COVID-19 is caused by the Severe Acute Respiratory
Syndrome Coronavirus 2 (SARS-CoV-2), and is closely related to
SARS-CoV-1 (Severe Acute Respiratory Syndrome Coronavirus 1) and
MERS-CoV (Middle Eastern Respiratory Syndrome Coronavirus). Imaging
studies have shown that COVID-19 results in pneumonia with
“ground-glass opacification, consolidation, bilateral involvement,
and peripheral and diffuse distribution.” (Lee et al (2020);
The Lancet, 20(4), 384).
