89-731: The start of the 2020 season was postponed due to the COVID-19 pandemic before ultimately being cancelled on June 30. In conjunction with a contraction of Minor League Baseball beginning with the 2021 season, the Appalachian League was reorganized as a collegiate summer baseball league , and the Cardinals were replaced by the Johnson City Doughboys , a new franchise in the revamped league designed for rising college freshmen and sophomores. In 1955, Johnson City and

178-639: A Gallup poll in September 2021, 45% of full-time U.S. employees worked from home, including 25% who worked from home all of the time and 20% who worked from home part of the time. 91% of those who work remotely (fully or partially) hoped to continue to do so after the pandemic. Among all workers, 54% believed that their company's culture would be unchanged by remote work, while 12% believed it would improve and 33% predicted it would deteriorate. Gallup found in February 2023 that, among remote-capable employees in

267-683: A Wi-Fi -equipped laptop or tablet computers , smartphones , and desktop computers , using software such as Zoom , Webex , Microsoft Teams , Google Meet , Slack , and WhatsApp . In his 1992 travelogue Exploring the Internet , Carl Malamud described a " digital nomad " who "travels the world with a laptop, setting up FidoNet nodes ." In 1993, Random House published the Digital Nomad's Guide series of guidebooks by Mitch Ratcliffe and Andrew Gore. The guidebooks, PowerBook , AT&T EO Personal Communicator , and Newton's Law , used

356-625: A healthy diet are also recommended. Supportive care in severe cases includes treatment to relieve symptoms , fluid therapy , oxygen support and prone positioning , and medications or devices to support other affected vital organs. More severe cases may need treatment in hospital. In those with low oxygen levels, use of the glucocorticoid dexamethasone is recommended to reduce mortality. Noninvasive ventilation and, ultimately, admission to an intensive care unit for mechanical ventilation may be required to support breathing. Extracorporeal membrane oxygenation (ECMO) has been used to address

445-416: A network bridge . The terms telecommuting and telework were coined by Jack Nilles in 1973. In 1979, five IBM employees were allowed to work from home as an experiment. By 1983, the experiment was expanded to 2,000 people. By the early 1980s, branch offices and home workers were able to connect to organizational mainframes using personal computers and terminal emulators . In 1995, the motto that "work

534-627: A variant of concern (VoC) or a variant of interest (VoI). Many of these variants have shared the more infectious D614G . As of May 2023, the WHO had downgraded all variants of concern to previously circulating as these were no longer detected in new infections. Sub-lineages of the Omicron variant (BA.1 – BA.5) were considered separate VoCs by the WHO until they were downgraded in March 2023 as no longer widely circulating. As of 24 September 2024 ,

623-512: A U.S. Labor Department study published, millions of Americans ceased working from home by 2022, and the number of employers reporting teleworking decreasing to the level before pandemic levels. From August to September 2022, approximately 72 percent of private-sector businesses reported little to no telework among workers, compared to roughly 60 percent from July to September 2021. During the Information Age , many startups were founded in

712-409: A common location or permanent because all collaborators of the group are at the common work site. Same location means that the coworkers can get to each other's workspaces with a short walk and communicate via face-to-face interactions. Also, during meetings or small group meetings, a major advantage of collocated work is that individuals are able to move from one meeting to another, simply by overhearing

801-493: A comprehensive international study. Such deaths include deaths due to healthcare capacity constraints and priorities, as well as reluctance to seek care (to avoid possible infection). Further research may help distinguish the proportions directly caused by COVID-19 from those caused by indirect consequences of the pandemic. In May 2022, the WHO estimated the number of excess deaths by the end of 2021 to be 14.9 million compared to 5.4 million reported COVID-19 deaths, with

890-466: A conversation, seeing what someone is working on, and being aware of how long they had worked on it with or without progress. In addition, during these meetings, coworkers can observe someone's reaction by being able to see his/her gesture or glance. This allows for one to make sure that the group has common ground prior to moving on. Also, coworkers have access to common spaces for group interactions and have mutual access to significant shared information. In

979-414: A fifth concept of organizational management was proposed. Organizational management is the "practices by which management activities are part of shaping the fundamental premises for collaboration without proximity" There are two types of work that explain the geographical distance between coworkers/collaborators. Collocated work is the case in which team members are at the same location. Distributed work

