Novel Coronavirus Pneumonia is an acute infection that often progressively worsens in the first week. If you encounter any of the following conditions, you should seek medical attention and have your doctor rule out infection through relevant examinations. Recent occurrence of unexplained fever, fatigue, cough, etc.; history of living in Wuhan or traveling in the two weeks prior to the onset of the disease; close contact with people in the infected area in the two weeks prior to the onset of the disease; aggregation of the disease (more than two people) What examinations do the patients need to undergo? 1. Physical examination Doctors will carry out relevant examinations for the condition of the lungs, and auscultation of pulmonary respiratory sounds. Laboratory tests Early in the disease, the total number of white blood cells is normal or decreased, the lymph count is decreased, and liver enzymes and myoglobin are increased in some patients. Most patients have elevated C-reactive protein and blood sedimentation, and normal calcitoninogen. In severe cases, D-dimer is elevated. 3.Imaging examination Early show multiple small patchy shadow and interstitial changes, with the outer lung band obvious, and then develop into double lungs multiple grinding glass shadow, infiltration shadow, serious cases can appear lung solid change, even “white lung”, pleural effusion is rare. 4. Pathogen detection: Collect pharyngeal swab, sputum or lower respiratory tract secretion specimen, and conduct real-time fluorescence RT-PCR (new coronavirus pneumonia kit), the result is positive for the detection of new coronavirus nucleic acid. 5. Gene sequencing The gene sequencing of the pathogen suggests a high degree of homology with the novel coronavirus. Diagnostic criteria for novel coronavirus 1. How to identify suspected cases of novel coronavirus pneumonia Combine the epidemiological history and clinical manifestations and analyze them comprehensively. The presence of any one item in the epidemiological history and the presence of any two items in the clinical manifestations can be regarded as a suspected case. Epidemiologic history History of travel or residence in Wuhan or other areas with persistent transmission of local cases within 14 days before the onset of the disease; Contact with patients with fever or respiratory symptoms from Wuhan or other areas with persistent transmission of local cases within 14 days before the onset of the disease; Epidemiologic association of people with clustered morbidity or novel coronavirus infection. Clinical manifestations Fever; imaging features of pneumonia as described above; normal or decreased white blood cell count or decreased lymphocyte count early in the course of the illness. 2. Criteria for confirming the diagnosis of novel coronavirus pneumonia A suspected case can be diagnosed as novel coronavirus pneumonia if it has one of the following pathogenetic evidence. Respiratory specimen or blood specimen real-time fluorescence RT-PCR test positive for nucleic acid of the new coronavirus; Respiratory specimen or blood specimen viral gene sequencing, and the known new coronavirus is highly homologous.
