Cough symptoms are a common clinical manifestation of respiratory diseases. Whether it is pneumonia or infectious diseases such as bronchitis, bronchial asthma, or bronchiectasis, cough may be present. Novel coronavirus pneumonia manifests as a persistent cough, and cough symptoms may persist and worsen. In addition to cough manifestations, fever and progressive dyspnea may be present. Common pneumonia cough may manifest as cough and sputum, may or may not be accompanied by fever, and some patients may have pulmonary solid lesions and may also have dyspnea. There are some differences in disease severity between patients with general pneumonia and those with novel coronavirus pneumonia, but the most critical difference is the pathogenetic testing. The nucleic acid test for novel coronavirus is positive, and imaging shows a patchy ground-glass-like shadow, or even multiple shadows, on the outer lung bands. Content source: Dr. Yurai