1068-595: A large number of people". During the COVID-19 pandemic, as with other pandemics, the meaning of this term has been challenged. The end of a pandemic or other epidemic only rarely involves the total disappearance of a disease, and historically, much less attention has been given to defining the ends of epidemics than their beginnings. The ends of particular epidemics have been defined in a variety of ways, differing according to academic field, and differently based on location and social group. An epidemic's end can be considered

1157-567: A major organizational transformation. However, the implementation of remote work during COVID-19 was hurried, and new technologies and operating systems had to be implemented without previous testing or training. Organizations reported concerns about losses in culture and productivity whilst workers were more concerned about declines in social interactions, internet connectivity and increased workload. Additionally, 25% of remote-working Americans were resistant to employer mandates to return to in-office work. The abrupt transition to remote work during

1246-451: A median range of 0.24% to 1.49%. IFRs rise as a function of age (from 0.002% at age 10 and 0.01% at age 25, to 0.4% at age 55, 1.4% at age 65, 4.6% at age 75, and 15% at age 85). These rates vary by a factor of ≈10,000 across the age groups. For comparison, the IFR for middle-aged adults is two orders of magnitude higher than the annualised risk of a fatal automobile accident and much higher than

1335-399: A more geographically diverse pool of applicants, and allows employees to relocate to a place they would prefer to live. Opponents of remote work argue that remote telecommunications technology has been unable to replicate the advantages of face-to-face interaction , that employees may be more easily distracted and may struggle to maintain separation between work and non-work spheres without

1424-676: A peak around 2–3 days per week, an April 2023 survey of 1,000 office workers found a peak of five days per week required onsite. Requirements for fewer days were progressively rarer, culminating in 0% saying they must work onsite less than once per month. A May 2022 survey by the Office for National Statistics (ONS) found that 14% of working arrangements were fully remote, 24% were hybrid, and 46% were fully onsite. A June 2023 survey of 2,000 full-time workers found that 6% of working arrangements were fully remote, 46% were hybrid, and 48% were fully onsite. An Autumn Survey by ONS found that more than

1513-854: A quarter of working adults in Great Britain (28%) had hybrid arrangements. They found that those aged over 30, parents and managers and professionals were the most likely to log on from home. For those able to have a hybrid arrangement, the ONS said there were significant perks, including an average of 56 minutes saved from commuting, and spending an average of 24 minutes more on sleep and rest and 15 minutes more on exercise, sports and wellbeing. There are several key terms associated with collocated work and distributed work. The most important concepts are common ground, coupling in work, collaboration readiness, and technology readiness. This section will briefly define these four concepts. Common ground refers to

1602-824: A random sample have consistently found that total infections considerably exceed the reported case counts. Many countries, early on, had official policies to not test those with only mild symptoms. The strongest risk factors for severe illness are obesity, complications of diabetes , anxiety disorders, and the total number of conditions. During the start of the COVID-19 pandemic it was not clear whether young people were less likely to be infected, or less likely to develop symptoms and be tested. A retrospective cohort study in China found that children and adults were just as likely to be infected. Among more thorough studies, preliminary results from 9 April 2020 found that in Gangelt ,

1691-440: A rapid transition to remote work for white-collar workers around the world, which largely persisted even after restrictions were lifted. Proponents of having a geographically distributed workforce argue that it reduces costs associated with maintaining an office, grants employees autonomy and flexibility that improves their motivation and job satisfaction, eliminates environmental harms from commuting, allows employers to draw from

1780-426: A separate question, 7% said their employer does not allow hybrid working. A March 2023 survey of 2,016 adults found a roughly even distribution of required onsite days per week peaking at two and three days at about 16% each. However, it found a large spike in five days per week, the most common response at over 35%. About 13% were required to work fewer than one day per week. Countering the above results suggesting

1869-461: A social phenomenon, not just a biological one. Time reported in March 2024 that expert opinions differ on whether or not COVID-19 is considered endemic or pandemic, and that the WHO continued to call the disease a pandemic on its website. During the initial outbreak in Wuhan , the virus and disease were commonly referred to as "coronavirus", "Wuhan coronavirus", "the coronavirus outbreak" and

