"COVID-19 (coronavirus disease-2019) is an infectious respiratory illness caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a betacoronavirus. Diagnosis of COVID-19 requires a positive RT-PCR test; imaging is not considered diagnostic and is reserved for assessing disease severity and complications 4,8. When present, imaging findings are those of an atypical or organising pneumonia 9."

"The disease is COVID-19 (a shortening of COronaVIrus Disease-2019), and the causative virus is severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) 3."
"SARS-CoV-2 emerged in late 2019 and is now endemic 3. The World Health Organisation (WHO) ended the COVID-19 public emergency on 5 May 2023 11."
"The gold standard diagnostic test for SARS-CoV-2 is the real-time reverse transcriptase polymerase chain reaction (RT-PCR) test 4."
"SARS-CoV-2 is an enveloped, single-stranded RNA betacoronavirus that enters respiratory epithelium via the angiotensin-converting enzyme 2 (ACE2) receptor. It is one of the two strains of the SARS-CoV species known to cause human disease, the other being the original severe acute respiratory syndrome coronavirus (SARS-CoV-1), causing SARS. The virus mutates continually; lineages with altered transmissibility or immune escape are designated variants of concern or interest by the WHO 2."

"Most infections are mild and confined to the upper respiratory tract, with the Omicron variant now dominant 33; pneumonia and severe disease are concentrated in older, immunosuppressed, and comorbid individuals 12. Common symptoms include fever, cough, fatigue, and/or dyspnoea 12,13. Anosmia/taste disturbance is less common with the Omicron variant now dominant 33."

"pulmonary embolism: higher in intensive care (~25%) than on the ward (~10%); emboli are frequently peripheral and often occur without demonstrable deep vein thrombosis 20,21"
"absorption stage (>14 days): gradual resolution; residual parenchymal bands"
"Disease extent can be quantified with a CT severity score; a higher score is associated with intensive care admission and death in a strong dose-response relationship 16."
"ground-glass opacities (GGO): bilateral, peripheral and basal (often rounded or multifocal) (>70%)"
"air space consolidation and other features of organising pneumonia (e.g. reverse halo sign) (~50%)"
