  1. Prevention Face masks and respiratory hygiene The CDC and WHO recommend individuals wear non-medical face coverings in public settings where there is an increased risk of transmission and where social distancing measures are difficult to maintain. This recommendation is meant to reduce the spread of the disease by asymptomatic and pre-symtomatic individuals and is complementary to established preventive measures such as social distancing. Face coverings limit the volume and travel distance of expiratory droplets dispersed when talking, breathing, and coughing. Many countries and local j
  2. Prevention Strategies for preventing transmission of the disease include maintaining overall good personal hygiene, washing hands, avoiding touching the eyes, nose, or mouth with unwashed hands, and coughing or sneezing into a tissue, and putting the tissue directly into a waste container. Those who may already have the infection have been advised to wear a surgical mask in public. Physical distancing measures are also recommended to prevent transmission. Health care providers taking care of someone who may be infected are recommended to use standard precautions, contact precautions, and
  3. Diagnosis 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. Viral testing The standard test for current infection with SARS-CoV-2 uses RNA testing of respiratory secretions collected using a nasopharyngeal swab, though it is possible to test other samples. This test uses real-time rRT-PCR which detects the presence of viral RNA fragments. A number of laboratories and companies have developed serological tests, which detect antib
  4. Cause Transmission COVID‑19 is a new disease, and many of the details of its spread are still under investigation. It spreads easily between people—easier than influenza but not as easily as measles. People are most infectious when they show symptoms (even mild or non-specific symptoms), but may be infectious for up to two days before symptoms appear (pre-symptomatic transmission). They remain infectious an estimated seven to twelve days in moderate cases and an average of two weeks in severe cases. People can also transmit the virus without showing any symptom (asymptomatic transmissio
  5. Signs and symptoms The usual incubation period (the time between infection and symptom onset) ranges from one to 14 days, and is most commonly five days. Some infected people have no symptoms, known as asymptomatic or presymptomatic carriers; transmission from such a carrier is considered possible. As at 6 April, estimates of the asymptomatic ratio range widely from 5 to 80 percent. 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 (phleg
  6. Epidemiology Deaths Most people who contract COVID-19 recover. For those who do not, the time between the onset of symptoms and death usually ranges from 6 to 41 days, typically about 14 days. As of 30 July 2020, approximately 664,000 deaths had been attributed to COVID-19. In China, as of 14 June, about 80 percent of deaths were recorded in those aged over 60, and 75 percent had pre-existing health conditions including cardiovascular diseases and diabetes. Obese individuals are at increased risk of severe illness from COVID-19. The first confirmed death was in Wuhan on 9 January 2
  7. Epidemiology Background On 31 December 2019, the World Health Organization (WHO) detected reports of a cluster of viral pneumonia cases of unknown cause in Wuhan, Hubei, and an investigation was launched at the start of January 2020. On 30 January, the WHO declared the outbreak a Public Health Emergency of International Concern (PHEIC)—7,818 cases confirmed globally, affecting 19 countries in five WHO regions. Several early infected people had visited Huanan Seafood Wholesale Market; the virus is therefore thought to be of zoonotic origin. The virus that caused the outbreak is know
  8. The COVID‑19 pandemic, also known as the coronavirus pandemic, is an ongoing global pandemic of coronavirus disease 2019 (COVID‑19), caused by severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2). The outbreak was first identified in December 2019 in Wuhan, China The World Health Organization declared the outbreak a Public Health Emergency of International Concern on 30 January 2020 and a pandemic on 11 March. As of 30 July 2020, more than 16.9 million cases of COVID‑19 have been reported in more than 188 countries and territories, resulting in more than 664,000 deaths; more than 9.89