1958-459: A team must be pooled together. To do so, the team must make sure that they are on common ground in terms of knowledge and representation of the problem. Care must be taken to note that to achieve common ground when collaborating, differences are constructively managed, rather than downplayed. This is because collaboration differs from compromise. Technology readiness is a company or groups willingness and ability to use technology. Companies require

2047-547: A technical infrastructure if they are going to adopt technologies in the company. In particular, they require the habits, including those of preparation, regular access, attention given to others’ need for information, in order to effectively use the necessary technology for distributed work. Researchers repeatedly see that failure of distributed work often results from attempts to introduce new technologies to organizations or communities that are not yet comfortable with technologies that are already in place. The following chart explains

2136-451: A test. Conversely, deaths of people who died from underlying conditions following a positive test may be included. Countries such as Belgium include deaths from suspected cases, including those without a test, thereby increasing counts. Official death counts have been claimed to underreport the actual death toll, because excess mortality (the number of deaths in a period compared to a long-term average) data show an increase in deaths that

2225-435: A third of all working days are remote, slashing corporate real estate expenditures, and up from 5% before the pandemic. Bloom believes quickly progressing technology has facilitated and will continue the trend, but drawbacks for some kinds of positions will remain. A September 2022 study surveyed workers from 26 countries in mid-2021 and early 2022. Its respondents work from home an average of 1.5 days per week. According to

2314-518: Is associated with COVID-19 and is reported in as many as 88% of cases. The disease is mainly transmitted via the respiratory route when people inhale droplets and small airborne particles (that form an aerosol ) that infected people exhale as they breathe, talk, cough, sneeze, or sing. Infected people are more likely to transmit COVID-19 when they are physically close to other non-infected individuals. However, infection can occur over longer distances, particularly indoors. SARS‑CoV‑2 belongs to

2403-611: Is discouraged altogether by the World Health Organization (WHO), due to limited evidence of its efficacy. The severity of COVID-19 varies. It may take a mild course with few or no symptoms, resembling other common upper respiratory diseases such as the common cold . In 3–4% of cases (7.4% for those over age 65) symptoms are severe enough to cause hospitalisation. 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,

2492-439: Is intended to provide acquired immunity against severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2), the virus that causes coronavirus disease 2019 ( COVID-19 ). Prior to the COVID-19 pandemic, an established body of knowledge existed about the structure and function of coronaviruses causing diseases like severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS). This knowledge accelerated

2581-490: Is not explained by COVID-19 deaths alone. Using such data, estimates of the true number of deaths from COVID-19 worldwide have included a range from 18.2 to 33.5 million (≈27.4 million) by 18 November 2023 by The Economist , as well as over 18.5 million by 1 April 2023 by the Institute for Health Metrics and Evaluation and ≈18.2 million (earlier) deaths between 1 January 2020, and 31 December 2021, by

2670-672: Is something you do, not something you travel to" was coined. Variations of this motto include: "Work is what we do, not where we are." Since the 1980s, the normalization of remote work has been on a steady incline. For example, the number of Americans working from home grew by 4 million from 2003 to 2006, and by 1983 academics were beginning to experiment with online conferencing. In the 1990s and 2000s, remote work became facilitated by technology such as collaborative software , virtual private networks , conference calling , videotelephony , internet access , cloud computing , voice over IP (VoIP), mobile telecommunications technology such as

2759-550: Is the practice of working at or from one's home or another space rather than from an office . The practice began on a small scale in the 1970s, when technology was developed that linked satellite offices to downtown mainframes through dumb terminals using telephone lines as a network bridge . It became more common in the 1990s and 2000s, facilitated by internet technologies such as collaborative software on cloud computing and conference calling via videotelephony . In 2020, workplace hazard controls for COVID-19 catalyzed

2848-452: Is the ratio of deaths to diagnoses. This metric can be misleading because of the delay between symptom onset and death and because testing focuses on symptomatic individuals. Based on Johns Hopkins University statistics, the global CFR was 1.02 percent (6,881,955 deaths for 676,609,955 cases) as of 10 March 2023. The number varies by region and has generally declined over time. Several variants have been named by WHO and labelled as

2937-406: Is the seventh known coronavirus to infect people, after 229E , NL63 , OC43 , HKU1 , MERS-CoV , and the original SARS-CoV . The standard method of testing for presence of SARS-CoV-2 is a nucleic acid test , which detects the presence of viral RNA fragments. As these tests detect RNA but not infectious virus, its "ability to determine duration of infectivity of patients is limited." The test

