These differences can be attributed to the relatively mild symptoms of patient. However, in our case, leukocytes, ratio of neutrophils and lymphocytes remains normal. The main manifestations on CT are patchy/punctate ground glass opacities with a single lobe or multiple lobes involvement. Laboratory examination shows that the absolute number of leukocytes, neutrophils and lymphocytes decrease in most patients, while CRP increases significantly and procalcitonin is usually normal. The majority of patients have respiratory symptoms. The 2019-nCoV (officially named by the World Health Organization as COVID-19) is the seventh member of the coronavirus family which includes two highly pathogenic viruses (SARS-CoV and MERS-CoV) causing severe respiratory syndrome in humans and four other coronaviruses (HCoV-OC43, HCoV-229E, HCoV-NL63, HCoV-HKU1) causing mild upper respiratory disease. CT scan showed multiple patchy/ground glass shadows in both lungs, as shown in Fig. Finally, he was diagnosed with 2019-nCoV based on the real-time reverse-transcriptase-polymerase chain reaction (rRT-PCR) amplification of the viral DNA from a pharyngeal examination sample. Among the inflammatory factors, ferritin (876.90В Ојg/L), interleukin-6 (39.6), interleukin-2r (744.0) and Tumor necrosis factor-О± (18.5) increased significantly. Immune examination showed the antibodies of Legionella pneumophila, Mycoplasma pneumoniae, Coxiella burnetii, Chlamydia pneumoniae, adenovirus, respiratory syncytial virus, influenza A virus, influenza B virus, parainfluenza virus (1,2,3) were all negative. Biochemical examination showed that leukocytes (6.8В Г—В 109/L), ratio of neutrophils (68.80%) and lymphocytes (27.6%), procalcitonin (<В 0.05В ng/ml) were all in the normal range, while the ratio of eosinophils to leukocytes (0.1%) decreased slightly.

The physical examination showed the body temperature was 38. The patient complained of poor appetite and low urine volume (about 500В ml per day) recently. On February 6, the patient had a dry cough and chest tightness. One day later, the patient developed chills and fever, with a maximum body temperature of 37. The patient had diarrhea 2-3 times a day on February 4, which was yellow paste stool. 10 days ago, he had contacted with his son-in-law who went to Wuhan for a meeting on January 21 and was recently diagnosed as NCIP. The patient had a history of hypertension, diabetes and hyperlipidemia, but controlled well. A 62-year-old man with diarrhea for 3 days and fever for 2 days was admitted to the Fever clinic of the First Affiliated Hospital of Anhui Medical University (AHMU) in Feb 7, 2020.
