T18 162-249 Sentence denotes This pneumonia was later confirmed to be secondary to infection by a novel coronavirus.
T19 250-568 Sentence denotes This virus was originally called the 2019 novel coronavirus (2019-nCoV), but on February 11, 2020, the disease was named COVID-19 by the World Health Organization (WHO), and the virus was named “severe acute respiratory syndrome coronavirus 2” (SARS-CoV-2) by the International Committee on Taxonomy of Viruses (ICTV).
T20 569-695 Sentence denotes It is believed that the COVID-19 outbreak has a zoonotic origin and began in the Huanan wet seafood wholesale market in Wuhan.
T21 696-786 Sentence denotes SARS-CoV-2 has proven to be extremely contagious and spreads easily from person to person.
T22 787-948 Sentence denotes Cases of COVID-19 have now spread beyond Wuhan to many other provinces in China as well as other countries, which has raised international attention and concern.
T23 949-1101 Sentence denotes As of March 12, 2020, more than 81,000 human infections with SARS-CoV-2 and at least 3100 deaths related to COVID-19 have been confirmed in China alone.
T24 1102-1223 Sentence denotes Although the epidemic situation in China has been relatively under control, the situation outside China is getting worse.
T25 1224-1486 Sentence denotes So far, the COVID-19 viral disease that has swept into at least 114 countries with more than 60,000 cases diagnosed and more than 4000 people killed is now officially a pandemic, as WHO Director-General Tedros Adhanom Ghebreyesus announced in Geneva on March 11.
T26 1487-1643 Sentence denotes At first, COVID-19 appeared in a few clusters and was more likely to affect persons with advanced age or other comorbidities, but it is now more widespread.
T27 1644-1779 Sentence denotes Infection can result in severe pneumonia and even fatal respiratory diseases such as acute respiratory distress syndrome (ARDS) [1, 2].
T28 1780-1962 Sentence denotes The main clinical presentation includes fever, dry cough, fatigue, and malaise and/or non-specific upper respiratory tract infection symptoms that may not be particularly noticeable.
T29 1963-2115 Sentence denotes As previously reported [1], patients with severe illness can develop dyspnea and some even developed ARDS and required ICU admission and oxygen therapy.
T30 2116-2243 Sentence denotes Laboratory findings of patients infected with SARS-CoV-2 include lymphopenia, elevated CRP, and erythrocyte sedimentation rate.
T31 2244-2391 Sentence denotes Genetic sequencing of SARS-CoV-2 has enabled the rapid development of point-of-care real-time RT-PCR diagnostic tests specific for COVID-19 [3, 4].
T32 2392-2508 Sentence denotes Novel coronavirus nucleic acids are detected in throat swabs, sputum, lower respiratory tract secretions, and blood.
T33 2509-2676 Sentence denotes At present, the diagnosis of COVID-19 is primarily based on the patient’s epidemiological history, clinical symptoms, chest imaging findings, and etiological evidence.
T34 2677-2775 Sentence denotes Viral nucleic acid testing is an important diagnostic criterion; however, it has some limitations.
T35 2776-3019 Sentence denotes False negatives from viral nucleic acid testing arise from the uneven quantity of detection technology, disease characteristics (asymptomatic patients), and status of epidemic prevention and control, as well as errors in clinical sampling [5].
T36 3020-3179 Sentence denotes COVID-19 is highly contagious; thus, early detection and diagnosis are of paramount importance to isolate suspected cases and contacts to control the outbreak.
T37 3180-3360 Sentence denotes The challenges in identification of pathogens by viral nucleic acid testing have made some frontline clinicians propose CT as a diagnostic method for identifying COVID-19 patients.
T38 3361-3483 Sentence denotes This review aims to briefly introduce the novel coronavirus pneumonia and highlight the value of imaging in its diagnosis.