3026-443: Is the term used to explain team members who are not in the same physical location when working on a project. There are many differences, similarities, benefits, and obstacles between these two types of work. In order to distinguish between collocated and distributed work, it is necessary to go into more detail. Collocated work is the case in which the team members are at the same physical location. This may be temporary due to travel to

3115-614: Is typically done on respiratory samples obtained by a nasopharyngeal swab ; however, a nasal swab or sputum sample may also be used. The WHO has published several testing protocols for the disease. Preventive measures to reduce the chances of infection include getting vaccinated, staying at home or spending more time outdoors, avoiding crowded places, keeping distance from others, wearing a mask in public, ventilating indoor spaces, managing potential exposure durations, washing hands with soap and water often and for at least twenty seconds, practising good respiratory hygiene, and avoiding touching

3204-514: The Huanan Seafood Wholesale Market there, but it is possible that human-to-human transmission began earlier. Molecular clock analysis suggests that the first cases were likely to have been between October and November 2019. The scientific consensus is that the virus is most likely of a zoonotic origin, from bats or another closely related mammal. While other explanations such as speculations that SARS-CoV-2

3293-407: The Institute for Health Metrics and Evaluation estimating the true number of cases as of early 2022 to be in the billions. One measure that public health officials and policymakers have used to monitor the pandemic and guide decision-making is the test positivity rate ("percent positive"). According to Johns Hopkins in 2020, one benchmark for a "too high" per cent positive is 5%, which was used by

3382-718: The Salem Rebels were declared co-champions of the Appalachian League when their final playoff series was canceled due to rain. From 1986 to 2019, Johnson City reached the playoffs by virtue of winning their division or clinching a playoff spot eight times. The results of their postseason play during this time was as follows. Many of the players fielded by Johnson City have gone on to distinguish themselves in Major League Baseball . COVID-19 pandemic The COVID-19 pandemic (also known as

3471-602: The basic reproduction number (R 0 ) for COVID-19 in January 2020 were between 1.4 and 2.5, but a subsequent analysis claimed that it may be about 5.7 (with a 95 per cent confidence interval of 3.8 to 8.9). In December 2021, the number of cases continued to climb due to several factors, including new COVID-19 variants. As of that 28   December, 282,790,822 individuals worldwide had been confirmed as infected. As of 14 April 2022 , over 500 million cases were confirmed globally. Most cases are unconfirmed, with

3560-479: The coronavirus pandemic and COVID 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

3649-474: The variants of interest as specified by the World Health Organization are BA.2.86 and JN.1, and the variants under monitoring are JN.1.7, KP.2, KP.3, KP.3.1.1, JN.1.18, LB.1, and XEC. Symptoms of COVID-19 are variable, ranging from mild symptoms to severe illness. Common symptoms include headache, loss of smell and taste , nasal congestion and runny nose , cough, muscle pain , sore throat , fever, diarrhoea , and breathing difficulties . People with

3738-429: The "Wuhan coronavirus outbreak", with the disease sometimes called "Wuhan pneumonia ". In January 2020, the WHO recommended 2019-nCoV and 2019-nCoV acute respiratory disease as interim names for the virus and disease per 2015 international guidelines against using geographical locations (e.g. Wuhan, China), animal species, or groups of people in disease and virus names in part to prevent social stigma . WHO finalised

3827-649: The European Union who were aged 15–64, usually worked from home. By country, the percentage of workers that worked from home was highest in Finland (25.1%), Luxembourg (23.1%), Ireland (21.5%), Austria (18.1%), and the Netherlands (17.8%) and lowest in Bulgaria (1.2%), Romania (2.5%), Croatia (3.1%), Hungary (3.6%), and Latvia (4.5%). In 2023, economist and telework expert Nicholas Bloom said about

3916-525: The Hudson's Bay Company showed a variety of control mechanisms including selection techniques, information requirements, and direct local oversight through its distributed practices of socialization , communication , and participation. Managers found that "common sense" was not enough to encourage everyone to comply. In the early 1970s, technology was developed that linked satellite offices to downtown mainframes through dumb terminals using telephone lines as

