The season is now in the middle of winter or alternating winter and spring, which is also the season of high incidence of respiratory diseases. Nowadays, in addition to pneumonia from novel coronavirus pneumonia, some patients may also contract the common cold, influenza A, influenza B, bronchitis, or develop pneumonia problems. All of these problems may manifest as respiratory tract inflammation, which also manifests as cough, cough and fever manifestations. Therefore, it is possible to confuse this period with a patient with novel coronavirus pneumonia, or even some people mistakenly think they are infected with the novel coronavirus virus. In this case, it is necessary to review whether you have been to the infected area recently or whether you have a history of close contact with a patient with novel coronavirus pneumonia. If there is a history of close contact and then respiratory symptoms occur, it may be more important for my doctor to consider ruling out novel coronavirus infection. If the symptoms persist with fever, cough and other symptoms similar to those of novel coronavirus pneumonia, pathogenic tests may also be performed to test for viral nucleic acid. If the nucleic acid test is positive, it can also prove that the infection is a novel coronavirus. Content source: Dr. You Lai
