Since January 15, 2020, the General Office of the National Health Commission of China has successively issued nine editions of the diagnosis and treatment plan for COVID-19 (serious special infectious pneumonia, new coronary pneumonia, Wuhan pneumonia). The National Health Commission of China also reports daily figures including the number of newly confirmed cases, new suspected cases and new asymptomatic infections in the country. What are the criteria for suspected and confirmed cases of new coronary pneumonia in China?
Looking at the previous editions of the "New Coronary Virus Pneumonia Diagnosis and Treatment PlaWuhan, it also mentions Special Database asymptomatic infections. The diagnostic criteria for suspected cases in this protocol include "clinical manifestations related to COVID-19 such as fever and/or respiratory symptoms", imaging features of COVID-19, etc. Confirmed cases are suspected cases with etiological or serological evidence including "positive real-time fluorescent RT-PCR nucleic acid for novel coronavirus". The Diagnosis and Treatment Plan for Novel Coronavirus Pneumonia (Trial Version 8 Revised Edition) issued by the National Health
Commission of China on April 14, 2021 and the Diagnosis and Treatment Plan for Novel Coronavirus Pneumonia (Trial Version 9) issued on March 14, 2022 , which basically continued the eighth edition of the diagnostic criteria for suspected and confirmed cases. Judging from the diagnostic criteria stipulated in the previous editions of China's "New Coronary Virus Pneumonia Diagnosis and Treatment Program", in addition to "real-time fluorescent RT-PCR detection of novel coronavirus nucleic acid positive", "fever and imaging features of novel coronavirus pneumonia" are always in the China's standard for diagnosing new coronavirus infections as new confirmed cases of new coronavirus pneumonia.