4005-571: The Telework Enhancement Act of 2010 required each executive agency in the United States to establish policy allowing remote work to the maximum extent possible, so long as employee performance is not diminished. During the COVID-19 pandemic , millions of workers began remote work for the first time. Cities in which the population of remote workers increased significantly were referred to as Zoom towns . According to

4094-503: The U.S., 20% worked on-site, 28% exclusively remote and 52% hybrid. According to the United States Office of Personnel Management , 50% of all U.S. federal workers were eligible to work remotely and agencies saved more than $ 180 million because of remote work in fiscal 2020. A September 2022 study surveyed workers in mid-2021 and early 2022. Its 2,079 US subjects worked from home on average 1.6 days per week, similar to

4183-640: The WHO in the past. As of 10 March 2023, more than 6.88   million deaths had been attributed to COVID-19. The first confirmed death was in Wuhan on 9 January 2020. These numbers vary by region and over time, influenced by testing volume, healthcare system quality, treatment options, government response, time since the initial outbreak, and population characteristics, such as age, sex, and overall health. Multiple measures are used to quantify mortality. Official death counts typically include people who died after testing positive. Such counts exclude deaths without

4272-419: The WHO, US, European Union, and Australia. On 12 November 2022, the WHO released its Global Vaccine Market Report. The report indicated that "inequitable distribution is not unique to COVID-19 vaccines"; countries that are not economically strong struggle to obtain vaccines. On 14 November 2022, the first inhalable vaccine was introduced, developed by Chinese biopharmaceutical company CanSino Biologics , in

4361-411: The bottom end of the earning spectrum experience reduced remuneration. Utility bills also increased during the COVID-19 pandemic in an inconsistent manner. Utility bills for minorities and lower income individuals were more likely to increase because they lived in housing that was older, with less effective insulation and without energy-efficient appliances . The increase in electricity also came due to

4450-448: The broad family of viruses known as coronaviruses . It is a positive-sense single-stranded RNA (+ssRNA) virus, with a single linear RNA segment. Coronaviruses infect humans, other mammals, including livestock and companion animals, and avian species. Human coronaviruses are capable of causing illnesses ranging from the common cold to more severe diseases such as Middle East respiratory syndrome (MERS, fatality rate ≈34%). SARS-CoV-2

4539-588: The centre of a major infection cluster in Germany, 15 per cent of a population sample tested positive for antibodies . Screening for COVID-19 in pregnant women in New York City , and blood donors in the Netherlands, found rates of positive antibody tests that indicated more infections than reported. Seroprevalence -based estimates are conservative as some studies show that persons with mild symptoms do not have detectable antibodies. Initial estimates of

4628-419: The characteristics that contribute to achieving common ground that are inherent in various communication media. It is important to note that those who are remote complain about the difficulty of establishing common ground. This is because when individuals are connected by audio conferencing, it is difficult to tell who is speaking if you do not know the participant well. However, people with video can engage in

4717-760: The city of Shanghai, China. For the first two years of the pandemic, no specific and effective treatment or cure was available. In 2021, the European Medicines Agency's (EMA) Committee for Medicinal Products for Human Use (CHMP) approved the oral antiviral protease inhibitor , Paxlovid (nirmatrelvir plus the HIV antiviral ritonavir ), to treat adult patients. FDA later gave it an EUA. Most cases of COVID-19 are mild. In these, supportive care includes medication such as paracetamol or NSAIDs to relieve symptoms (fever, body aches, cough), adequate intake of oral fluids and rest. Good personal hygiene and

4806-446: The coworkers need to share information and are rewarded for sharing it. It is important to note that one should not attempt to introduce groupware and remote technologies in organizations and communities that do not have a culture of sharing and collaboration. Common ground is often used in collaboration, where a team is out to solve a complex problem. In order to solve a complex problem, the different skills and perspectives of members in

4895-484: The cumulative number of infected individuals (including asymptomatic and undiagnosed infections and excluding vaccinated infected individuals). It is expressed in percentage points. Other studies refer to this metric as the infection fatality risk . In November 2020, a review article in Nature reported estimates of population-weighted IFRs for various countries, excluding deaths in elderly care facilities, and found

4984-441: The development of various vaccine platforms during early 2020. The initial focus of SARS-CoV-2 vaccines was on preventing symptomatic and severe illness. The COVID-19 vaccines are widely credited for their role in reducing the severity and death caused by COVID-19. As of March 2023, more than 5.5 billion people had received one or more doses (11.8 billion in total) in over 197 countries. The Oxford-AstraZeneca vaccine

