Abstract
Coronavirus disease (COVID-19) pneumonia is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) [1, 2]. It is highly infectious and spreads through respiratory droplets, contact, and the fecal-oral route. It is characterized by acute onset and severe symptoms and is a serious threat to human health and safety. According to the latest diagnosis and treatment scheme for COVID-19 pneumonia issued by the National Health Commission of the People’s Republic of China (trial version 8), the diagnosis of COVID-19 pneumonia is mainly based on epidemiologic factors, clinical manifestations, computed tomography (CT) findings, and nucleic acid detection of SARS-CoV-2.
