Coronavirus disease 2019 (COVID-19) is a contagious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The first case was identified in Wuhan, China, in December 2019. The disease has since spread worldwide, leading to an ongoing pandemic.
Preventive measures include physical or social distancing, quarantining, ventilation of indoor spaces, covering coughs and sneezes, hand washing, and keeping unwashed hands away from the face. The use of face masks or coverings has been recommended in public settings to minimise the risk of transmissions. Several vaccines have been developed and several countries have initiated mass vaccination campaigns.
Although work is underway to develop drugs that inhibit the virus, the primary treatment is currently symptomatic. Management involves the treatment of symptoms, supportive care, isolation, and experimental measures. (Full article...)
About the virus
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the virus that causes coronavirus disease 2019 (COVID-19), the respiratory illness responsible for the COVID-19 pandemic. 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 (HCoV-19 or hCoV-19).
SARS-CoV-2 is a positive-sense single-stranded RNA virus (and hence Baltimore class IV) that is contagious in humans. As described by the US National Institutes of Health, it is the successor to SARS-CoV-1, the virus that caused the 2002–2004 SARS outbreak. (Full article...)
About the symptoms and spread
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 rhinorrhea, cough, muscle pain, sore throat, fever, diarrhea, and breathing difficulties. People with 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 diarrhea. In people without prior ears, nose, and throat disorders, loss of taste combined with loss of smell is associated with COVID-19.
As is common with infections, there is a delay between the moment a person first becomes infected and the appearance of the first symptoms. The median delay for COVID-19 is four to five days. Most symptomatic people experience symptoms within two to seven days after exposure, and almost all will experience at least one symptom within 12 days. (Full article...)
COVID-19 spreads from person to person mainly through the respiratory route after an infected person coughs, sneezes, sings, talks or breathes. A new infection occurs when virus-containing particles exhaled by an infected person, either respiratory droplets or aerosols, get into the mouth, nose, or eyes of other people who are in close contact with the infected person. During human-to-human transmission, an average 1000 infectious SARS-CoV-2 virions are thought to initiate a new infection. (Full article...)

National responses
A total of 192[2] countries and territories have had at least one case of COVID-19 so far. Due to the pandemic in Europe, many countries in the Schengen Area have restricted free movement and set up border controls. National reactions have included containment measures such as quarantines and curfews (known as stay-at-home orders, shelter-in-place orders, or lockdowns). The WHO's recommendation on curfews and lockdowns is that they should be short-term measures to reorganise, regroup, rebalance resources, and protect health workers who are exhausted. To achieve a balance between restrictions and normal life, the long-term responses to the pandemic should consist of strict personal hygiene, effective contact tracing, and isolating when ill.

Economic impact
The COVID-19 pandemic has had far-reaching economic consequences beyond the spread of the disease itself and efforts to quarantine it. As the SARS-CoV-2 virus has spread around the globe, concerns have shifted from supply-side manufacturing issues to decreased business in the services sector. The pandemic caused the largest global recession in history, with more than a third of the global population at the time being placed on lockdown.
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. (Full article...)
Workplace
Hazard controls for COVID-19 in workplaces are the application of occupational safety and health methodologies for hazard controls to the prevention of coronavirus disease 2019 (COVID-19). The proper hazard controls in the workplace depend on the worksite and job task, based on an occupational risk assessment of sources of exposure, disease severity in the community, and risk factors of individual workers who may be vulnerable to contracting COVID-19.
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.

Misinformation
The COVID-19 pandemic has resulted in misinformation and conspiracy theories about the scale of the pandemic and the origin, prevention, diagnosis, and treatment of the disease. False information, including intentional disinformation, has been spread through social media, text messaging, and mass media. Journalists have been arrested for allegedly spreading fake news about the pandemic. False information has also been propagated by celebrities, politicians, and other prominent public figures. A Cornell University study found that US President Donald Trump was "likely the largest driver" of the COVID-19 misinformation infodemic in English-language media. The spread of COVID-19 misinformation by governments has also been significant. (Full article...)
Testing
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. Molecular tests for viral presence through its molecular components are used to diagnose individual cases and to allow public health authorities to trace and contain outbreaks. Antibody tests (serology immunoassays) 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. (Full article...)