5073-513: The eyes, nose, or mouth with unwashed hands. Those diagnosed with COVID-19 or who believe they may be infected are advised by healthcare authorities to stay home except to get medical care, call ahead before visiting a healthcare provider, wear a face mask before entering the healthcare provider's office and when in any room or vehicle with another person, cover coughs and sneezes with a tissue, regularly wash hands with soap and water and avoid sharing personal household items. A COVID-19 vaccine

5162-474: The general public beginning in December 2020, made available through government and international programs such as COVAX , aiming to provide vaccine equity . Treatments include novel antiviral drugs and symptom control. Common mitigation measures during the public health emergency included travel restrictions , lockdowns , business restrictions and closures, workplace hazard controls , mask mandates , quarantines, testing systems, and contact tracing of

5251-654: The global average of 1.5 days per week. An April 2023 survey of 558 central London workers' requirements for onsite working found the most common response was two and three days per week at 26% and 21% of responses respectively. Fewer cited one, four, and five days, each making 8–11% of responses. Having no requirement was second-most common at 25% of responses. It also found that about 18% of vacancies listed by London companies in February 2023 were hybrid or remote, up from about 4% in February 2020. An early 2023 survey of 2,049 workers found that 35% must work onsite for two days, 33% for three days, and 33% always work from home. In

5340-692: The global average of 1.5 days per week. These results may vary based on the type of sample collected. Certain groups may have fewer office-workers, e.g., in more urban locations or industries requiring more manual labour. As such groups may find remote working impossible, their presence or absence in these samples may affect the analysis. A June 2022 survey of 56 offices found that 51% had no policy requiring office attendance, 18% requiring two days per week, 11% requiring three days per week, and 20% had policy set at team-level. A September 2022 study surveyed workers in mid-2021 and early 2022. Its 1,501 UK subjects worked from home on average two days per week – above

5429-511: The homes of entrepreneurs who lacked financial resources. A 2020 study of the then-ongoing pandemic estimated that 93% of world workers lived in countries with some sort of workplace closure. This figure was composed of: 32% living in countries with required closures for all but essential workplaces; 42% in countries where specific firms or worker categories had been closed; and 19% in countries with only recommended workplace closures. The extensive use of remote work under COVID-19 constituted

5518-665: The infected. The pandemic caused severe social and economic disruption around the world, including the largest global recession since the Great Depression . Widespread supply shortages , including food shortages , were caused by supply chain disruptions and panic buying . Reduced human activity led to an unprecedented temporary decrease in pollution . Educational institutions and public areas were partially or fully closed in many jurisdictions, and many events were cancelled or postponed during 2020 and 2021. Telework became much more common for white-collar workers as

5607-487: The issue of respiratory failure. Existing drugs such as hydroxychloroquine , lopinavir/ritonavir , and ivermectin are not recommended by US or European health authorities, as there is no good evidence they have any useful effect. The antiviral remdesivir is available in the US, Canada, Australia, and several other countries, with varying restrictions; however, it is not recommended for use with mechanical ventilation, and

5696-419: The knowledge that participants have in common, and they are aware that they have this information in common. Common ground is not just established from some general knowledge about the person's background, but also through specific knowledge learned from several different cues that are available at the moment, including the person's appearance and behavior during conversational interactions. The figure below, shows

5785-576: The majority of the unreported 9.5 million deaths believed to be direct deaths due the virus, rather than indirect deaths. Some deaths were because people with other conditions could not access medical services . A December 2022 WHO study estimated excess deaths from the pandemic during 2020 and 2021, again concluding ≈14.8 million excess early deaths occurred, reaffirming and detailing their prior calculations from May as well as updating them, addressing criticisms. These numbers do not include measures like years of potential life lost and may make

5874-495: The official names COVID-19 and SARS-CoV-2 on 11 February 2020. Tedros Adhanom Ghebreyesus explained: CO   for corona , VI   for virus , D   for disease and 19 for when the outbreak was first identified (31 December 2019). WHO additionally uses "the COVID-19 virus" and "the virus responsible for COVID-19" in public communications. WHO named variants of concern and variants of interest using Greek letters . The initial practice of naming them according to where

