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), first identified in December 2019 in Wuhan, China. The World Health Organisation declared the outbreak a Public Health Emergency of International Concern in January 2020 and a pandemic in March 2020. As of 21 November 2020, more than 57.9   million cases have been confirmed, with more than 1.37   million deaths attributed to COVID-19. Common symptoms include fever, cough, fatigue, breathing difficulties, and loss of smell and taste. Complications may include pneumonia and acute respiratory distress syndrome. The incubation period is typically around five days but may range from one to 14 days. There are several vaccine candidates in development, although none has completed clinical trials. Although work is underway to develop drugs that inhibit the virus, the primary treatment is currentl

Epidemiology

For country-level data, see: COVID-19 pandemic by country and territory Cases 57,974,667 Deaths 1,378,411 As of 21 November 2020 Africa · Asia · Europe · North America Oceania · South America Background Although it is still unknown exactly where the outbreak first started, several early infected people had visited Huanan Seafood Wholesale Market, located in Wuhan, Hubei, China. On 11 February 2020, the World Health Organization (WHO) named the disease "COVID-19", which is short for coronavirus disease 2019. The virus that caused the outbreak is known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a newly discovered virus closely related to bat coronaviruses, pangolin coronaviruses, and SARS-CoV. The scientific consensus is that COVID-19 has a natural origin. The probable bat-to-human infection may have been among people processing bat carcasses and guano in the production of traditional Chinese medicines. The earliest known person with symptoms was la

Signs and symptoms

Image
Symptoms of COVID-19 can be relatively non-specific; the two most common symptoms are fever (88 percent) and dry cough (68 percent). Less common symptoms include fatigue, respiratory sputum production (phlegm), loss of the sense of smell, loss of taste, shortness of breath, muscle and joint pain, sore throat, headache, chills, vomiting, coughing out blood, diarrhea, and rash. Among those who develop symptoms, approximately one in five may become more seriously ill and have difficulty breathing. Emergency symptoms include difficulty breathing, persistent chest pain or pressure, sudden confusion, difficulty waking, and bluish face or lips; immediate medical attention is advised if these symptoms are present. Further development of the disease can lead to complications including pneumonia, acute respiratory distress syndrome, sepsis, septic shock, and kidney failure.

Diagnosis

Image
COVID-19 can provisionally be diagnosed on the basis of symptoms and confirmed using reverse transcription polymerase chain reaction (RT-PCR) testing of infected secretions or CT imaging of the chest. On 29 September 2020, a letter in Lancet highlighted the increasing likelihood of overestimating of COVID-19 incidence as more asymptomatic people are included in RT-PCR testing with consequent "misdirection of policies regarding lockdowns and school closures," noting that the false-positive rate in the UK is currently unknown, with "preliminary estimates … somewhere between 0·8% and 4·0%". The letter called for "stricter standards … in laboratory testing, … and pretest probability assessments … including symptoms, previous medical history of COVID-19 or presence of antibodies, any potential exposure to COVID-19, and likelihood of an alternative diagnosis." Viral testing The standard test for presence of SARS-CoV-2 uses RNA testing of respiratory secretions c
