Answer 1

Answer:

COVID-19 (coronavirus disease 2019) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), previously known as the 2019 novel coronavirus (2019-nCoV), a strain of coronavirus. The first cases were seen in Wuhan, China, in late December 2019 before spreading globally 1,2,10. The current outbreak was officially recognised as a pandemic on 11 March 2020 44.

Current imaging best practice advises that CT chest is not used to diagnose COVID-19, but maybe helpful in assessing for complications 115. The non-specific imaging findings are most commonly of atypical or organising pneumonia, often with a bilateral, peripheral, and basal predominant distribution 32. No effective treatment or vaccine exists currently (April 2020) 20.

The World Health Organisation (WHO) originally called this illness "novel coronavirus-infected pneumonia (NCIP)", and the virus itself had been provisionally named "2019 novel coronavirus (2019-nCoV)" 1.

On 11 February 2020, the WHO officially renamed the clinical condition COVID-19 (a shortening of COronaVIrus Disease-19) 15. Coincidentally, on the same day, the Coronavirus Study Group of the International Committee on Taxonomy of Viruses rename*d the virus "severe acute respiratory syndrome coronavirus 2" (SARS-CoV-2) 16,22,46. The names of both the disease and the virus should be fully capitalised, except for the 'o' in the viral name, which is in lowercase 16,22,41.

The official virus name is similar to SARS-CoV, the virus strain that caused epidemic severe acute respiratory syndrome (SARS) in 2002-2004, potentially causing confusion 38. The WHO has stated it will use "COVID-19 virus" or the "virus that causes COVID-19" instead of its official name, SARS-CoV-2 when communicating with the public 45.

As of 5 May 2020, the number of cases of confirmed COVID-19 globally is over 3.5 million 5. COVID-19 has now been diagnosed in 187 territories, in six continents according to an online virus tracker created by the medical journal, The Lancet, and hosted by Johns Hopkins University 5. As of 5 May 2020, the United States had more than 1 million cases, with a further eight countries with >100,000 cases, 29 countries with 10,000 to 100,000 confirmed cases, and 52 countries with between 1000 and 10,000 confirmed cases 5.
