a hypothetical vaccine against coronavirus disease 2019 (COVID‑19). Although no vaccine has completed clinical trials, there are multiple efforts in progress to develop such a vaccine. In February 2020, the World Health Organization (WHO) said it did not expect a vaccine against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative virus, to become available in less than 18 months. Previous attempts to develop a vaccine against the coronavirus diseases, SARS and MERS, established considerable knowledge about the structure and function of coronaviruses – which accelerated rapid development during early 2020 of varied technology platforms for a COVID-19 vaccine – but all the previous coronavirus vaccine candidates failed in early-stage clinical trials, with none being advanced to licensing.
The COVID-19 pandemic was confirmed to have reached South America on 26 February when Brazil confirmed a case in São Paulo. By 3 April, all countries and territories in South America had recorded at least one case.
During the COVID-19 pandemic, human rights violations including censorship, discrimination, arbitrary detention, xenophobia were reported from different parts of the world. Amnesty International has responded that "Human rights violations hinder, rather than facilitate, responses to public health emergencies, and undercut their efficiency." The World Health Organization has stated that stay-at-home measures for slowing down the pandemic must not be done at the expense of human rights.
The first case relating to the COVID-19 pandemic in the U.S. state of Connecticut was confirmed on March 8, although there had been multiple suspected cases before that point which tested negative. As of May 25, 2020, there were 40,873 positive cases and 3,742 deaths in the state. Some state officials have speculated that there may be thousands of undiagnosed cases in the state.
The COVID-19 pandemic in Papua New Guinea 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 Papua New Guinea on 20 March 2020. On 4 May, all known cases have recovered.
The COVID-19 pandemic in the Bahamas is part of the COVID-19 pandemic of coronavirus disease 2019 (COVID-19). The outbreak was identified in Wuhan, China, in December 2019, declared to be a Public Health Emergency of International Concern on 30 January 2020, and recognized as a pandemic by the World Health Organization on 11 March 2020. It was confirmed to have reached the Bahamas on 15 March 2020 with the announcement of the first case.
The first cases of the COVID-19 pandemic in Madhya Pradesh were confirmed on 20 March 2020. These were the first four cases in Jabalpur, Madhya Pradesh. Madhya Pradesh has confirmed a total of 8,588 cases, including 371 deaths and 5,445 recoveries, as of 3 June 2020.
The World Health Organization is a leading organization involved in the global coordination for mitigating the COVID-19 pandemic. On 5 January 2020, the WHO notified the world about "pneumonia of unknown cause" from China and subsequently followed up with investigating the disease. On 20 January, the WHO confirmed human-to-human transmission of the disease. On 30 January, the WHO declared the outbreak a Public Health Emergency of International Concern and warned all countries to prepare. On 11 March, WHO said that the outbreak constituted a pandemic. The WHO has spearheaded several initiatives like COVID-19 Solidarity Response Fund for fundraising for the pandemic and Solidarity Trial for investigating potential treatment options for the disease. In responding to the outbreak, the WHO has had to deal with political conflicts between member states, in particular between the United States and China.
Planning and preparing for pandemics has happened in countries and international organizations. The World Health Organization writes recommendations and guidelines, though there is no sustained mechanism to review countries' preparedness for epidemics and their rapid response abilities. National action depends on national governments.In 2005–2006, prior to the 2009 swine flu pandemic and during the decade following it, the governments in the United States, France, UK and others managed strategic health equipment stocks, but often reduced stocks after the 2009 pandemic in order to reduce costs.
This article documents the chronology and epidemiology of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for the COVID-19 pandemic, which was first detected in Wuhan, China. Some developments may become known or fully understood only in retrospect.
Coronavirus disease 2019 (COVID-19) has a relatively low case fatality rate, but the actual numbers of deaths are considerable given the huge scale of the pandemic. As of 20 May 2020, worldwide over 328,000 people have died due to COVID-19, while more than 1.9 million people have recovered. Deaths are more common in those aged over 60 years and those with co-morbidities. Most people affected with the disease recover without any particular treatment. Poor outcomes and mortality are associated with old age, profound disabilities and frailty.
This article documents the chronology and epidemiology of SARS-CoV-2 in June 2020, the virus responsible for the COVID-19 pandemic which originated in Wuhan, Hubei, mainland China. Some developments may become known or fully understood only in retrospect. Reporting on this pandemic began in December 2019.
The severity of COVID‑19 varies. The disease may take a mild course with few or no symptoms, resembling other common upper respiratory diseases such as the common cold. Mild cases typically recover within two weeks, while those with severe or critical diseases may take three to six weeks to recover. Among those who have died, the time from symptom onset to death has ranged from two to eight weeks.
