3 Case Diagnosis

Differences of diagnosis criteria between Hubei Province and other provinces were deleted and unified as “suspected cases” and “confirmed cases”.

There are two judgements of suspected cases. First, “patients meet any one of the epidemiological exposure histories as well as any two of the clinical manifestations (fever and/or respiratory symptoms; having the imaging features of pneumonia mentioned above; in the early stage, a normal or decrease of total white blood cells count and a decrease of lymphocyte count can be found).Second,” patients without definite epidemiological exposure history but meet the three clinical manifestations(fever and/or respiratory symptoms; having the imaging features of pneumonia mentioned above; in the early stage, a normal or decrease of total white blood cells count and a decrease of lymphocyte count can be found)”.

Positive pathogen evidences are required for confirmed cases(a positive result of the nucleic acid of 2019-nCoV by real-time fluorescence RT-PCR, or the virus gene sequence is highly homologous to the known 2019-nCoV).
