The virus is primarily spread between people during close contact, most often via small droplets produced by coughing, sneezing, and talking. The droplets usually fall to the ground or onto surfaces rather than travelling through air over long distances. However, research as of June 2020[update] has shown that speech-generated droplets may remain airborne for tens of minutes. Less commonly, people may become infected by touching a contaminated surface and then touching their face. It is most contagious during the first three days after the onset of symptoms, although spread is possible before symptoms appear, and from people who do not show symptoms.
Close contact is defined as less than one metre (~3.3 feet) by the WHO and within ~1.8 metres (six feet) by the CDC.
An uncovered cough can travel up to 8.2 metres (27 feet).
Location: Countries, territories, and international conveyances where cases were diagnosed. The nationality of the infected and the origin of infection may vary. For some countries, cases are split into respective territories and noted accordingly.
Cases: This number shows the cumulative number of confirmed human cases reported to date. The actual number of infections and cases is likely to be higher than reported. Reporting criteria and testing capacity vary between locations. The total number of cases may not necessarily represent an aggregate sum of all entries in this column as it relies on aggregate sources and not local sources.
Deaths: Reporting criteria vary between locations. The total number of deaths may not necessarily represent an aggregate sum of all entries in this column as it relies on aggregate sources and not local sources.
Recoveries: May not correspond to actual current figures and not all recoveries may be reported. Reporting criteria vary between locations. The total number of recoveries may not necessarily represent an aggregate sum of all entries in this column as it relies on aggregate sources and not local sources.
Total numbers worldwide. Some locations, including North Korea, have yet to report cases.
Figures do not include the unincorporated territories of Puerto Rico, Guam, Northern Mariana Islands, and U.S. Virgin Islands, all of which are listed separately.
Not all states or overseas territories report recovery data.
Cases include clinically diagnosed cases as per CDC guidelines.
Recoveries and deaths include probable deaths and people released from quarantine as per CDC guidelines.
Figures from the United States Department of Defense are only released on a branch-by branch basis since April 2020, without distinction between domestic and foreign deployment, and cases may be reported to local health authorities.
Cases for the USS Theodore Roosevelt, currently docked at Guam, are reported separate from national figures but included in the Navy's totals.
Since 6 June, the Brazilian government has ordered the Ministry of Health to stop reporting the total number of deaths and active cases. After this, the National Council of Health Secretaries assumed the function of reporting the total number of deaths and active cases.
The Chilean Ministry of Health considered all cases as a "recovered" after 14 days since the initial symptoms of the virus, no matter the health situation of the infected or if following tests indicate the continuing presence of the virus. The only exception were casualties, which are not included as recovered.
Deaths only include cases with positive PCR tests and catalogued as "COVID-19 related death" by the Civil Registry and Identification Service. This number is informed on the daily reports of the Ministry of Health. A report with the total number of deaths, including suspected cases without PCR test, is released weekly since 20 June 2020. In the latest report (28 June 2020), the number of total deaths is 8,935.
The British cruise ship Diamond Princess was in Japanese waters, and the Japanese administration was asked to manage its quarantine, with the passengers having not entered Japan. Therefore, this case is included in neither the Japanese nor British official counts. The World Health Organization classifies the cases as being located "on an international conveyance".
As of 23 March 2020, according to figures from just over 40 per cent of all GPs in Norway, 20,200 patients have been registered with the "corona code" R991. The figure includes both cases where the patient has been diagnosed with coronavirus infection through testing, and where the GP has used the "corona code" after assessing the patient's symptoms against the criteria by the Norwegian Institute of Public Health.
As of 24 March 2020, the Norwegian Institute of Public Health estimates that between 7,120 and 23,140 Norwegians are infected with the coronavirus.
Excluding the cases from Diamond Princess cruise ship which are classified as "on an international conveyance". Ten cases, including one fatality recorded by the Australian government.
The number of recoveries is an estimate based on reported cases which were reported at least two weeks ago and there is no other monitoring data on the course of the disease. The exact number of recoveries is not known, as only a small proportion of patients have been hospitalized.
Recoveries are presumed. Defined as "An individual testing positive for coronavirus who completes the 14 day self-isolation period from the onset of symptoms who is at home on day 15, or an individual who is discharged from hospital following more severe symptoms."
Global stock markets fell on 24 February 2020 due to a significant rise in the number of COVID-19 cases outside mainland China. By 28 February 2020, stock markets worldwide saw their largest single-week declines since the 2008 financial crisis. Global stock markets crashed in March 2020, with falls of several percent in the world's major indices. As the pandemic spreads, global conferences and events across technology, fashion, and sports are being cancelled or postponed. While the monetary impact on the travel and trade industry is yet to be estimated, it is likely to be in the billions and increasing. Read more...
OSHA considers healthcare and mortuary workers exposed to known or suspected person with COVID-19 to be at high exposure risk, which increases to very high exposure risk if workers perform aerosol-generating procedures on, or collect or handle specimens from, known or suspected person with COVID-19. Hazard controls appropriate for these workers include engineering controls such as negative pressure ventilation rooms, and personal protective equipment appropriate to the job task. Read more...
COVID-19 testing involves analyzing samples to assess the current or past presence of SARS-CoV-2. The two main branches detect either the presence of the virus or of antibodies produced in response to infection. Tests for viral presence are used to diagnose individual cases and to allow public health authorities to trace and contain outbreaks. Antibody tests instead show whether someone once had the disease. They are less useful for diagnosing current infections because antibodies may not develop for weeks after infection. It is used to assess disease prevalence, which aids the estimation of the infection fatality rate. Read more...
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.

Poland's Ministry of National Defence admits its army briefly invaded and occupied the Czech Republic for several days last month in a "misunderstanding", the Polish soldiers took up positions near a chapel on the Czech side of the border in Moravia as part of coronavirus measures, and prevented Czech visitors from the site.
