In the current period of novel coronavirus epidemic, how to determine whether you are infected with novel coronavirus is an important issue that needs to be clarified. The pathogen of novel coronavirus pneumonia is a novel coronavirus, which does not exist in the normal living environment and can only be infected with a novel coronavirus if you are in an infected area or come into contact with a patient with a novel coronavirus. Therefore, judging from the epidemiological characteristics, having contact with the virus is a prerequisite. A positive result for the nucleic acid of the novel coronavirus indicates infection with the novel coronavirus. It can also be determined clinically, if there is a clear history of exposure and a clinical presence of cough, fever and characteristic shadows in the lungs, the patient can also be considered to be infected with the novel coronavirus. Pathogenetic examination is the most important basis for confirming the diagnosis. Content source: Dr. Yurai