5963-503: The order in which various collaboration technologies should be adopted in organizations to allow the employees to become familiar with and learn each new technology. The list below shows the observed order in which various collaboration technologies were adopted and used in different organizations. As this chart shows, advanced technologies should be introduced in small steps. These key concepts are important because they help differentiate between collocated and distributed work. Later on,

6052-412: The other hand, loosely coupled work has fewer dependencies or is more routine. It is important that all group members establish common ground about the task, goals, and procedures before working, but this type of work overall requires less frequent or less complicated interactions. Collaboration readiness is a groups willingness to work together and share their ideas. Using shared technology assumes that

6141-427: The outbreak as having become a pandemic on 11 March. COVID-19 symptoms range from asymptomatic to deadly, but most commonly include fever, sore throat , nocturnal cough , and fatigue. Transmission of the virus is often through airborne particles . Mutations have produced many strains (variants) with varying degrees of infectivity and virulence . COVID-19 vaccines were developed rapidly and deployed to

6230-407: The pandemic 2021's leading cause of death . The time between symptom onset and death ranges from   6 to 41 days, typically about 14 days. Mortality rates increase as a function of age. People at the greatest mortality risk are the elderly and those with underlying conditions. The infection fatality ratio (IFR) is the cumulative number of deaths attributed to the disease divided by

6319-495: The pandemic evolved. Misinformation circulated through social media and mass media , and political tensions intensified . The pandemic raised issues of racial and geographic discrimination , health equity , and the balance between public health imperatives and individual rights . The WHO ended the PHEIC for COVID-19 on 5 May 2023. The disease has continued to circulate, but as of 2024, experts were uncertain as to whether it

6408-534: The pandemic led to an increase in both physical and mental health issues among workers; a lack of dedicated workspaces and distractions from others in the home were common negative influences on health and well-being, while effective communication with coworkers was supportive of health and well-being. The transition also increased the amount of time that individuals spent sitting at a workstation by up to two hours more per day, yet, most workers indicated being as productive working remotely as compared to office work before

6497-529: The pandemic. Supporting workers to identify effective approaches for boundary management between home and work across physical spaces, social interactions, and use of time are critical. The transition to remote work during the pandemic highlighted the importance of access and equity among individual workers to support productivity and well-being. The remote work arrangement during COVID-19 was better for higher-paid and higher-management personnel in terms of productivity and reported well-being; whereas individuals at

6586-519: The people using their utilities at different times of the day. A study highlighted the behavioral changes and adaptations that occurred as they transitioned to remote work. It was found that while some educators adapted well to the new mode of working, many-faced significant challenges such as the lack of necessary infrastructure, including reliable internet access and adequate digital devices. This disparity often resulted in unequal teaching and learning experiences for both educators and students. Moreover,

6675-434: The physical separation, and that the reduced social interaction may lead to feelings of isolation. Between 1670 and 1826, management had to rely on trust and control to successfully manage distributed work. During this time, in addition to dispersed operations that relied heavily on a combination of explicit information and detailed record-keeping, more tacit and situated knowledge developed through socialization. For example,

6764-415: The population's age structure and the age-specific pattern of infections. There have also been reviews that have compared the fatality rate of this pandemic with prior pandemics, such as MERS-CoV. For comparison the infection mortality rate of seasonal flu in the United States is 0.1%, which is 13 times lower than COVID-19. Another metric in assessing death rate is the case fatality ratio (CFR), which

6853-462: The risk of dying from seasonal influenza . In December 2020, a systematic review and meta-analysis estimated that population-weighted IFR was 0.5% to 1% in some countries (France, Netherlands, New Zealand, and Portugal), 1% to 2% in other countries (Australia, England, Lithuania, and Spain), and about 2.5% in Italy. This study reported that most of the differences reflected corresponding differences in

6942-496: The same infection may have different symptoms, and their symptoms may change over time. Three common clusters of symptoms have been identified: one respiratory symptom cluster with cough, sputum , shortness of breath, and fever; a musculoskeletal symptom cluster with muscle and joint pain, headache, and fatigue; a cluster of digestive symptoms with abdominal pain, vomiting, and diarrhoea. In people without prior ear, nose, and throat disorders, loss of taste combined with loss of smell

