H5N1 virus: highly pathogenic human avian influenza viral pneumonia, the imaging manifestation of intrapulmonary patchy shadow, rapid progress can be seen in the case of a large area of ground-glass shadow, lung solid shadow, or even diffuse solid shadow, may appear pleural effusion. 3. New coronavirus: Early stage may show multiple small patchy shadows and interstitial changes, and the progression of the disease may show multiple ground-glass shadows and infiltration shadows in both lungs, and even progress to pulmonary solid changes.