7031-567: The spread of the virus within the community, and mitigation strategies (commonly known as " flattening the curve ") that attempt to lessen the effects of the virus on society, but which still tolerate some level of transmission within the community. These initial strategies can be pursued sequentially or simultaneously during the acquired immunity phase through natural and vaccine-induced immunity . Remote work Remote work (also called telecommuting , telework , work from home —or WFH as an initialism, hybrid work , and other terms)

7120-594: The study noted the psychological strain experienced by education workers, stemming from increased workloads and the blurring of boundaries between work and personal life. The necessity of establishing clear boundaries and providing adequate support systems was emphasized to ensure the well-being and productivity of education workers in a remote setting. A 2024 PNAS study found that remote work dispersed economic activity away from city centers, in particular in cities with high levels of remote work. In 2020, 12.3% of employed persons, including 13.2% of women and 11.5% of men, in

7209-424: The subtle negotiation that establishes local common ground- whether what was said was understood or not, whether the conversation can proceed or needs repair. Overall, the more common ground people can establish, the easier the communication will be and the greater the productivity . Coupling refers to the extent and kind of communication required by the work. Tightly coupled work is work that strongly depends on

7298-468: The talents of collections of workers and is non-routine, and even ambiguous. Components of this type of work are highly interdependent, meaning that the work requires frequent, complex communication among group members, with short feedback loops and multiple streams of information. This type of communication is very difficult in remote locations, mostly because technology does not support rapid back and forth conversations or awareness and repair of ambiguity. On

7387-458: The term "digital nomad" to refer to the increased mobility and more powerful communication and productivity technologies that facilitated remote work. European hacker spaces of the 1990s led to coworking ; the first such space opened in 2005. The new economy production no longer requires people to work together in the same physical space to access the tools and resources they need to produce their work and allows for distributed work. In 2010,

7476-411: The time from symptom onset to death has ranged from two to eight weeks. Prolonged prothrombin time and elevated C-reactive protein levels on admission to the hospital are associated with severe course of COVID-19 and with a transfer to intensive care units (ICU). Between 5% and 50% of COVID-19 patients experience long COVID , a condition characterised by long-term consequences persisting after

7565-694: The typical convalescence period of the disease. The most commonly reported clinical presentations are fatigue and memory problems, as well as malaise , headaches, shortness of breath , loss of smell, muscle weakness , low fever and cognitive dysfunction . Many countries attempted to slow or stop the spread of COVID-19 by recommending, mandating or prohibiting behaviour changes, while others relied primarily on providing information. Measures ranged from public advisories to stringent lockdowns. Outbreak control strategies are divided into elimination and mitigation. Experts differentiate between elimination strategies (known as " zero-COVID ") that aim to completely stop

7654-543: The variants were identified (e.g. Delta began as the " Indian variant") is no longer common. A more systematic naming scheme reflects the variant's PANGO lineage (e.g., Omicron 's lineage is B.1.1.529) and is used for other variants. SARS-CoV-2 is a virus closely related to bat coronaviruses , pangolin coronaviruses, and SARS-CoV . The first known outbreak (the 2019–2020 COVID-19 outbreak in mainland China ) started in Wuhan , Hubei, China, in December 2019. Many early cases were linked to people who had visited

7743-443: Was accidentally released from a laboratory have been proposed, as of 2021 these were not supported by evidence. Official "case" counts refer to the number of people who have been tested for COVID-19 and whose test has been confirmed positive according to official protocols whether or not they experienced symptomatic disease. Due to the effect of sampling bias , studies which obtain a more accurate number by extrapolating from

7832-457: Was still a pandemic. Pandemics and their ends are not well-defined, and whether or not one has ended differs according to the definition used. As of 24 November 2024, COVID-19 has caused 7,075,455 confirmed deaths. The COVID-19 pandemic ranks as the fifth- deadliest pandemic or epidemic in history . In epidemiology , a pandemic is defined as "an epidemic occurring over a very wide area, crossing international boundaries, and usually affecting

7921-509: Was the most widely used. According to a June 2022 study, COVID-19 vaccines prevented an additional 14.4 million to 19.8 million deaths in 185 countries and territories from 8 December 2020 to 8 December 2021. On 8 November 2022, the first recombinant protein-based COVID-19 vaccine (Novavax's booster Nuvaxovid ) was authorised for use in adults in the United Kingdom. It has subsequently received endorsement/authorisation from
